The Most Versatile VoIP Provider: FREE PORTING

Introducing OSS Endpoint Manager for FreePBX 16 & Incredible PBX 2027


If you’ve been searching for a free, open source provisioning system for your SIP telephones and you’re using Incredible PBX 2027 or other FreePBX® 16 platforms, your prayers have been answered thanks to the hard work of Bill Simon. What this buys you (for free) is a quick way to configure SIP devices from most of the major players shown above including Aastra, AudioCodes, Cisco, Linksys, CloudTC, Digium, Grandstream, Intelbras, Mitel, Norphonic, Patton, Polycom, Snom, Thomson, Unidata, Xorcom, and Yealink.

To get started, log into FreePBX on your PBX platform and click on the Settings tab. If you see OSS Endpoint Manager as you will on most Incredible PBX 2027 installations, you can skip installing OSS Endpoint Manager and move on to the next step. Otherwise, here are the steps to install OSS EPM 16. Using SSH, log into your PBX as root and issue the following commands:

cd /var/www/html/admin/modules
wget https://filedn.com/lBgbGypMOdDm8PWOoOiBR7j/OSS-EPM/ossepm16.tgz
tar zxvf ossepm16.tgz
fwconsole ma install endpointman
rm -f /tmp/*
fwconsole reload 

Once you have OSS Endpoint Manager installed, return to the FreePBX GUI and open the application under the Settings tab. Read the reminder that you’re not using Sangoma’s commercial endpoint management product. Then click on the pull-down box in the right margin. Now let’s get the templates for the various SIP devices loaded onto your server.

  1. On the right pull-down, choose EndPoint Manager Settings.
  2. Adjust the entries as desired to set up your server as the host.
  3. For Package Server, enter: https://ossepm.incrediblepbx.com/
  4. Click in any other field to save your entries.
  5. On the right pull-down, choose Template Manager.
  6. Click the displayed link to download the latest templates from GitHub.
  7. On the right pull-down, choose Package Manager.
  8. Click Check for Updates.
  9. Click Install button beside each desired Brand.


The rest is a walk in the park. Plug in your SIP devices and perform the manufacturer’s steps to place the device in configuration mode. Insert the credentials to access OSS EPM on your PBX. Then sit back and enjoy the show.

Incredible ChatGPT: Artificial Intelligence For Your Phone



Unless you’ve been sleeping under a rock, you already know that Artificial Intelligence (AI) has the potential to transform every aspect of our lives. The reasons are fairly obvious. AI can process and analyze massive amounts of data in seconds that humans could spend months and years collecting. AI is being used to develop new drugs and treatments, diagnose diseases, and provide personalized care to patients. It’s being used to develop self-driving cars and trucks, optimize traffic flows, and improve public transportation. It can be used in manufacturing to automate tasks, improve quality control, and reduce costs. And AI can be used in the financial world to detect fraud, assess risk, and make investment decisions. Because of AI’s encyclopedic prowess, it can also write a mean term paper with human-like prose. That’s the good news. The bad news is that not everything AI regurgitates is accurate so be extremely careful relying upon AI exclusively to make decisions. See if you can spot the problem in this ChatGPT response:
 


ChatGPT is a large language model chatbot developed by OpenAI, a company backed by Microsoft®. Within two months after launch, ChatGPT had over 100 million subscribers. It is trained on a massive dataset of text and code and is able to generate human-like text, translate languages, write different kinds of creative content, and answer your questions in an informative way. The knowledge cutoff date for the gpt-3.5-turbo version of ChatGPT is September 2021. For users of Incredible PBX, today we’re pleased to bring that ChatGPT model to a telephone near you.

To get started, you’ll need three components. First, you’ll need an Incredible PBX 2027 platform with Debian 11 or Ubuntu 22.04 running on Windows, a Mac, or Linux. Turnkey versions are available for dozens of virtual machine and cloud-based platforms. If you’re using Incredible PBX 2027 on the Rocky 8 platform, you will also need to install the gTTS text-to-speech engine from here. Second, you’ll need to obtain a free OpenAI_KEY here using your Google, Apple, or Microsoft email account. And, third, you’ll need to obtain a free Speech-to-Text API_KEY and API_URL from IBM. Once you have the three pieces in hand, you’re ready to proceed with the installation for your Incredible PBX platform. After installation, you can make ChatGPT queries using any telephone connected to your PBX. Simply dial 2428 (C-H-A-T) and speak your query.

