The Most Versatile VoIP Provider: FREE PORTING

A Cloud-Based Asterisk PBX: 0 to $5/Mo.

In our last post, we catalogued the various ways to deploy an Asterisk® PBX using existing Windows, Mac, or Linux desktop hardware. But that solution isn’t ideal for everyone especially if you’re looking for a cloud-based platform that provides redundancy and backups. So today we’ll introduce some cloud platform Asterisk solutions, at least one of which can be deployed in under five minutes.

Let’s begin with our personal favorite, CrownCloud. For $25 a year, you get a 5-minute install from an Incredible PBX snapshot in your choice of locations: Los Angeles, Atlanta, Miami, Germany, or The Netherlands. You also get a free backup image. And, of course, you get the full complement of Incredible PBX utilities which set this deployment apart from all the other FreePBX® offerings.

It’s not every day that you get an opportunity to deploy an Incredible PBX® server on a cloud platform as robust as the one offered by Oracle®. And the fact that it won’t cost you a dime EVER makes this all the more appealing. This isn’t some bargain basement, crippled cloud platform with barely enough horsepower to get your server booted. Quite the contrary, this is an ARM-based Ubuntu 20.04 platform with 6GB of RAM, 45+ GB of storage, and a 1GB network pipe. The CPU capacity is equivalent to multiple physical cores of an Intel Xeon processor with hyper threading enabled. Read our step-by-step installation tutorial for deployment instructions. This install is best suited for those with some networking experience.

If you want a low cost Cloud solution that’s easy to deploy, you can’t beat RackNerd’s KVM Cloud platform for $12.98 a year which works out to just over $1 a month. The Incredible PBX 2027 tutorial for Ubuntu 22.04 will have you up and running in under an hour with the latest releases of Asterisk 20 and FreePBX 16.

Let’s finish with the elephants in the room: Amazon, Google, IBM, Microsoft, and Oracle. They all have cloud offerings, and our recommendation is don’t go there. Their services are EXPENSIVE. And they offer less functionality at significantly higher cost than some of the smaller, well-established companies such as Vultr and Digital Ocean. If $5 to $6 (with backups) a month for a cloud platform is not too rich for your blood, you can’t go wrong with either of these. And just like with RackNerd, the Incredible PBX 2027 tutorial for Ubuntu 22.04 will have you up and running in under an hour.

The 5-Minute PBX in the Cloud Platform for $2 a Month

If $2.10 a month for a state-of-the-art VoIP PBX isn’t too rich for your blood, then today’s your lucky day. What that buys you is a turnkey, cloud-based PBX platform that is fully installed and configured IN LESS THAN 5 MINUTES! Did we mention the feature set? The Incredible PBX 2027-U image at CrownCloud has an unequaled feature set: Ubuntu 22.04 LTS, Asterisk® 20, and FreePBX® 16 with preconfigured extensions and trunks for dozens of VoIP providers plus voicemail with transcription and email delivery, IVRs, DISA, SMS messaging, conferencing, call queues, paging, intercom, and lots of text-to-speech features to whet your developer appetite: news headlines, weather reports by zip code, today in history, and sample ODBC apps for customer and accounting lookups using MySQL/MariaDB databases. The web server offerings include the latest FreePBX GUI with all of its GPL modules plus WebMin, AsteriDex, and Telephone Reminders. It’s taken us more than a decade to develop this free platform. You get to take advantage of it in less than 5 minutes.

So what’s the difference in today’s $2 a month offering from CrownCloud and the previous offering from RackNerd for $1 a month. The major difference is Incredible PBX 2027-U is an actual image offering at CrownCloud while, at RackNerd, you had to first install the operating system and then go through the entire setup procedure for the Incredible PBX platform of your choice. The CrownCloud scenario takes five minutes while the RackNerd procedure consumes more than an hour assuming all of the repositories upon which Incredible PBX relies are on line and functioning as advertised. What you’ll quickly learn with open source software is this. We rely upon the work product of over 1,000 different individuals and companies, any one of whom can seriously break things either because their software is off-line or because they’ve "improved" something in a way that quickly cascades into a disaster for those of us that relied upon their old way of doing things. If patience and time are your strong suits, then the $1 a month alternative may be a perfect fit. Otherwise, our new CrownCloud image of Incredible PBX 2027-U is a godsend. So let’s get started.

Getting Started at CrownCloud

These 5-minute turnkey installs of Incredible PBX 2027-U for Ubuntu 22.04 are offered at the jaw-dropping price of $25 a year. The monthly cost is cheaper than a cup of coffee at Starbucks, and you’ll have a fully-functioning, production-ready KVM platform including a free snapshot with 1GB RAM, 20GB SSD storage, and 1TB of monthly bandwidth in your choice of server locations including Los Angeles, Miami, and Atlanta in the United States as well as Germany and the Netherlands in Europe. And, unlike all of the other Asterisk® aggregations, Incredible PBX still provides a source code-based platform that can be tailored to meet any special requirements your organization may need.

It’s worth mentioning that we don’t make a nickel on these cloud offerings so consider this our special thanks to all of our loyal fans.

Here are the links to sign up for the service and take advantage of the Incredible PBX 2027 deal:

After you sign up for the service, open the CrownPanel application and choose Incredible PBX 2027-U under Application Images for your base install. Take a 5-minute coffee break while your server image is installed. Once your server comes on line, login as root from a desktop machine using the password that was provided. Be sure to use SSH and NOT the VNC utility included in CrownPanel. This will assure that your desktop machine’s IP address gets whitelisted in the Incredible PBX firewall. Otherwise, you won’t be able to SSH into your server from your desktop. Once you login, the Incredible PBX configurator will prompt you to set passwords for root login, admin login to FreePBX, and admin login credentials for Apache to access AsteriDex and Reminders. Add a trunk provider (Skyetel is preconfigured and enabled by default) and a softphone or Incredible PBX SIP phone, and your PBX is ready to go.

Planning Ahead for That Rainy Day

One of our favorite features of Crown Cloud is the free snapshot (a.k.a. backup) that’s provided at no additional charge. We recommend you take snapshots regularly as you make major changes in your server’s configuration. In this way, if something comes unglued, you can easily restore the snapshot and never miss a beat. You’ll find the Remote Snapshot option in your CrownPanel menu.

Next Steps with Incredible PBX 2027

Before you can manage your PBX through a web browser, you first will need to set the root password for Ubuntu as well as the admin passwords for FreePBX and Apache web apps such as Reminders and AsteriDex. These all can be set by logging into your server as root and issuing the following commands: passwd, admin-pw-change, and apache-pw-change.

Outbound mail functionality needs to be working so that you can receive voicemail messages and faxes by email. To prevent SPAM, most ISPs and ITSPs block messages from downstream mail servers. That would be you. The easiest way to resolve this is to configure SendMail using Gmail as an SMTP Smarthost. You obviously need a Gmail account to implement this and you also will need to obtain an App password for your Gmail account, and use that in lieu of your regular Gmail password when configuring SendMail. With your Gmail username and App password in hand, log into your server as root and run: /root/enable-gmail-smarthost-for-sendmail.

If your Incredible PBX 2027 is hosted with a cloud provider, be advised that many providers do not include a swap file as part of their offering. FreePBX requires a swap file. To see if you have one, issue the command: free -h. To add one, issue this command after logging into your server as root: /root/create-swapfile-DO.

To correctly set the time on your PBX, run: /root/timezone-setup.

By default, the voicemail password for each of the configured extensions (701-705) is set to the extension number. This means the user will be prompted to set a voicemail password on the first login to voicemail for each extension. A phone must be registered to the actual extension to access its voicemail account. For example, once a phone is registered to extension 701, the voicemail setup can be accessed by dialing *98701.

Overview of the Initial Asterisk Setup Process

For those new to PBXs, here’s a two paragraph summary of how Voice over IP (VoIP) works. Phones connected to your PBX are registered with Extensions so that they can make and receive calls. When a PBX user picks up a phone and dials a number, an Outbound Route tells the PBX which Trunk to use to place the call based upon established dialing rules. Unless the dialed number is a local extension, a Trunk registered with some service provider accepts the call, and the PBX sends the call to that provider. The provider then routes the call to its destination where the recipient’s phone rings to announce the incoming call. When the recipient picks up the phone, the conversation begins.

Looking at things from the other end, when a caller somewhere in the world wishes to reach you, the caller picks up a telephone and dials a number known as a DID that is assigned to you by a provider with whom you have established service. When the provider receives the call to your DID, it routes the call to your PBX based upon destination information you established with the provider. Your PBX receives the call with information identifying the DID of the call as well as the CallerID name and number of the caller. An Inbound Route on your PBX then determines where to send the call based upon that DID and CallerID information. Typically, a call is routed to an Extension, a group of Extensions known as a Ring Group, or an IVR or AutoAttendant giving the caller choices on routing the call to the desired destination. Once the call is routed to an Extension, the PBX rings the phone registered to that Extension. When you pick up the phone, the conversation begins.

Configuring Trunks with Incredible PBX GUI

Perhaps the most difficult component to configure in the PBX is the Trunk. Almost every provider has a different way of doing things. We’ve taken some of the torture out of the exercise by providing a script which will configure settings for dozens of providers in seconds. Once installed, all you need to do is edit the desired Trunk (Connectivity:Trunks), change the Disable Trunk entry to No, and insert your credentials in both the PEER Details and Registration string of the SIP Settings Outgoing and Incoming tabs. Skyetel is enabled by default and needs no setup on the PBX side.

Configuring Skyetel for Incredible PBX 2027

If you’ve decided to go with Skyetel, here’s the drill. Sign up for Skyetel service and take advantage of the Nerd Vittles specials. First, complete the Prequalification Form here. You then will be provided a link to the Skyetel site to complete your registration. Once you have registered on the Skyetel site and your account has been activated, open a support ticket and request the $10 credit for your account by referencing the Nerd Vittles special offer. Once you are satisfied with the service, fund your account as desired, and Skyetel will match your deposit of up to $250 simply by opening another ticket. That gets you up to $500 of half-price calling. Credit is limited to one per person/company/address/location. Effective 10/1/2023, $25/month minimum spend required.

Skyetel does not use SIP registrations to make connections to your PBX. Instead, Skyetel utilizes Endpoint Groups to identify which servers can communicate with the Skyetel service. An Endpoint Group consists of a Name, an IP address, a UDP or TCP port for the connection, and a numerical Priority for the group. For incoming calls destined to your PBX, DIDs are associated with an Endpoint Group to route the calls to your PBX. For outgoing calls from your PBX, a matching Endpoint Group is required to authorize outbound calls through the Skyetel network. Thus, the first step in configuring the Skyetel side for use with your PBX is to set up an Endpoint Group. Here’s a typical setup for Incredible PBX 2027:

  • Name: MyPBX
  • Priority: 1
  • IP Address: PBX-Public-IP-Address
  • Port: 5060
  • Protocol: UDP
  • Description: my.incrediblepbx.com

To receive incoming PSTN calls, you’ll need at least one DID. On the Skyetel site, you acquire DIDs under the Phone Numbers tab. You have the option of Porting in Existing Numbers (free for the first 60 days after you sign up for service) or purchasing new ones under the Buy Phone Numbers menu option.

Once you have acquired one or more DIDs, navigate to the Local Numbers or Toll Free Numbers tab and specify the desired SIP Format and Endpoint Group for each DID. Add SMS/MMS and E911 support, if desired. Call Forwarding and Failover are also supported. That completes the VoIP setup on the Skyetel side. System Status is always available here.

Configuring VoIP.ms for Incredible PBX 2027

To sign up for VoIP.ms service, may we suggest you use our signup link so that Nerd Vittles gets a referral credit for your signup. Once your account is set up, you’ll need to set up a SIP SubAccount and, for Authentication Type, choose Static IP Authentication and enter your Incredible PBX 2027 server’s public IP address. For Transport, choose UDP. For Device Type, choose Asterisk, IP PBX, Gateway or VoIP Switch. Order a DID in their web panel, and then point the DID to the SubAccount you just created. Be sure to specify atlanta1.voip.ms as the POP from which to receive incoming calls. In the Incredible PBX GUI, be sure to enable the VoIP.ms trunk.

Configuring V1VoIP for Incredible PBX 2027

To sign up for V1VoIP service, sign up on their web site. Then login to your account and order a DID under the DIDs tab. Once the DID has been assigned, choose View DIDs and click on the Forwarding button beside your DID. For Option #1, choose Forward to IP Address/PBX. For the Forwarding Address, enter the public IP address of your server. For the T/O (timeout) value, set it to 2o seconds. Then click the Update button. Under the Termination tab, create a new Endpoint with the public IP address of your server so that you can place outbound calls through V1VoIP. In the Incredible PBX GUI, be sure to enable all of the V1VoIP trunks.

Configuring Anveo Direct for Incredible PBX 2027

To sign up for Anveo Direct service, sign up on their web site and then login. After adding funds to your account, purchase a DID under Inbound Service -> Order DID. Next, choose Configure Destination SIP Trunk. Give the Trunk a name. For the Primary SIP URI, enter $[E164]$@server-IP-address. For Call Options, select your new DID from the list. You also must whitelist your public IP address under Outbound Service -> Configure. Create a new Call Termination Trunk and name it to match your server. For Dialing Prefix, choose six alphanumeric characters beginning with a zero. In Authorized IP Addresses, enter the public IP address of your server. Set an appropriate rate cap. We like $0.01 per minute to be safe. Set a concurrent calls limit. We like 2. For the Call Routing Method, choose Least Cost unless you’re feeling extravagant. For Routes/Carriers, choose Standard Routes. Write down your Dialing Prefix and then click the Save button.

Before you can make outbound calls through Anveo Direct from your PBX, you first must configure the Dialing Prefix that you wrote down in the previous step. Log into the GUI as admin using a web browser and edit the Anveo-Out trunk in Connectivity -> Trunks. Enable the Trunk. Then click on the custom-Settings tab and replace anveo-pin with your actual Dialing Prefix. Click Submit and Apply Config to complete the setup. In the Incredible PBX GUI, be sure to enable all of the remaining Anveo trunks.

By default, incoming Anveo Direct calls will be processed by the Default inbound route on your PBX. If you wish to redirect incoming Anveo Direct calls using DID-specific inbound routes, then you’ve got a bit more work to do. In addition to creating the inbound route using the 11-digit Anveo Direct DID, enter the following commands after logging into your server as root using SSH/Putty:

cd /etc/asterisk
echo "[from-anveo]" >> extensions_custom.conf
echo "exten => _.,1,Ringing" >> extensions_custom.conf
echo "exten => _.,n,Goto(from-trunk,\\${SIP_HEADER(X-anveo-e164)},1)" >> extensions_custom.conf
asterisk -rx "dialplan reload"

Configuring Extensions with Incredible PBX GUI

Extensions are created using the Incredible PBX GUI: Applications:Extensions. Many SIP phones expect extensions to communicate on UDP port 5060. If this is the case with your SIP phone or softphone, then always create Chan_SIP extensions which communicate on UDP 5060. If your SIP phone or softphone provide port flexibility, then you have a choice in the type of SIP extension to create: Chan_SIP or the more versatile PJSIP (UDP 5061). Just remember to always configure SIP extensions with NAT Mode=YES in the Advanced tab. If your VoIP phones or softphones support IAX connectivity, you may wish to consider IAX extensions which avoid NAT problems.

When you create a new Extension, a new entry is automatically created in the PBX Internal Directory. If you wish to allow individual users to manage their extensions or use the WebRTC softphone, then you will also have to create a (very) secure password for User Control Panel (UCP) access. Choose Admin:User Management and click on the key icon of the desired extension to assign a password for UCP and WebRTC access.

Configuring a Desktop Softphone for Incredible PBX

We’re in the home stretch now. You can connect virtually any kind of telephone to your new PBX. Plain Old Phones require an analog telephone adapter (ATA) which can be a separate board in your computer from a company such as Digium. Or it can be a standalone SIP device such as ObiHai’s OBi100 or OBi110 (if you have a phone line from Ma Bell to hook up as well). SIP phones can be connected directly so long as they have an IP address. These could be hardware devices or software devices such as a softphone. We’ll start with a free one today so you can begin making calls. You can find dozens of recommendations for hardware-based SIP phones both on Nerd Vittles and the PIAF Forum when you’re ready to get serious about VoIP telephony.


The easiest way to get started is to download a free softphone onto your desktop. We recommend Zoiper 5 for personal use. You can download and install it from here. Once installed, you’ll first need to decipher your extension password for an extension you wish to use to connect to Zoiper. Log into your Linux CLI and switch to the root user as documented above. Then run: /root/show-passwords. Specify 701 and 705 as the starting and ending extensions. Make note of the 701 extension password. Run pbxstatus and make note of your LAN IP address, e.g. 179.xx.yy.zz. Next, start up Zoiper from your desktop and choose the free version. For the desired account enter: 701@179.xx.yy.zz:5061 where 179.xx.yy.zz is the local IP address of your virtual machine. For the password, enter the 701 extension password you deciphered above. Press ENTER twice to complete the connection. When the dialer appears, try out some of the free Incredible PBX applications below.

NOTE: You must use the Keypad option shown in the right window of Zoiper after your call is connected for any app that prompts for keyboard input.

Here are some numbers to try:

123 - Reminders
222 - Timeclock for Employees (try 12345)
223 - AsteriDex Lookup & Dialer (try 335 for Delta Airlines)
947 - Weather by ZIP Code (requires keyboard entry of ZIP code)
951 - Yahoo News
TODAY - Today in History
LENNY - The Telemarketer's Worst Nightmare

If you are a Mac user, another great no-frills softphone is Telephone. Just download and install it from the Mac App Store. For Android users, check out the terrific new VitalPBX Communicator. Works flawlessly with Incredible PBX.

Configuring a Softphone Extension on a Smartphone

Adding an Incredible PBX extension to your smartphone gets a little trickier. Whether you’re an iPhone or Android lover, all smartphones use batteries, and you don’t want to drain your battery by running a softphone as a foreground app all the time. Fortunately, you now have some choices in softphones engineered to work without draining your battery. While they all cost money, it’s not much money. We’ve written about all the choices, and you’ll find the links in our Softphone Provider Recommendations on the new Incredible PBX Wiki.