Installing the ChatGPT Telephone Interface

Not every ChatGPT response is suitable for use with a telephone. You wouldn’t want ChatGPT reading you a term paper or spouting out some Asterisk® dialplan code. Nor can most telephones display photos. So our deployment for Incredible PBX today provides two ChatGPT solutions: (1) a command-line interface that is accessible from a terminal or via SSH: chatgpt -p "your query". (2) The telephone interface is accessible by dialing 2428. For the telephone interface, be careful what you ask. You don’t want a 10,000-word response. For example, a good query might be "What are the five best Atlantic coast beaches in the United States." A not-so-good query would be "What are the best restaurants in the world."

To get started after installing Incredible PBX using one of the numerous tutorials available here, log into your server as root and issue the following commands:

cd /
wget https://filedn.com/lBgbGypMOdDm8PWOoOiBR7j/ChatGPT/incredible-chat.tar.gz
tar zxvf incredible-chat.tar.gz
cd /root

Once the components have been downloaded and installed, navigate to the /root folder.
Enter your ChatGPT and IBM STT credentials in the following files:

  • Edit chat and insert your OPENAI_KEY in line 6
  • Edit chatgpt and insert your OPENAI_KEY in line 15
  • Edit chatgpt.sh and insert your OPENAI_KEY in line 12
  •  Also insert your IBM STT API_KEY in line 16 of chatgpt.sh
  •  Also insert your IBM STT API_URL in line 17 of chatgpt.sh

Complete the install by issuing the following commands:

cd /root
sed -i '/\[from-internal-custom\]/r chat.code' /etc/asterisk/extensions_custom.conf
chmod +x chat*
mv chat /usr/local/sbin
mv chatgpt /usr/local/bin
mv chatgpt.sh /var/lib/asterisk/agi-bin
asterisk -rx "dialplan reload"

NOTE: The chatgpt command-line tool does not work on the Rocky 8 platform because of a bug in their fold implementation. However, both our chat command-line tool and the 2428 telephony interface work fine once the gTTS text-to-speech engine is installed for Rocky 8.

Making a Test Call with ChatGPT

Now that all the pieces are in place, let’s make a test call. From a phone connected to your Incredible PBX server, dial 2428. At the prompt, enter the following query: What Are the Five Best Gulf Coast Beach Resorts in the United States? Within a minute or so, ChatGPT will provide the answer using the gTTS text-to-speech engine included in Incredible PBX. Enjoy!

A Cautionary Note About ChatGPT

We’ll close today with this cautionary note about ChatGPT… from ChatGPT:

Faxing Returns for Incredible PBX 2027 Platforms



As you may know, the introduction of Rocky 8, Debian 11, Ubuntu 22.04, and PHP 7.4 blew our HylaFax/AvantFax/IAXmodem faxing solution out of the water leaving all of the Incredible PBX 2027 builds with no fax capabilities. With some tips from our long-time contributor, Bill Simon, we are happy to report that an alternative solution is now available. It now provides BOTH incoming and outgoing fax support with email PDF delivery of all received faxes. While there are numerous free and paid options that support Outbound Faxing, we now have added an easy-to-use script that provides this functionality on Incredible PBX 2027 platforms.

Inbound Faxing Solution with Incredible PBX 2027

The new inbound faxing solution works much like it did with HylaFax and IAXmodem. You configure your Inbound Routes in FreePBX® to listen for fax tones. When an incoming fax is detected, the call is transferred to a SpanDSP fax context in Asterisk®. The incoming fax is then recorded as a .tiff image. When the recording is finished, we use the TIFF2PDF application to convert the image to a PDF file which is then emailed to a designated email address which you configure as part of this fax setup procedure. The prerequisite, of course, is to assure that Incredible PBX 2027 can send emails. This was covered in the initial setup tutorials, but we will repeat it below for slow learners.

Let’s first get your Incredible PBX 2027 platform configured to detect and process incoming fax calls. Log into your server as root and issue the following commands.

1. For Rocky 8 platforms: yum install libtiff && yum install libtiff-tools
    For Debian, Ubuntu, and Raspberry Pi platforms: apt install libtiff-tools -y

2. Issue the following commands to put the inbound fax context in place:

sed -i '/^\[custom-fax/,/^$/d' /etc/asterisk/extensions_custom.conf
echo '
[ext-group](+)
exten => fax,1,Noop(Fax detected)
exten -> fax,2,Goto(custom-fax-iaxmodem,s,1)

[custom-fax-iaxmodem]
exten => s,1,Answer
exten => s,n,Wait(1)
exten => s,n,Verbose(3,Incoming Fax)
exten => s,n,Set(FAXEMAIL=)     ; fax email address of recipient
exten => s,n,Set(FAXDEST=/tmp)  ; folder where faxes will be stored
exten => s,n,Set(tempfax=${STRFTIME(,,%C%y%m%d%H%M)})
exten => s,n,ReceiveFax(${FAXDEST}/${tempfax}.tif)
exten => s,n,System(/usr/bin/tiff2pdf -o "${FAXDEST}/${tempfax}.pdf" "${FAXDEST}/${tempfax}.tif")
exten => s,n,System(/usr/bin/echo "Incoming fax is attached." | /usr/bin/mail -s "Incoming FAX  Received" -A "${FAXDEST}/${tempfax}.pdf" "${FAXEMAIL}")
exten => s,n,Hangup

' >> /etc/asterisk/extensions_custom.conf

3. Update the fax context to include your email address for delivery of inbound faxes. Insert your email address in the code below replacing yourname@gmail.com:

sed -i 's|FAXEMAIL=|FAXEMAIL=yourname@gmail.com|' /etc/asterisk/extensions_custom.conf

4. Download and install the Fax module for FreePBX:

fwconsole ma downloadinstall fax
rm /tmp/*
fwconsole reload

5. Open the FreePBX GUI and check to be sure you still have a Custom Destination called Fax (HylaFax). If not, create it:

Target: custom-fax-iaxmodem,s,1
Description: Fax (HylaFax)
Return: No

6. In the FreePBX GUI, modify each of your Inbound Routes to support incoming faxes from the DIDs you’ll be using for inbound faxes. In the new Fax tab, edit the settings as shown below, save the settings, and reload your dialplan.

 Yes
 SIP
 No
 5
 Custom Destinations
  Fax (HylaFax)

7. Be sure you have configured Outbound Email with SendMail using the instructions below before continuing.

8. Send a test fax from FaxZero to one of your fax-enabled DID’s while watching the Linux CLI for issues.


Configuring Gmail as Smart Relay Host

Most Incredible PBX implementations will be on networks managed by companies like Comcast, Spectrum, and AT&T that block downstream mail servers (that’s you) from sending email. The solution is to use Gmail or your local ISP as a smart relay host to send mail from your server. You’ll need this to deliver voicemails and faxes via email. Here’s how to set it up using a Gmail account.

IMPORTANT: You MUST obtain and use a Gmail App Password instead of your Gmail account password when running the script below. If you’re a Google hater, here’s an alternative.

/root/enable-gmail-smarthost-for-sendmail

Now send yourself a test email message to make sure things are working properly:

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

Outbound Faxing Solutions with Incredible PBX 2027

We’ve now developed a sendfax.sh script for use on Incredible PBX 2027 platforms. It lets you send any PDF document as a fax by simply copying the file to the /tmp directory and running the sendfax.sh script. You’ll be prompted for the name of the PDF file to send, the trunk to use for the call, and the phone number of the destination fax in the format required by your designated trunk. Make certain that you have provided the appropriate CallerID number in your Trunk setup, or the outbound calls may fail. After you complete the steps above to enable Inbound Faxing, issue the following commands to install this new Outbound Faxing addition:

cd /root
wget http://incrediblepbx.com/sendfax2027.tar.gz
tar zxvf sendfax2027.tar.gz
rm -f sendfax2027.tar.gz

Now let’s be sure your platform has the necessary components to support Outbound Faxing.