With PJsip extensions, you’re not limited to a single phone connection at a time, and we’ve preconfigured extension 701 to support ten simultaneous connections. The setup on the softphone side is simple. For the server, enter the actual IP address of your PBX in the following format: 22.33.44.55:5061. Then enter 701 for the username and enter the password assigned to the 701 extension on your PBX. When an incoming call arrives, all the phones registered to extension 701 will ring simultaneously. Simply answer the call on the phone that is most convenient. For extension 702, you can change the number of simultaneous connections by clicking the Advanced tab and setting the number in Max Contacts.

Configuring Outbound Routes in Incredible PBX GUI

Outbound Routes serve a couple of purposes. First, they assure that calls placed by users of your PBX are routed out through an appropriate trunk to reach their destination in the least costly manner. Second, they serve as a security mechanism by either blocking or restricting certain calls by requiring a PIN to complete the calls. Never authorize recurring charges on credit cards registered with your VoIP providers and, if possible, place pricing limits on calls with your providers. If a bad guy were to break into your PBX, you don’t want to give the intruder a blank check to make unauthorized calls. And you certainly don’t want to join the $100,000 Phone Bill Club.

To create outbound routes in the Incredible PBX GUI, navigate to Connectivity:Outbound Routes and click Add Outbound Route. In the Route Settings tab, give the Outbound Route a name and choose one or more trunks to use for the outbound calls. In the Dial Patterns tab, specify the dial strings that must be matched to use this Outbound Route. NXXNXXXXXX would require only 10-digit numbers with the first and fourth digits being a number between 2 and 9. Note that Outbound Routes are searched from the top entry to the bottom until there is a match. Make certain that you order your routes correctly and then place test calls watching the Asterisk CLI to make sure the calls are routed as you intended.

Configuring Inbound Routes in Incredible PBX GUI

Inbound Routes, as the name implies, are used to direct incoming calls to a specific destination. That destination could be an extension, a ring group, an IVR or AutoAttendant, or even a conference or DISA extension to place outbound calls (hopefully with a very secure password). Inbound Routes can be identified by DID, CallerID number, or both. To create Inbound Routes, choose Connectivity:Inbound Routes and then click Add Inbound Route. Provide at least a Description for the route, a DID to be matched, and the Destination for the incoming calls that match. If you only want certain callers to be able to reach certain extensions, add a CallerID number to your matching criteria. You can add Call Recording and CallerID CNAM Lookups under the Other tab.

Audio Issues with Incredible PBX 2027

While it is always a good idea anyway, if you experience one-way or no audio on some calls, be sure to add your external IP address and LAN subnet in the GUI by navigating to Settings -> Asterisk SIP Settings. In the NAT Settings section, click Detect Network Settings. Click Submit and Apply Settings to save your changes.

Adding Fax Support to Incredible PBX 2027

We’ve had to live without faxing on the new Incredible PBX 2027 platforms since the beginning of the year. But those days are over. If you’d like to add fax support to your virtual machine, head over to our new Fax Tutorial to install the components. It only takes a couple minutes.

Adding Incredible PBX 2027 to an OpenVPN Network

We previously have documented the procedure for creating an OpenVPN server as well as OpenVPN client templates (.ovpn). If you need a refresher, the tutorial is here. To add your Incredible PBX 2027 server to an existing OpenVPN network, begin by creating an incrediblepbx2027.ovpn template on your OpenVPN server. Be sure to comment out or delete the setenv line in the template. Then copy this template to /etc on your Incredible PBX 2027 server. The following commands are already in place:

echo "[Unit]
Description=openvpn2027
ConditionPathExists=/etc/openvpn-start
After=rclocal.service
[Service]
Type=forking
ExecStart=/etc/openvpn-start /etc/incrediblepbx2027.ovpn
TimeoutSec=0
StandardOutput=tty
RemainAfterExit=yes
PermissionsStartOnly=true
SysVStartPriority=99
[Install]
WantedBy=multi-user.target" > /etc/systemd/system/openvpn2027.service

We’ve also enabled this openvpn2027.service which will start when you reboot your server. The OpenVPN IP address should now appear on the LAN line in pbxstatus:

systemctl enable openvpn2027.service
reboot

Deploying ODBC Apps with Incredible PBX 2027

Appreciating that many use a PBX to perform actual tasks for your business, we have included two sample ODBC apps to give you a head start. The code for these ODBC apps is stored in odbc.conf in the /etc/asterisk folder. Dialing 222 from any Asterisk extension calls up the TimeClock application which provides access to an employee database. You can enter 12345 as an employee number to see how it works. Dialing 223 from any Asterisk extension connects to the AsteriDex MySQL database and performs a lookup based upon the 3-digit code corresponding to the first three letters of the company name. For example, entering 335 (D-E-L) will call up the entry for Delta Airlines and connect you to their reservations desk once you have an outbound trunk enabled. You could build something similar to look up real-time inventory information from a MySQL database. These are just examples of the thousands of applications that could be quickly developed using ODBC and the Incredible PBX 2027 platform.

Incredible PBX 2027 Administration

We’ve eased the pain of administering your new PBX with a collection of scripts which you will find in the /root folder after logging in with SSH or Putty. Here’s a quick summary of what each of the scripts does.

add-fqdn is used to whitelist a fully-qualified domain name in the firewall. Because Incredible PBX 2027 blocks all traffic from IP addresses that are not whitelisted, this is what you use to authorize an external user for your PBX. The advantage of an FQDN is that you can use a dynamic DNS service to automatically update the IP address associated with an FQDN so that you never lose connectivity.

add-ip is used to whitelist a public IP address in the firewall. See the add-fqdn explanation as to why this matters.

del-acct is used to remove an IP address or FQDN from the firewall’s whitelist.

admin-pw-change is used to set the admin password for access to the FreePBX/Incredible PBX web GUI using a browser pointed to the local IP address of your server.

apache-pw-change is used to set the admin password for access to Apache/Incredible PBX apps including AsteriDex and Reminders. This provides a password layer of protection for access to these applications.

incrediblebackup2021 makes a backup of critical components on your PBX to a tarball saved in /backup. This should be copied to safe location off-site for a rainy day.

incrediblerestore2021 restores a backup file which has been copied to the /backup folder.

ipchecker is a script which deciphers the public IP addresses associated with whitelisted FQDNs created with add-fqdn on your server. If any of the addresses have changed, the firewall is restarted after updating the IP addresses. By default, it is executed every 10 minutes by /etc/crontab.

licenses.sh displays the license associated with each of the FreePBX modules on your server.

logos-b-gone removes proprietary artwork from your PBX and is no longer necessary with the included IncrediblePBX FreePBX module.

mime-construct is a command-line utility to send emails with attachments.

neorouter-login is a script to add your PBX to a NeoRouter VPN. Tutorial here.

odbc-gen.sh is a script that was run to generate the ODBC settings for Asterisk. Do NOT use it.

openvpn-start is a script to add your PBX to an existing OpenVPN network using an .ovpn config file. Tutorial here.

pbxstatus displays status of all major components of Incredible PBX 2027.

pptp-install is a script to create a PPTP network connection for your PBX. Tutorial here.

purge-cdr-cel-records removes all CDR and CEL records from the MySQL database.

reset-conference-pins is a script that automatically and randomly resets the user and admin pins for access to the preconfigured conferencing application. Dial C-O-N-F from any registered SIP phone to connect to the conference.

reset-extension-passwords is a script that automatically and randomly resets ALL of the SIP passwords for extensions 701-705. Be careful using this one, or you may disable existing registered phones and cause Fail2Ban to blacklist the IP addresses of those users. HINT: You can place a call to the Ring Group associated with all five extensions by dialing 777.

reset-reminders-pin is a script that automatically and randomly resets the pin required to access the Telephone Reminders application by dialing 123. It’s important to protect this application because a nefarious user could set up a reminder to call a number anywhere in the world assuming your SIP provider’s account was configured to allow such calls.

show-feature-codes is a cheat sheet for all of the feature codes which can be dialed from any registered SIP phone. It documents how powerful a platform Incredible PBX 2027 actually is. A similar listing is available in the GUI at Admin -> Feature Codes.

show-passwords is a script that displays most of the passwords associated with Incredible PBX 2027. This includes SIP extension passwords, voicemail pins, conference pins, telephone reminders pin, and your Anveo Direct outbound calling pin (if configured). Note that voicemail pins are configured by the user of a SIP extension the first time the user accesses the voicemail system by dialing *97.

sig-fix disables Module Signature Checking in the FreePBX GUI. This should not be necessary unless you have added or edited FreePBX Modules with missing module signatures.

Forwarding Calls to Your Cellphone. Keep in mind that inbound calls to your DIDs automatically ring all five SIP extensions, 701-705. The easiest way to also ring your cellphone is to set one of these five extensions to forward incoming calls to your cellphone. After logging into your PBX as root, issue the following command to forward calls from extension 705 to your cellphone: asterisk -rx "database put CF 705 6781234567"

To remove call forwarding: asterisk -rx "database del CF 705"

Implementing Call By Name with 411

Once you have an Outbound Trunk and Route configured, deploying Call by Name by dialing 411 is simple. The way it works is to pick up any phone connected to your PBX and dial 411. When prompted for the name of the person or company to call, say the name as you entered it in the AsteriDex directory, e.g. Delta Air Lines. The name will then be looked up to decipher the number of the person or company to call. Then the call will be placed using your default outbound route. To deploy Call By Name, simply follow the setup instructions in this Nerd Vittles tutorial.