On Rocky 8 platforms, issue the following commands:

yum install libtiff
yum install libtiff-tools
yum install ghostscript

On Debian, Ubuntu and Raspberry Pi platforms, issue the following commands:

 apt update
 apt install libtiff-tools -y
 apt install ghostscript -y
 

Next edit /root/sendfax.sh and enter the callerid, faxheader, and faxstationid for your new Outbound Faxing Engine.

Disable the messages prompting for these components by issuing the command:
touch /etc/pbx/.sendfax

Finally, for installs before 9/27/2023, if you will be using a PJsip trunk to send outbound faxes, issue the following command to adjust the syntax in the sendfax.sh script. This is automatic for new installs.

sed -i 's|SIP/$mytrunk/$faxnumber|PJSIP/$faxnumber@$mytrunk|' /root/sendfax.sh

Now you’re ready to take Outbound Faxing for a test drive. Deposit a PDF file in the /tmp directory of your server. Then issue the following command to begin the Outbound Faxing process: /root/sendfax.sh. When prompted, enter the file name of your PDF file, the trunk name which will be used to make the call, and the phone number for the fax destination. That’s all the setup that’s required.

When you run the script, it will stay active until the fax has been delivered in order to alert you as to whether the fax transmission was successful. If, for some reason, the fax transmission fails, you can resend it with the following commands:

cp -ap /root/sendfax.call /tmp/cf
rm -f /var/spool/asterisk/outgoing_done/cf
mv /tmp/cf /var/spool/asterisk/outgoing/

You can verify receipt of the new fax attempt by waiting a reasonable time and then issuing these commands:

cd /var/spool/asterisk/outgoing_done
date -d @`cat cf | grep StartRetry | cut -f 2 -d "(" | cut -f 1 -d ")"`
cat cf | grep Status


While it is no longer possible to send faxes directly using AvantFax, there are some additional alternatives. A free one is faxzero.com, which lets you send 5 free faxes a day with up to 3 pages of text plus a cover sheet. A second alternative for infrequent use is to pay FaxZero $2.09 per fax to send up to 25 pages with an optional cover page. Another option is to send and receive faxes from your computer or mobile phone using a dedicated fax number from a service such as FaxDeck. Outbound faxing works almost identically to AvantFax. FaxDeck lets you send and receive up to 300 pages to the U.S. and Canada for $5 a month. Or, for $10 a month, you can send and receive up to 1,000 pages. That’s a penny per page which is less than the cost of most VoIP calls. Many of our recommended providers including Skyetel, ClearlyIP, VoIP.ms, and Vitelity also offer dedicated fax numbers as well as email-to-fax solutions.

Zero-Day Vulnerabilities Compromise All FreePBX Systems



If you’re a user of Asterisk® and FreePBX®, the DEFCON 31 Conference in Las Vegas did not disappoint this year. It exposed not one but three critical, unpatched vulnerabilities in affected FreePBX-based platforms that can compromise your servers in under a minute. I would hasten to add that all of these vulnerabilities were disclosed to Sangoma® months ago and remain unaddressed for months. What this meant was a hacker could easily get administrator privileges on your server with a blank check to make free calls on your nickel or further infect your server with additional hidden components.




 

How Vulnerable Are You? Here’s a quick summary of the bugs documented in the presentation above. If you expose a port on your server to configure SIP phones, you’re compromised. If your users have public IP access to the User Control Panel (UCP), you’re compromised. Any user can delete any asterisk-owned file from your server. Use a Digium® or Sangoma® VoIP phone? You’re compromised. Actually, all you need is the MAC address of one of these phones and its password login and the User-Agent header of any Digium Phone (Digium D60 2_7_0), and you’re compromised if the dphone API RestApp is running on your server. Are you running the API module in FreePBX with public IP address access to your server? You’re compromised because of a bug in the generateDocumentation function. These are classic command injection and authentication bypass issues in FreePBX that can even be triggered from the bad guys’ servers using generated access tokens.


Sangoma, Sangoma. Wherefore Art Thou? You can read all about Sangoma’s Bug Bounty Program here. It was conveniently deleted immediately after this zero-day vulnerability was reported. We’ve reproduced the page from the Wayback Machine. So what happened? According to the good pseudonym researcher, not much. Aside from an initial response indicating that the bugs had been addressed, there was never a follow-up response when the researcher advised that the patches did not work.




 

What Can You Do? Your safest bet is to switch to a security model that does not expose your server or its assets to the public Internet. Incredible PBX is an out-of-the-box platform that provides this security. It’s available for Rocky 8 (not recommended), Debian 11, Ubuntu 22.04 as well as virtualization platforms including VirtualBox, VMware, Proxmox, Windows WSLg, LXC Linux Containers, and Apple’s UTM platform. OpenVPN is also strongly recommended.

At the very minimum, put your server behind a hardware-based firewall with no public Internet exposure until these bugs are properly resolved. You’ve been warned!

Meet the $500 Multi-Purpose Powerhouse: The Acer Aspire 5



We review lots of hardware and numerous operating systems, but none come close to this steal from Amazon for under $500. The Acer Aspire 5 comes in many flavors at many price points. But, if loads of RAM (20GB) and a huge storage capacity (1TB NVMe SSD) top your list of must-haves, nothing we’ve found can touch this deal. The rest of its pedigree is equally impressive: a Ryzen 3 3350U 4-core processor (up to 3.5GHz), backlit keyboard, fingerprint reader for one-touch logins, Amazon Alexa, and Windows 11. As most of you know, our Amazon referral links provide funding to keep the lights on at Nerd Vittles, but none of our recommendations are based upon referral revenue. We eat our own dog food so these are products that we not only test but actually use.

The surprises don’t stop with this hardware discovery. Despite having read a number of articles decrying the lack of Linux support with Acer’s Aspire 5, we found quite the opposite. By setting up a dual-boot configuration, we were able to easily load our absolute favorite desktop Linux distribution, Zorin OS 16. Zorin comes in several flavors: a free offering, a School edition, and a $39 Pro version that can be installed on as many non-business computers as you own. For businesses, you can afford a license for each machine. For schools, there is no charge for the super-charged education edition. We opted for Zorin Pro whose desktop can emulate eight different desktop favorites including Ubuntu, Windows, and Mac. Here are our favorites:


Our project today is to walk you through setting up a dual-boot machine where you can elect to run Windows 11 or Zorin 16 when you startup your machine. Why have two operating systems? The primary reason is you get the best of both worlds. All of the traditional Windows 11 applications will run without a hiccup. And Zorin Pro provides an incredible assortment of apps including the full LibreOffice suite, VirtualBox, music apps including Clementine, video streaming with VLC Media Player, Gnome’s Gmail, Firefox, and a number of free photo editing tools. In short, all apps that will run under Ubuntu will run under Zorin. If you’re a diehard OpenVPN fan like us, it works swimmingly under both operating systems.

Configuring Acer Aspire 5 for Dual-Boot

We won’t bore you with a tutorial on setting up Windows 11 on the Acer Aspire 5. It works much the same way as it does on any other modern computer. Once you get Windows 11 installed, the only change we need to make is to shrink the main Windows partition so that there is some room to install and use Zorin. From the Windows desktop, tap the Windows key and Search for “Create and format hard disk partitions”. Highlight your main Windows drive, usually called “OS (C:)”. Control-tap on the Touchpad in that partition and select “Shrink Volume”. Choose the amount of space to shrink the Windows partition and allocate to Zorin. We chose 250GB, but that’s your call. Reboot your machine for the changes to take effect. When the boot logo appears, press F2 repeatedly to enter the BIOS setup. Click on the Security tab and set a Supervisor Password. No other changes are necessary. Move to the Exit tab and choose Exit and Save Changes to initiate a reboot.