Introducing Adminer: The Ultimate MySQL Editor

If you’re as sick of phpMyAdmin as we are, you’ll be happy to know there’s a new kid on the block, Adminer. Better yet, the install procedure is a painless, one-minute exercise. The setup procedure for Incredible PBX 2027 is documented here. Once installed, you can connect to Adminer at http://server-ip-address/adminer. You should be prompted for your Apache admin credentials which were configured when you first installed Incredible PBX. Next, enter your MySQL root credentials and Adminer will display in all its glory. DO NOT OPEN PORT 80 FOR PUBLIC ACCESS, OR YOUR ENTIRE PBX WILL BE AT A HACKER’S MERCY!


Keeping FreePBX 16 Modules Current

We strongly recommend that you periodically update all of your FreePBX modules to eliminate bugs and to reduce security vulnerabilities. From the Linux CLI, log into your server as root and issue the following commands:

rm -f /tmp/*
fwconsole ma upgradeall
fwconsole reload
/root/sig-fix
systemctl restart apache2
/root/sig-fix

It’s Debian 11, Asterisk 19, & FreePBX 16: Come And Get It



We’ve been on a roll since March Madness by adding Rocky 8 to the Incredible PBX® portfolio. In addition to a native installer, we also added a VirtualBox image, a 5-minute CrownCloud setup, an amazing cloud-based platform for just $25 a year, and an experimental Debian 11, Asterisk 19, and FreePBX 16 platform.

Now that fall is just around the corner, we have tweaked our three new Incredible PBX offerings: Debian 11, Asterisk® 19, and FreePBX® 16. So, if you pride yourself on your pioneering spirit, today’s your lucky day. When we’re finished, you’ll have the first ever Debian 11 platform running the latest releases of both Asterisk and FreePBX.


To get started, let’s first build a Debian 11 platform with Asterisk 18 and FreePBX 15. This is less bleeding edge technology which means better overall stability if you plan to put this into production. Download Debian 11 Minimal ISO from here. Or you can opt for a Debian 11 install at Vultr, Digital Ocean, CrownCloud, or RackNerd. Just follow the links on the Incredible PBX Wiki.

Once you have your Debian 11 platform up and running, log into your server as root using SSH and issue the following commands:

cd /root
wget http://incrediblepbx.com/IncrediblePBX2021-debian11.sh
chmod +x IncrediblePBX2021-debian11.sh
./IncrediblePBX2021-debian11.sh

Grab a cup of coffee and return in about 30 minutes. Once you reboot your server, you’ll be all set to begin your Incredible PBX adventure.

If you’d prefer to walk on the wild side, here’s how to upgrade your Debian 11 setup by installing the FreePBX 16 GPL modules and (optionally) Asterisk 19 in lieu of Asterisk 18 LTS:

cd /root
wget http://incrediblepbx.com/incrediblepbx2022-upgrade.tar.gz
tar zxvf incrediblepbx2022-upgrade.tar.gz
rm -f incrediblepbx2022-upgrade.tar.gz
./upgrade-to-IncrediblePBX2022

A prompt displays after the FreePBX 16 installation is finished and before the Asterisk 19 install begins. If you’d prefer to keep the Asterisk 18 LTS release on your server, press Ctrl-C.

Once the upgrade is finished, open the FreePBX GUI as admin and navigate to Admin -> Module Admin and remove the RestAPI module, upgrade and enable the SIPsettings module, and disable the Trunking module. Click the Apply Config button to load the changes.

From the Linux CLI, edit both php.ini files in /etc/php/7.4/cli and /etc/php/7.4/apache2. Uncomment the line that looks like this and change the 1000 value to 5000:

max_input_vars = 1000

Then restart Apache: systemctl restart apache2


You have probably noticed that the Incredible Fax components including HylaFax and AvantFax are not installed. Unfortunately, the Rocky 8 and Debian 11 platforms have broken the fax components. Don’t worry though. Somebody will appear out of nowhere and get things going again. So… stay tuned!

There are dozens of tutorials on the Incredible PBX Wiki to get you started if you’re new to all of this. Enjoy!

Oracle Cloud: Grab a Free Incredible PBX Cloud Server for Life

It’s not every day that you get an opportunity to deploy an Incredible PBX® server on a cloud platform as robust as the one offered by Oracle®. And the fact that it won’t cost you a dime EVER makes this all the more appealing. This isn’t some bargain basement, crippled cloud platform with barely enough horsepower to get your server booted. Quite the contrary. This is an ARM-based Ubuntu 20.04 platform with 6GB of RAM, 45+ GB of storage, and a 1GB network pipe. The CPU capacity is equivalent to multiple physical cores of an Intel Xeon processor with hyper threading enabled. The word you’re looking for is WOW! Our further testing suggests that, by deploying 1 OCPU instances, you can actually create 4 separate servers in your free allocation from Oracle. So let’s jump right in and get your new server up and running.

Getting Started with Oracle Cloud

For openers, you’ll need to set yourself up with a free Oracle Cloud account here. You can read all about Oracle’s Free Tier, and today we’ll be setting up an Always Free Ampere A1 Compute Resource which never expires. It provides 3,000 OCPU hours and 18,000 GB hours per month for free for VM instances using the VM.Standard.A1.Flex shape. For Always Free tenancies, this is equivalent to 4 OCPUs and 24 GB of memory. Translation: You can build an Asterisk® server to handle thousands of users with this platform. In fact, you can now build FOUR of them.

Once you’ve set up your account and accessed the Oracle Cloud Dashboard, click on the 3-bar Options Menu in the upper left column. You’ll be using two key options in the menus: Compute -> Instances and Networking -> Virtual Cloud Networks. We recommend you click the PIN icon on both of these so that they become available on your Home dashboard.


To begin, navigate to Identity -> Compartments and create a new incrediblepbx compartment. Then navigate to Compute -> Instances and click the Create Instance button. Accept the default Name and choose incrediblepbx as your Compartment. In the Image and shape section, click Edit. In the Image and Shape dialog, click the Change Image button and choose the Canonical Ubuntu 20.04 option. CAUTION: 22.04 is now the default so make sure you change it to 20.04 Image with the latest 20.04 Build Date! Next, click the Change Shape button and choose Virtual Machine, Ampere, check VM.Standard.A1.Flex) and select 1 OCPU with 6GB of RAM. In the Networking section, click Edit. Choose Public Subnet, Use network security groups to control traffic: No, Assign a public IPv4 address: Yes, and DNS record: Yes. Finally, in the Add SSH Keys section, leave the Generate a key pair for me option selected, and click Save Private Key then Save Public Key to download both keys to your desktop. Click Upload public key files (.pub) button and upload the Public Key you just downloaded into your instance. Finally, click the Create button to create your new instance. Once your instance is up and running, click on Public Subnet under Primary VNIC. In the Default Security List option, add Ingress and Egress Rules with an entry for Stateless=No, Source=0.0.0.0/0, IP Protocol=ALL, Source & Destination Port Range=ALL. In addition, add Ingress rules for UDP 5060:5069 and UDP 10000:20000. While appearing to be redundant, the UDP rules reportedly have been necessary to make and receive calls successfully.


Now copy the public IP address of your server which, together with your private key, you’ll need to login. From a Terminal window on your desktop PC, login to your server using the following commands where ssh-key-2022-05-24.key is the filename of your private key and 159.201.201.173 is the public IP address of your instance:

chmod 0600 ssh-key-2022-05-24.key
ssh -i ssh-key-2022-05-24.key ubuntu@159.201.201.173

Once you’re logged in, let’s configure the root account which you will need to install Incredible PBX. Begin by setting up a very secure password for root.

sudo passwd root
su root
cd ~
wget http://incrediblepbx.com/IncrediblePBX2021-Oracle.sh
chmod +x IncrediblePBX2021-Oracle.sh
./IncrediblePBX2021-Oracle.sh

We think you will find the performance is second to none. Here are our 1-OCPU results which far exceed the performance specs you’ll find at Vultr, Digital Ocean, or OVH on their 1-2 GB RAM platforms.


This is not a trivial install procedure so go have a long cup of coffee and return in about 40 minutes to press the ENTER key to kick off the Automatic Update Utility. Once that begins, you’ll need to press ENTER again in about 5 minutes when the updates are completed. Then your install will continue for a couple minutes when you will be prompted to press ENTER to reboot. Do so and you’re all set.

Managing Incredible PBX in the Oracle Cloud

All of the usual Incredible PBX features are available in the Oracle Cloud release. After rebooting, you now can login to your server as root using your root password. Be sure to login periodically so that the Automatic Update Utility is run to keep your server secure.

ssh -i ssh-key-2022-xx-xx.key ubuntu@public-IP-address
su root
cd ~
./update-IncrediblePBX



It’s also good practice to keep the FreePBX GPL modules up to date. Here’s how after logging in:

rm -f /tmp/*
fwconsole ma upgradeall
fwconsole reload
fwconsole restart
./sig-fix
./sig-fix

And don’t forget to…

Set your admin password for FreePBX GUI access: ./admin-pw-change

Set your admin password for Apache app access: ./apache-pw-change

Set your proper timezone: ./timezone-setup

Configure SendMail relay host: ./enable-gmail-smarthost-for-sendmail

Whitelist your IP addresses for access: ./add-ip and ./add-fqdn

Make a Backup and copy it off-site: ./incrediblebackup2021

Using Text-to-Speech Apps in the Oracle Cloud

Because the Oracle platform is ARM-based and most of the text-to-speech (TTS) apps are not, finding a TTS solution that actually worked was a challenge. But thanks to a tip from Dick Ollett, we’ve found a reliable alternative to PicoTTS. gTTS was easy to deploy with our existing applications and has restored the functionality of the Weather by ZIP Code (947) and News Headlines (951) applications using Incredible PBX on the Oracle Cloud platform.