Preparing Zorin 16 Installation Media

Prepare a USB stick after downloading the Zorin 16 ISO of your choice. The easiest method is to download and install balenaEtcher on your desktop machine. It’s available for Windows, Mac, and Linux. Insert your USB stick into your desktop computer and then run the balenaEtcher app. Choose your Zorin ISO after clicking Flash from File. Choose your USB stick from Select Target. Be sure you don’t accidentally choose your desktop’s main drive! Click the Flash button to begin. Once the ISO is transferred, gracefully eject your USB stick from your desktop machine.

Installing Zorin 16 on Acer Aspire 5

Now we’re ready to install Zorin on your Aspire 5. Insert the USB stick and turn on or reboot the computer. The machine will boot Zorin from the USB stick. Choose the LIVE Session option to make sure Zorin will start. Also make sure you can configure WiFi in the Settings -> Network tab. If all goes well, click the Install Zorin link on the desktop to install Zorin onto your empty partition when prompted. Upon reboot, be sure to register Zorin in the UEFI whitelist when prompted.

Enabling VirtualBox in Zorin 16

UEFI machines are temperamental about which non-Windows apps can run. If you wish to enable VirtualBox, here are the steps. First, run the Terminal app and reinstall VirtualBox:

apt remove virtualbox-dkms
apt install virtualbox-dkms

You’ll be prompted to set up a password for your new VirtualBox UEFI key (8 characters). Then reboot and register the new key when prompted. Enter the password when prompted. Now run VirtualBox from the Applications menu, and you should be good to go.

Installing Incredible PBX 2027-U for VirtualBox

Building a Dirt-Cheap Communications Platform with VoIP



There are literally thousands of options when you finally ditch your landline and stagger into the VoIP world. We’re often asked, "What would you recommend if price was the major criteria?" Our response goes something like this. You get what you pay for and our recommended providers continue to be ClearlyIP and Skyetel in no particular order. Having said that, if price is your primary consideration, here’s our Plan B which we use regularly.

First, a word of explanation. This is not the Ma Bell days any longer so you’re not limited by cost to a single provider. It costs little more to have several VoIP providers than to have one since most VoIP services are pay-as-you-go. So, in our least costly category, we actually recommend two providers, BulkVS for VoIP calling and VoIP.ms for VoIP messaging. Faxing also works incredibly well with both of these providers. Just follow our fax tutorial to get started. In terms of deployment, it means you will have one primary phone number for making and receiving calls and a second number for sending and receiving SMS messages. Incoming SMS messages can optionally be delivered to either your primary email account and/or a third phone number such as your cellphone.

Obtaining a phone number to make and receive phone calls through BulkVS will set you back 6¢ a month with a 25¢ initial setup fee. Incoming calls are $0.0023 per minute. Optional 911 support is 49¢/month. Outbound calls to North America are $0.004 per minute. SMS messaging at BulkVS is cost-prohibitive. A phone number (DID) at VoIP.ms to send and receive both calls and messages runs $0.85 per month. Incoming calls run $0.009 per minute. Outbound U.S. calls are a penny a minute while calls to Canada are $0.0052 per minute. SMS messages are $0.0075 per message while MMS messages are 2¢.

We’ll be using Incredible PBX 2027 and PJsip with Asterisk® 20 and FreePBX® 16 to set the trunks up today. We’ll configure the default route for outbound calling to be BulkVS with VoIP.ms as an outage failover. All incoming calls from both DIDs can be directed to a phone, ring group, or IVR of your choice. For SMS messaging, we’ll use the FreePBX GUI to set things up. Scripts also are provided in /root/sms-voip.ms to send messages. We’ll configure the VoIP.ms messaging defaults to also relay incoming messages to both an email address and a cellphone. For additional alternatives, check out our VoIP.ms tutorial.

Getting Started with BulkVS

To get started, click the sign up link on the main BulkVS page. Then fund your account with $25 using PayPal. Or you can sign up for Net 15 billing and pay by check or credit card if you’re not in a rush to get started.

BulkVS offers two ways to set up your BulkVS trunking: IP-based authentication and SIP registration. If you don’t have a firewall which means you’re not using Incredible PBX, the first method is a little safer because nobody can spoof the IP address of your Asterisk® PBX. But it’s not for everyone. For example, if you’re behind a NAT-based firewall or if your server has a dynamic IP address, then IP-based authentication really isn’t an option. Similarly, if you don’t have control of the router that your PBX is sitting behind, then IP-based authentication won’t work since you have to forward both the SIP port (UDP 5060) and the RTP ports (10000-20000) to your PBX. The beauty of SIP registrations is they work from almost anywhere including double-NAT environments. We’ll cover the SIP registration approach below which will work for everyone. See our BulkVS tutorial for additional options.

BulkVS Setup with PJsip Registration

Step 1: Go to Inbound -> DIDs – Purchase and buy one or more DIDs for your PBX.

Step 2: Go to Interconnection -> Host – Add and add your PBX’s public IP address. Leave the port as 5060 for both chan_sip and chan_pjsip setups.

Step 3: Go to Interconnection -> Trunk Group – Add and create a Trunk Group.

Step 4: Go to Interconnection -> Trunk Group – Manage and add the Primary IP Address for your new Trunk Group. Set Delivery Type to 11DIGITS.

Step 5: Go to Interconnection -> SIP Registration and write down the credentials for one of the SIP credentials you wish to use to register your new trunks.

Step 6: Go to Inbound -> DIDs – Manage and select each telephone number. Then set the Trunk Group to the SIPREG Trunk Group you chose in the previous step. Click Update button.

Step 7: Wait 15 minutes for the new IP and Trunk Group settings to propagate to SBC nodes.

FreePBX PJsip Setup with BulkVS Registration

On your Incredible PBX server, navigate to Connectivity -> Trunks after logging into the FreePBX GUI as admin. Choose Add a PJsip trunk. Name the trunk BulkVS and then click on the pjsip Settings tab. Fill out the form as shown below substituting the BulkVS registration account name you chose above. Any of the three SIP registrations offered for your account under Interconnection -> SIP Registration in the BulkVS portal will work as long as you use the matching password.

Next, click on the Advanced tab and enter the following in the Match (Permit) field.

162.249.171.198,76.8.29.198,69.12.88.198,192.9.236.42,52.206.134.245

In the Codecs tab, enable ULAW and ALAW. Then click Submit and reload your dialplan.

With PJsip registrations, you may also need to add the following lines to the end of extensions_custom.conf in /etc/asterisk using your actual DID. Then reload your dialplan: asterisk -rx "dialplan reload"

[from-sip-external]
; BulkVS
exten => 18005551212,3,Goto(from-trunk,${DID},1)

VoIP.ms Messaging Services

One of our favorite VoIP.ms features is the variety of SMS and MMS messaging options they provide AT LOW COST. Virtually all of their DIDs now support messaging. With incoming messages, you have the choice of routing the messages to an email address, another SMS destination, the VoIP.ms Message Portal, an SMS URL callback destination, and now an SMS SIP account. The steps below set up SMS SIP messaging with Incredible PBX 2027. You also can send quick messages in response to incoming calls using your Clearly Anywhere softphone.

Configuring VoIP.ms for SMS SIP Messaging

Prerequisites: DID supports messaging, SMS SIP messaging enabled on the DID

First, use our VoIP.ms signup link to create a VoIP.ms account. Next, create an Asterisk SubAccount using the SIP protocol with User/Password Authentication. In the Security section, enter the public IP address of your PBX, and Save your Settings. Next, acquire a DID in the VoIP.ms portal. Then choose the Manage DIDs option and edit your DID configuration. For Call Routing, select the SIP/IAX option and pick your SubAccount. Choose a DID POP location near your PBX. In the Message Service section, enable SMS SIP Account and pick your SubAccount. Then Apply Changes.

Configuring Incredible PBX for SIP Messaging

Prerequisites: PJsip VoIP.ms Trunk, PJsip Extension for SMS, sms-in and sms-out Contexts

Both PJsip Trunks and PJsip Extensions in FreePBX now support a Messages Context option in the Advanced tab of the setup GUI. Using the sms-in and sms-out contexts documented below, FreePBX now can process incoming and outgoing SMS messages. A typical use case in the Incredible PBX 2027 would be to quickly respond to an incoming call to the Clearly Anywhere app on your smartphone to indicate that you were in the midst of another call and would return the caller’s call. It is anything but a robust SMS messaging application for your smartphone, but it is a welcome addition for many mobile users that have to juggle both cellphone calls and office calls forwarded from a PBX to your smartphone. VoIP.ms has developed an excellent SMS Management Portal that is included in the VoIP.ms Dashboard. It allows you to read, respond, and manage SMS messages sent to your VoIP.ms DIDs.