Activating IBM Text-to-Speech for Oracle Cloud

IBM’s TTS offering still works reliably and, if you sign up for their LITE Pricing Plan, the first 10,000 characters per month are free. To get started, follow along in our previous IBM tutorial to sign up for service and the LITE TTS Pricing Plan which you will find by clicking on the Catalog tab in the toolbar, then choosing AI/Machine Learning, and then Text to Speech. Choose the Lite plan and make note of your API Key and access URL for the region you selected.

Next, log into your server as root and issue the following commands:

cd /var/lib/asterisk/agi-bin
wget http://incrediblepbx.com/ibmtts.tar.gz
tar zxvf ibmtts.tar.gz
rm -f ibmtts.tar.gz
./install-ibmtts-dialplan.sh

Finally, edit /var/lib/asterisk/agi-bin/ibmtts.php and insert your API Key and URL in the spaces provided. Then save the file.

Activating Amazon’s Polly TTS for Oracle Cloud

If you’d prefer to use Amazon’s Polly TTS, its pricing is incredibly reasonable, and the quality is second to none. For your first year of service, 5 million TTS characters a month are free. After that, the standard TTS cost is $4 per million characters per month prorated to actual usage. For example, with 300 TTS requests a month of 500 characters each, the monthly cost would be 60¢. We’ve previously documented the Polly TTS setup for Incredible PBX 2021 so you can follow that tutorial to deploy Polly TTS with Incredible PBX in the Oracle Cloud.

Using either service, you now should be able to obtain Weather Reports by ZIP Code by dialing 947 from any extension registered to your PBX. Get the latest News Headlines by dialing 951.

Deploying PicoTTS in the Oracle Cloud

Because Oracle Cloud runs on the ARM64 architecture, you’ll need the ARM64 version of PicoTTS:

cd /root
rm -f libttspico*
wget http://incrediblepbx.com/picotts-arm64.tar.gz
tar zxvf picotts-arm64.tar.gz
rm -f picotts-arm64.tar.gz
dpkg -i libttspico*

Activating OpenVPN Virtual Private Network

The OpenVPN Client software comes preinstalled with Incredible PBX. In order to activate OpenVPN, you simply need to copy your OpenVPN credentials to the server as /etc/incrediblepbx2021.ovpn. Then reboot. Your OpenVPN IP address will be shown in pbxstatus. For an overview of the OpenVPN setup procedure, read our original OpenVPN article. Then follow the simple steps on the Incredible PBX Wiki for OpenVPN Server and OpenVPN Client installs.

NOTE: Because of Oracle’s security zone policies, connecting extensions to your PBX using the public IP address may result in no audio on calls with some SIP clients. By connecting using the OpenVPN private IP address solves the problem in some cases.

Getting Started with Incredible Fax 2021

Believe it or not, there still are lots of folks that use faxes in their everyday lives. If you’re one of them, Incredible PBX has your back. Begin by logging into your server as root and running ./incrediblefax2021-ubuntu20.04.sh to install HylaFax and AvantFax on your server. You’ll be prompted a dozen or more times for information. Answer no to the secure fax question. For the rest of the prompts, just press ENTER to accept the default entries. Rebooting your server is required when the install finishes. Once your server is back on line, there will be a new AvantFax tab in the GUI. Before proceeding, be sure to set an Apache web apps password by running /root/apache-pw-change. Next, login to AvantFax with your browser. You first will be prompted for your Apache credentials. Enter admin for the username and whatever password you set up in the previous step. Then you will be prompted for your AvantFax credentials. The default is admin:password. After you enter the username and password, you will be prompted to change your admin password. The AvantFax dashboard then will display. If nothing has come unglued, you should see four green Idle icons:



You can Send Faxes from within AvantFax by choosing the Send Fax tab, or you can use one of many HylaFax clients. Google is your friend.

Configuring Inbound Routes for Fax Detection

Not all VoIP trunks support fax transmission, e.g. Vitelity. Assuming yours do and you’ll only know by trial and error, here’s how to configure FreePBX to automatically detect incoming faxes and process them for PDF delivery by email. First, make certain the Fax Configuration Module is enabled in Module Admin. Then, for each Inbound Route on which you wish to receive faxes, you’ll need to enable fax detection on each route.

Under the Fax tab of each Inbound Route, enter the following settings:

Detect Faxes: YES
Fax Detection Type: SIP
Fax Ring: YES
Fax Detect Time: 4
Fax Destination: Custom Destinations -> Fax (Hylafax)

To try things out, send yourself a fax at no cost in the U.S. from FaxZero.

Using the GraphQL API Tool with Incredible PBX

Begin by installing the required GraphQL components:

pip3 install --pre gql[all]

Next, open the FreePBX GUI and navigate to Connectivity -> API. Select the Scope Visualizer tab and check Read/Write for ALL GraphQL Modules. Then select the GraphQL Explorer tab and click Reload Explorer. In the GraphiQL dialog, enter the following and press the Start arrow to list all of your extensions:

query {
  fetchAllExtensions {
    status
    message
    totalCount
    extension {
      extensionId
    }
  }
}

For the complete tutorial on using GraphQL to list, edit, and populate virtually anything on your PBX, read this tutorial and review the Asterisk documentation for the GraphQL API.

Installing OPUS in the Oracle Cloud

Log into your server as root and issue the following commands:

rm /usr/lib64/asterisk/modules/codec_opus.so
rm /usr/lib64/asterisk/modules/codec_opus_open_source.so
rm /usr/lib64/asterisk/modules/res_format_attr_opus.so
rm /usr/lib/asterisk/modules/codec_opus.so
rm /usr/lib/asterisk/modules/format_ogg_opus*.so
rm /usr/lib/asterisk/modules/res_format_attr_opus.so
rm /usr/lib/asterisk/modules/codec_opus_open_source.so
cd /usr/lib64/asterisk/modules
wget http://incrediblepbx.com/opus-oracle.tar.gz
tar zxvf opus-oracle.tar.gz
rm opus-oracle.tar.gz
fwconsole restart
asterisk -rx "module show like opus"
asterisk -rx "core show translation paths opus"

How Sausage Is Made AND Special Thanks

While our name is associated with this build, I want to give a special tip of the hat to the important contributions from Dick Ollett on the text-to-speech deployment, Bill Simon on the CDR/CEL implementation with ODBC, and @knerd for his GraphQL tips. AArch64 is a different beast, and we couldn’t have pulled this off without their assistance. If you’re ever curious how sausage is actually made in the open source development world, you can read all about it in this VoIP-Info.org Forum thread. THANK YOU! Should you ever need paid Asterisk consulting, these are our two go-to guys. You can find them on the forum, or you can contact us for a referral.

Interconnecting Asterisk Servers with PJsip and OpenVPN


It’s been several years since we discussed interconnecting Asterisk® servers so today we want to do a version refresh using PJsip Trunking. We also want to show you how easy it is to secure the communications path by setting up the trunks using OpenVPN connections. When we’re finished, you’ll have a FREE way to call between sites using FreePBX® Outbound Routes. Because Incredible PBX comes preconfigured with all the components you’ll need, we’ll use that platform to further simplify the deployment. We’ll be interconnecting two Asterisk servers today, but you can use the same methodology to connect numerous sites.

Deploying OpenVPN with Asterisk Servers

To begin, you’ll want to get all of the sites configured with a virtual private network using OpenVPN. Our tutorial will walk you through the process. Keep in mind that all current releases of Incredible PBX are preconfigured to let you drop in your OpenVPN client credentials by naming them incrediblepbx.ovpn and copying the file into the /etc directory. Rebooting your server will bring up the virtual private network with a 10.8.0.x IP address.

Configuring PJsip Trunks on Your Asterisk Servers

If you remember yesteryear’s knuckle drill configuring SIP or IAX trunks for Asterisk connectivity, you’re in for a pleasant surprise using PJsip trunking with FreePBX. Using the GUI, create a new PJsip trunk for every site to which you want to establish a connection. A similar PJsip trunk must be created on the other site as well. If you’re just interconnecting two servers, then using the City locations for the Trunk Names will suffice. But, if there are more than two servers, specify unique names for each end of every PJsip connection, e.g.

NewYork1 <-> London1
NewYork2 <-> Washington1
NewYork3 <-> Miami1
London2 <-> Washington2
London3 <-> Miami2
Washington3 <-> Miami3

For today, we’ll interconnect a server in New York and London, but we’ll plan for the future and use London1 for the Trunk Name on the New York server and NewYork1 for the Trunk Name on the London server.

Let’s begin by configuring the London1 trunk on the New York server. After entering the London1 Trunk Name in the General tab, click on the pjsip Settings tab. In the General tab, leave the defaults in the first four fields. Then change the Registration field to None. For the SIP Server field, enter the OpenVPN IP address of the London server, e.g. 10.8.0.2. Because we’re using Incredible PBX, the PJsip port is 5061 so enter that in the SIP Server Port field. If you’re using a different flavor of FreePBX, enter the appropriate port number for PJsip on your platform. Next, click on the Advanced tab and enter the London server’s OpenVPN address in the Match (Permit) field, e.g. 10.8.0.2. In the Codecs tab, make note of the enabled codecs and make certain that the entries match on all of your servers. Click the Submit button to save your settings and then reload your dialplan.

Now let’s configure the NewYork1 trunk on the London server. After entering the NewYork1 Trunk Name in the General tab, click on the pjsip Settings tab. In the General tab, leave the defaults in the first four fields. Then change the Registration field to None. For the SIP Server field, enter the OpenVPN IP address of the New York server, e.g. 10.8.0.1. Because we’re using Incredible PBX, the PJsip port is 5061 so enter that in the SIP Server Port field. If you’re using a different flavor of FreePBX, enter the appropriate port number for PJsip on your platform. Next, click on the Advanced tab and enter the New York server’s OpenVPN address in the Match (Permit) field, e.g. 10.8.0.1. In the Codecs tab, make certain that the entries match those on your New York server. Click the Submit button to save your settings and then reload your dialplan. Here’s how it looks in the FreePBX GUI:


Use Outbound Routes to Interconnect Extensions

To keep things simple, let’s assume both your New York and London servers have extensions 701-705. To call an extension on the other server, we will simply dial 9 and then the 3-digit extension, e.g. dialing 9701 on the New York server will ring 701 on the London server and dialing 9701 on the London server will ring 701 on the New York server.

Create an Outbound Route on the New York server called London specifying London1 for the Trunk Sequence in the Route Settings tab. In the Dial Patterns tab, enter 9 in the Prefix field and XXX for the Match Pattern. Click Submit to save your settings and then reload dialplan.


Create an Outbound Route on the London server called New York specifying NewYork1 for the Trunk Sequence in the Route Settings tab. In the Dial Patterns tab, enter 9 in the Prefix field and XXX for the Match Pattern. Click Submit to save your settings and then reload dialplan.

If you’re interconnecting more than two sites, then you probably will want to designate a specific Prefix for every City so that users can travel between sites and use the same methodology to reach the same extensions from every location.

You can test things out using softphones by registering 701 to an extension in New York and another to the 701 extension in London. Now you can place secure and FREE calls between the sites by dialing 9701 from each softphone. Enjoy!

Migrating Incredible PBX 2022 to a PUBLIC-Facing Cloud PBX



Today we want to show you how to reconfigure Incredible PBX 2022 for Rocky 8 into a PUBLIC-facing Cloud PBX. What that means is authorized users can connect a SIP phone to the PBX regardless of where the user might be located without worries about an ever-changing dynamic IP address and the requirement to whitelist the new IP address. A PUBLIC-facing PBX also provides free SIP URI connectivity to users of your PBX by anyone from anywhere in the world. In other words, it’s similar to the way you could connect to any Ma Bell telephone in the world simply by knowing the number to dial. The difference, of course, is SIP URI connectivity is free while there were often staggering long distance charges for remote connectivity in the Ma Bell days. Fifty years ago it was not uncommon for a college boy to spend $200 a month calling his college sweetheart less than 200 miles away in the same state. Ask me how I know.

Why is this such a big deal? The short answer is security and your phone bill. You don’t want bad guys on the other side of the globe attempting to register a SIP phone to your PBX so that they can use your trunks to make free phone calls on your nickel. You also don’t want anybody and everybody calling your users by simply guessing the IP address of your PBX. As with Incredible PBX 2021 PUBLIC for Debian, today’s design combines several security mechanisms to make a PUBLIC-facing PBX safe and secure. First, we will block all SIP connectivity to your PBX by IP address. Second, we will identify 30,000+ known SIP bad guys and block their access to your PBX entirely. Third, we will only permit SSH access to your PBX using public key authentication instead of traditional username/password authentication. Fourth, we will only permit web access to the Incredible PBX portal from whitelisted IP addresses and OpenVPN private addresses. We haven’t mentioned the elephant in the room, Distributed Denial of Service (DDoS) attacks, but today’s methodology reduces the risk considerably since your PBX cannot be ping’d, and all IP address access is blocked at the Linux kernel level.

Prerequisites. To put all these safeguards in place, you’ll need a cloud-based Incredible PBX 2022 KVM platform running Rocky 8. Install the latest Incredible PBX 2022 platform using our tutorial. Next, you’ll need these items:

  1. Public IP Address of your server
  2. Obscure FQDN linked to this public IP address
  3. Random SSH port with registered public keys for SSH access
  4. List of SIP extensions to enable for SIP URI access
  5. IP Addresses to WhiteList for Access to the Web GUI

1. Deciphering Public IP Address of Your PBX

After logging into your PBX as root, you can execute pbxstatus to decipher the public IP address of the PBX. Or issue the command: wget -q -O - ipinfo.io/ip

2. Obtaining an FQDN for Your PBX

Security through obscurity provides a critical layer of protection for your server so choose an FQDN carefully. sip.yourname.com provides little protection while f246g.yourname.com pretty much assures that nobody is going to guess your domain name. This is particularly important with SIP registrations because registered extensions on your PBX can obviously make phone calls that cost you money. If you don’t have your own domain, you can always obtain a free hostname from a service such as NoIP.com.

3. Securing SSH Access to Your PBX

Whatever you do, don’t leave SSH access via port 22 exposed on your PBX. In the time it took to create a new PBX on CloudAtCost, there were over 400 attempted logins to the default SSH port of the new server. The simplest (but least secure) method to avoid these script kiddie attacks is to change the port number for SSH access to your server. We suggest using the year you were born as the port number because it’s easy to remember. Edit /etc/ssh/sshd_config and uncomment the Port line replacing 22 with the port number you chose. Then restart SSH: systemctl restart sshd.

The preferable solution to secure SSH is to create and use SSH keys for access and set PasswordAuthentication no on the last line of /etc/ssh/sshd_config. Digital Ocean has an excellent tutorial to walk you through the setup process.

4. Choosing Extensions for SIP URI Public Access

With today’s PUBLIC design, exposing an extension for PUBLIC access means anyone in the world that knows the FQDN of your server and the extension number can do two things using any SIP client: (1) they can call you and (2) they can attempt to register to that extension and make calls on your trunks AND your nickel. So only expose extensions for public access if there is a need to connect or call from remote locations. For extensions you decide to expose, make certain that the passwords for these extensions are extremely secure, lengthy, and use numbers with both UPPER and lower case letters. Never use default extension passwords!

5. Whitelisting IP Addresses for Public Web Access

Without enumerating IP addresses for public web access, you won’t be able to connect to the web GUI of your PBX from any IP address. Down the road, if you wish to authroize additional IP addresses, you can use /root/add-ip to add them via SSH.

Deploying Incredible PBX PUBLIC Firewall

To get started, log into your server as root and issue the following commands:

cd /tmp
wget http://incrediblepbx.com/newpublic.tar.gz
tar zxvf newpublic.tar.gz
rm -f newpublic.tar.gz

Next, edit /tmp/iptables.base and change the highlighted entries:


Change port 22 in the dport entry to the SSH port number you chose in Step 3, above.

Change 8.8.8.8, 8.8.4.4., and 1.1.1.1 to actual public IP addresses of desktop machines you wish to use to access the web GUI of your PBX. If you don’t need three entries, comment out the other entries with # at the beginning of each line.

Replace your-servers-IP-address with the actual IP address of your PBX from Step 1, above.

Save the file.

On the Rocky 8 platform, issue the following commands:

cd /etc/sysconfig
cp /tmp/iptables.base .
mv iptables iptables.orig
cp iptables.base iptables

Using Incredible PBX PUBLIC with Asterisk

The first line of defense with this PUBLIC implementation is your FQDN. Second is the IPtables firewall setup above. And third is the Asterisk® extensions configuration in extensions_override_freepbx.conf. Here’s how to configure it. Edit /tmp/extensions_override_freepbx.base and change the highlighted entries:


If there are phone numbers assigned to your PBX that you want processed according to your Inbound Routing rules, duplicate the first highlighted line above and, for each trunk, replace 8881234567 with your actual DID numbers.

In exten => _.,1 line, replace your-servers-IP-address with the actual IP address of your PBX from Step 1, above.

In exten => _.,10 line, replace your-servers-FQDN with the actual FQDN assigned to your PBX from Step 2, above.

Scroll down in the file to the following section:



Comment out undesired default extensions. Place a semicolon at the beginning of the lines.

For any extensions you wish to add, insert a new line in the following format replacing both 7000 entries with the desired extension number:

exten => 7000,13,Dial(local/7000@from-internal)

Save the file and then execute the following commands to complete the PUBLIC setup:

cd /etc/asterisk
cp /tmp/extensions_override_freepbx.base .
mv extensions_override_freepbx.conf extensions_override_freepbx.orig
cp extensions_override_freepbx.base extensions_override_freepbx.conf
fwconsole restart
asterisk -rx "dialplan reload"
iptables-restart
sed -i 's|-A INPUT|-I INPUT|' /root/add-ip
sed -i 's|-A INPUT|-I INPUT|' /root/add-fqdn

Adding IPSET Incredible PBX 2022 Protection

We’re not the biggest fans of blacklists because the bad guys spend a lot of time trying to corrupt them by inserting valid IP addresses of sites such as DNS servers in the lists to wreak havoc. Having said that, there are two blacklists that are carefully monitored on a daily basis, and both provide additional protection for your PBX by weeding out access by 30,000+ potential bad guys. The oldest of these is VoIP Blacklist. And the new kid on the block is APIBAN from LOD.com and Fred Posner. We’ve simplified the setup process for use with Incredible PBX 2022. To get started, obtain an APIBAN API key here. Then issue the following commands to put all the pieces in place on your server:


cd /usr/local/sbin
wget http://incrediblepbx.com/incrediblepbx-ipsets8.tar.gz
tar zxvf incrediblepbx-ipsets8.tar.gz
rm -f incrediblepbx-ipsets8.tar.gz

Next, edit /usr/local/sbin/apiban-init and insert your APIkey.

Finally, issue the following command to reload the firewall: iptables-restart

Verifying Firewall Setup of Incredible PBX

Let’s make certain that everything got installed correctly. Begin by issuing this command: iptables -nL

Scroll toward the top of the list, and you should see two entries for the voipbl and apiban ipsets indicating that entries in those lists will be dropped by the firewall.


Next, verify that the voipbl and apiban ipsets are populated. The first two commands below will list all of the blocked IP addresses. And the next two commands will provide a count of the dropped IP addresses.

ipset list voipbl
ipset list apiban
ipset list voipbl | wc -l
ipset list apiban | wc -l

Finally, you can refresh the ipsets with the following two commands:

voipbl-init
apiban-init

Rebooting or restarting the firewall with iptables-restart also refreshes the ipset listings.




 

Calling an Incredible PBX PUBLIC Extension

Any extensions that you have whitelisted in the blue section above can be called from anywhere using any SIP client. Simply enter the SIP URI for the extension in the following format: SIP/extension@your-servers-FQDN

CAUTION: If a caller attempts to call any extension on your PUBLIC server from an extension on another Asterisk server to which the caller is registered, the call will fail if there is a matching extension number on the PUBLIC server and the two servers are not registered to each other. So remember to use unique extension numbers on your PUBLIC server if you expect callers from other Asterisk servers.

Registering Incredible PBX PUBLIC Extension

If you wish to login to a whitelisted extension using a SIP client, enter the extension and password of the extension. For the server address, enter the FQDN of your server. If it’s a PJsip extension, add :5061 to the end of the FQDN.

5 Minute Wonder: Incredible PBX 2022 in Cloud for $25/Yr.



We’ve been building turnkey Incredible PBX® servers for virtual machine platforms for many years. Because the servers are built from images, typical install times have been 5 minutes or less with Proxmox, VirtualBox, and VMware ESXi. But the missing piece has been a similar image install on a true cloud-based platform. This limitation was primarily due to the fact that we don’t own or control the available cloud platforms which typically limit image installs to operating systems such as CentOS, Debian, Ubuntu, and Windows. However, CrownCloud was good enough to add our Incredible PBX 2021 Debian image and the Incredible PBX 2020 CentOS 7 image to their portfolio. And, today, we have more good news. CrownCloud has now added the Incredible PBX 2022 image for Rocky 8 as well.

These 5-minute turnkey installs of Incredible PBX 2020 for CentOS 7, Incredible PBX 2021 for Debian 10, and now Incredible PBX 2022 for Rocky 8 are being offered at the jaw-dropping price of $25 a year. The monthly cost is cheaper than a cup of coffee at Starbucks, and you’ll have a fully-functioning, production-ready KVM platform including a free snapshot with 1GB RAM, 20GB SSD storage, and 1TB of monthly bandwidth in your choice of server locations including Los Angeles and Atlanta in the United States as well as Germany and the Netherlands in Europe. And, unlike all of the other Asterisk® aggregations, Incredible PBX still provides a source code-based platform that can be tailored to meet any special requirements your organization may need.

We don’t make a nickel on these offerings so consider this our special thanks to all of our loyal fans.

Here are the links to sign up for the service and take advantage of these Incredible PBX deals:

When you sign up for the service, choose any traditional OS for the base install. Once it’s on line, go into CrownPanel and choose Reinstall. Then select Incredible PBX 2022 for Rocky from the Application Images pulldown as your new install. In less than 5 minutes, your server will be ready for you to login. Be sure to use SSH and NOT the VNC utility included in CrownPanel. This will assure that your desktop machine’s IP address gets whitelisted in the Incredible PBX firewall. Otherwise, you won’t be able to SSH into your server from your desktop. Once you login, the Incredible PBX configurator will prompt you to set passwords for root login, admin login to FreePBX, and admin login credentials for Apache to access AsteriDex and Reminders. Add a trunk provider (Skyetel is preconfigured and enabled by default) and a softphone or Incredible PBX SIP phone, and your PBX is fully operational. Check out the CrownCloud Wiki.


Planning Ahead for That Rainy Day

One of our favorite features of Crown Cloud is the free snapshot (a.k.a. backup) at no additional charge. We recommend you take snapshots regularly as you make major changes in your server’s configuration. In this way, if something comes unglued, you can easily restore the snapshot and never miss a beat. You’ll find the Remote Snapshot option in your CrownPanel menu.

Configuring Skyetel for Incredible PBX

If you’ve decided to go with Skyetel, here’s the drill. Sign up for Skyetel service and take advantage of the Nerd Vittles specials. First, complete the Prequalification Form here. You then will be provided a link to the Skyetel site to complete your registration. Once you have registered on the Skyetel site and your account has been activated, open a support ticket and request the $10 credit for your account by referencing the Nerd Vittles special offer. Once you are satisfied with the service, fund your account as desired, and Skyetel will match your deposit of up to $250 simply by opening another ticket. That gets you up to $500 of half-price calling. Credit is limited to one per person/company/address/location. Effective 10/1/2023, $25/month minimum spend required.

Skyetel does not require SIP registrations to make connections to your PBX. Instead, Skyetel can use Endpoint Groups to identify which servers can communicate with the Skyetel service. An Endpoint Group consists of a Name, an IP address, a UDP or TCP port for the connection, and a numerical Priority for the group. For incoming calls destined to your PBX, DIDs are associated with an Endpoint Group to route the calls to your PBX. For outgoing calls from your PBX, a matching Endpoint Group is required to authorize outbound calls through the Skyetel network. Thus, the first step in configuring the Skyetel side for use with your PBX is to set up an Endpoint Group. Here’s a typical setup for Incredible PBX:

  • Name: MyPBX
  • Priority: 1
  • IP Address: PBX-Public-IP-Address
  • Port: 5060
  • Protocol: UDP
  • Description: my.incrediblepbx.com

To receive incoming PSTN calls, you’ll need at least one DID. On the Skyetel site, you acquire DIDs under the Phone Numbers tab. You have the option of Porting in Existing Numbers (free for the first 60 days after you sign up for service) or purchasing new ones under the Buy Phone Numbers menu option.

Once you have acquired one or more DIDs, navigate to the Local Numbers or Toll Free Numbers tab and specify the desired SIP Format and Endpoint Group for each DID. Add SMS/MMS and E911 support, if desired. Call Forwarding and Failover are also supported. That completes the VoIP setup on the Skyetel side. System Status is always available here. Everything is already in place on the Incredible PBX 2022 side of the house so you can start making and receiving calls immediately.

Configuring ClearlyIP SIP Trunking

For the tightest integration with FreePBX, no SIP provider holds a candle to Incredible PBX SIP Trunking with ClearlyIP. The reason is fairly obvious. The ClearlyIP folks were the original developers of FreePBX. In addition to all of the traditional SIP trunking services, you also get CNAM support and state-of-the-art E911 service which can be deployed in full compliance with Kari’s Law and the Ray Baum Act. If you’re a system integrator and don’t know about your financial liability for failure to comply with the new rules, it’s time to do some reading.

Configuring VoIP.ms for Incredible PBX

To sign up for VoIP.ms service, may we suggest you use our signup link so that Nerd Vittles gets a referral credit for your signup. Once your account is set up, you’ll need to set up a SIP SubAccount and, for Authentication Type, choose Static IP Authentication and enter your Incredible PBX server’s public IP address. For Transport, choose UDP. For Device Type, choose Asterisk, IP PBX, Gateway or VoIP Switch. Order a DID in their web panel, and then point the DID to the SubAccount you just created. Be sure to specify atlanta1.voip.ms as the POP from which to receive incoming calls. In the Incredible PBX GUI, be sure to enable the VoIP.ms trunk.

Configuring Anveo Direct for Incredible PBX

To sign up for Anveo Direct service, sign up on their web site and then login. After adding funds to your account, purchase a DID under Inbound Service -> Order DID. Next, choose Configure Destination SIP Trunk. Give the Trunk a name. For the Primary SIP URI, enter $[E164]$@server-IP-address. For Call Options, select your new DID from the list. You also must whitelist your public IP address under Outbound Service -> Configure. Create a new Call Termination Trunk and name it to match your server. For Dialing Prefix, choose six alphanumeric characters beginning with a zero. In Authorized IP Addresses, enter the public IP address of your server. Set an appropriate rate cap. We like $0.01 per minute to be safe. Set a concurrent calls limit. We like 2. For the Call Routing Method, choose Least Cost unless you’re feeling extravagant. For Routes/Carriers, choose Standard Routes. Write down your Dialing Prefix and then click the Save button.

Before you can make outbound calls through Anveo Direct from your PBX, you first must configure the Dialing Prefix that you wrote down in the previous step. Log into the GUI as admin using a web browser and edit the Anveo-Out trunk in Connectivity -> Trunks. Enable the Trunk. Then click on the custom-Settings tab and replace anveo-pin with your actual Dialing Prefix. Click Submit and Apply Config to complete the setup. In the Incredible PBX GUI, be sure to enable all of the remaining Anveo trunks.

By default, incoming Anveo Direct calls will be processed by the Default inbound route on your PBX. If you wish to redirect incoming Anveo Direct calls using DID-specific inbound routes, then you’ve got a bit more work to do. In addition to creating the inbound route using the 11-digit Anveo Direct DID, enter the following commands after logging into your server as root using SSH/Putty:

cd /etc/asterisk
echo "[from-anveo]" >> extensions_custom.conf
echo "exten => _.,1,Ringing" >> extensions_custom.conf
echo "exten => _.,n,Goto(from-trunk,\\${SIP_HEADER(X-anveo-e164)},1)" >> extensions_custom.conf
asterisk -rx "dialplan reload"

Configuring a SIP Phone for Incredible PBX 2022

We’re in the home stretch now. You can connect virtually any kind of telephone to your new PBX. Plain Old Phones require an analog telephone adapter (ATA) which is a standalone SIP device such as ObiHai’s OBi100 or OBi110 (if you have a phone line from Ma Bell to hook up as well). SIP phones can be connected directly so long as they have an IP address. We obviously recommend the Incredible PBX IP phones from ClearlyIP which are the most versatile.

If you’ve been keeping up with recent Nerd Vittles developments, then you already know that we have just introduced a new Cellular Phone which connects directly to your PBX and serves as a perfect remote extension and traveling companion. You can read all about it here.

Software devices such as the YateClient softphone are another option for desktop machines. We’ll start with a free one today so you can begin making calls. You can find dozens of recommendations for hardware-based SIP phones both on Nerd Vittles and the VoIP-Info.org Forum when you’re ready to get serious about VoIP telephony.

We recommend YateClient for Windows which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 701 extension on Incredible PBX. You can find them by running /root/show-passwords. You’ll need the IP address of your server plus your extension 701 password. In the YateClient, fill in the blanks using the IP address of your Server plus :5061 for the PJsip 701 extension, 701 for your Username, and whatever Password was assigned to the extension when you installed Incredible PBX. Click OK to save your entries.

Once you are registered to extension 701, close the Account window. Then click on YATE’s Telephony Tab and place some test calls to the numerous apps that are preconfigured on Incredible PBX. Dial a few of these to get started:

DEMO - Apps Demo
123 - Reminders
947 - Weather by ZIP Code
951 - Yahoo News
TODAY - Today in History
LENNY - The Telemarketer's Worst Nightmare

If you are a Mac user, another great no-frills softphone is Telephone. Just download and install it from the Mac App Store. For Android users, check out the terrific new VitalPBX Communicator. Works flawlessly with Incredible PBX.

For smartphone solutions, visit the Incredible PBX Wiki for our softphone recommendations.

Configuring SendMail with Incredible PBX

In order to receive voicemails by email delivery, outbound mail functionality from your server obviously is required. We strongly recommend configuring SendMail using either your ISP or Gmail as an SMTP Relay Host. NOTE: If you are using a Gmail account with 2-step verification enabled, you MUST use a Gmail App Key instead of your Gmail account password. You also must enable Less Secure Apps access to the Gmail account.

Configuring a Gmail account with Incredible PBX 2022 is as simple as entering your Gmail credentials. Just run this script: /root/enable-gmail-smarthost-for-sendmail.

Here are the steps using a Gmail account with Incredible PBX 2020:

cd /etc/mail
yum -y install sendmail-cf
hostname -f > genericsdomain
touch genericstable
cd /usr/bin
rm -f makemap
ln -s ../sbin/makemap.sendmail makemap
cd /etc/mail
makemap -r hash genericstable.db < genericstable
mv sendmail.mc sendmail.mc.original
wget http://incrediblepbx.com/sendmail.mc.gmail
cp sendmail.mc.gmail sendmail.mc
mkdir -p auth
chmod 700 auth
cd auth
echo AuthInfo:smtp.gmail.com \\"U:smmsp\\" \\"I:user_id\\" \\"P:password\\" \\"M:PLAIN\\" > client-info
echo AuthInfo:smtp.gmail.com:587 \\"U:smmsp\\" \\"I:user_id\\" \\"P:password\\" \\"M:PLAIN\\" >> client-info
echo AuthInfo:smtp.gmail.com:465 \\"U:smmsp\\" \\"I:user_id\\" \\"P:password\\" \\"M:PLAIN\\" >> client-info
# Stop here and edit client-info (nano -w client-info) in all three lines.
# Replace  user_id with your gMail account name without @gmail.com
# Replace password with your real gMail password OR
#  use your Gmail App Key if 2-step verification is enabled
# Be sure to replace the double-quotes shown above if they don't appear in the file!!!
# Save your changes (Ctrl-X, Y, then Enter)
chmod 600 client-info
makemap -r hash client-info.db < client-info
cd ..
make
systemctl restart sendmail

Even though these servers are hosted in the cloud, we still recommend using a SmartHost to minimize email delivery problems.

Test outbound mail using this command with your actual email address:

echo "test" | mail -s testmessage yourname@youremaildomain.com

On some implementations, you may notice in the FreePBX GUI that the mail queue has failed. Here's the fix:

chmod 777 /var/spool/mqueue
service sendmail restart

Once you are sure your emails are being delivered reliably, here's a sample GUI voicemail configuration for an extension:



Be advised that Google has hinted that the Gmail Smarthost landscape may be changing. See our recent article for a simple SmartHost alternative.

Incredible PBX Administration

We've eased the pain of administering your new PBX with a collection of scripts which you will find in the /root folder after logging in with SSH or Putty. Here's a quick summary of what each of the scripts does.

add-fqdn is used to whitelist a fully-qualified domain name in the firewall. Because Incredible PBX blocks all traffic from IP addresses that are not whitelisted, this is what you use to authorize an external user for your PBX. The advantage of an FQDN is that you can use a dynamic DNS service to automatically update the IP address associated with an FQDN so that you never lose connectivity.

add-ip is used to whitelist a public IP address in the firewall. See the add-fqdn explanation as to why this matters.

del-acct is used to remove an IP address or FQDN from the firewall's whitelist.

admin-pw-change is used to set the admin password for access to the FreePBX/Incredible PBX web GUI using a browser pointed to the local IP address of your server.

apache-pw-change is used to set the admin password for access to Apache/Incredible PBX apps including AsteriDex and Reminders. This provides a password layer of protection for access to these applications.

reset-conference-pins is a script that automatically and randomly resets the user and admin pins for access to the preconfigured conferencing application. Dial C-O-N-F from any registered SIP phone to connect to the conference.

reset-extension-passwords is a script that automatically and randomly resets ALL of the SIP passwords for extensions 702-705. Be careful using this one, or you may disable existing registered phones and cause Fail2Ban to blacklist the IP addresses of those users. HINT: You can place a call to the Ring Group associated with all five extensions by dialing 777.

reset-reminders-pin is a script that automatically and randomly resets the pin required to access the Telephone Reminders application by dialing 123. It's important to protect this application because a nefarious user could set up a reminder to call a number anywhere in the world assuming your SIP provider's account was configured to allow such calls.

show-feature-codes is a cheat sheet for all of the feature codes which can be dialed from any registered SIP phone. It documents how powerful a platform Incredible PBX actually is. A similar listing is available in the GUI at Admin -> Feature Codes.

show-passwords is a script that displays most of the passwords associated with Incredible PBX. This includes SIP extension passwords, voicemail pins, conference pins, telephone reminders pin, and your Anveo Direct outbound calling pin (if configured). Note that voicemail pins are configured by the user of a SIP extension the first time the user accesses the voicemail system by dialing *97.

ssh-regen.sh allows you to reset the SSH keys for your server for added security.

update-IncrediblePBX is the Automatic Update Utility which checks for server updates from incrediblepbx.com every time you log into your server as root using SSH or Putty. Do NOT disable it as it is used to load important fixes and security updates when necessary. We recommend logging into your server at least once a week.

pbxstatus (shown above) displays status of all major components of Incredible PBX.

Forwarding Calls to Your Cellphone. Keep in mind that inbound calls to your DIDs automatically ring all five SIP extensions, 701-705. The easiest way to also ring your cellphone is to set one of these five extensions to forward incoming calls to your cellphone. After logging into your PBX as root, issue the following command to forward calls from extension 705 to your cellphone: asterisk -rx "database put CF 705 6781234567"

To remove call forwarding: asterisk -rx "database del CF 705"

Keeping FreePBX 15 Modules Current

We strongly recommend that you periodically update all of your FreePBX modules to eliminate bugs and to reduce security vulnerabilities. From the Linux CLI, log into your server as root and issue the following commands:

rm -f /tmp/*
fwconsole ma upgradeall
fwconsole reload
/root/sig-fix
/root/sig-fix