Once you have completed the necessary setup steps on the VoIP.ms side, there are three steps to activate SMS SIP messaging with Incredible PBX 2027: (1) create and register your VoIP.ms PJsip Trunk, (2) create and configure a PJsip extension to receive incoming calls and SMS messages, (3) add the sms-in and sms-out contexts to extensions_custom.conf dialplan.

(1) Create a PJsip Trunk for VoIP.ms in the FreePBX GUI to process calls and SMS messages:


In the PJsip Settings tab, fill out the General tab. The Username will be your VoIP.ms account number followed by an underscore and then the name of the SubAccount you created above, e.g. 12345_mypbx. The Password will be the password you assigned to your VoIP.ms SubAccount. For SIP Server, enter VoIP.ms POP assigned to your DID, e.g. atlanta1.voip.ms. Accept the remaining defaults in the General tab. Click on the Advanced tab and scroll down to Message Context and enter sms-in. Click Submit and Reload your Dialplan.

(2) Next create a PJsip Extension in the FreePBX portal. This will be used to process calls and send SIP messages. NOTE: Incredible PBX 2027 ships with a number of extensions preconfigured. Only extension 701 is a PJsip extension. Do NOT use the others. If needed, create an additional PJsip extension for messaging. The General tab should look something like this:



Click on the Advanced tab and scroll down to Max Contacts and enter a number that is one more than twice the number of phones that will be connected simultaneously to this extension. For example, if you have 3 smartphones connecting to this extension, enter 7. Scroll down to Message Context and enter sms-out. Click Submit and Reload your Dialplan.

(3) Finally, cut-and-paste the following code into the bottom of extensions_custom.conf in the /etc/asterisk directory:

[sms-out]
exten => _.,1,NoOp(Outbound Message dialplan invoked)
exten => _.,n,NoOp(To ${MESSAGE(to)})
exten => _.,n,NoOp(From ${MESSAGE(from)})
exten => _.,n,NoOp(Body ${MESSAGE(body)})
;
; add your VoIPms info in the next 3 lines
exten => _.,n,Set(VOIPMS_ACCOUNT="123456_subacct")
exten => _.,n,Set(VOIPMS_POP="atlanta.voip.ms")
exten => _.,n,Set(VOIPMS_TRUNK="VoIPms-PJsip") ; actual VoIP.ms trunk in FreePBX
;
exten => _.,n,Set(NUMBER_TO=${CUT(CUT(MESSAGE(to),@,1),:,2)})
exten => _.,n,Set(EXTENSION_FROM=${CUT(CUT(MESSAGE(from),@,1),:,2)})
;
; Now map your sending extensions EXTENSION_FROM to corresponding DIDs NUMBER_FROM
exten => _.,n,Set(CASE_701=6005550101) ; ext 701 msgs originate from 6005550101
exten => _.,n,Set(CASE_702=6005550102) ; ext 702 msgs originate from 6005550102
exten => _.,n,Set(CASE_703=6005550101) ; ext 703 msgs originate from 6005550101
;
exten => _.,n,Set(NUMBER_FROM=${CASE_${EXTENSION_FROM}})
exten => _.,n,Set(ACTUAL_FROM="${NUMBER_FROM}" )
exten => _.,n,Set(ACTUAL_TO=pjsip:${VOIPMS_TRUNK}/sip:${NUMBER_TO}@${VOIPMS_POP})
exten => _.,n,MessageSend(${ACTUAL_TO},${ACTUAL_FROM})
exten => _.,n,NoOp(Send status is ${MESSAGE_SEND_STATUS})
exten => _.,n,Hangup()
;-------------------------------------------------------------------------

[sms-in]
exten => _.,1,NoOp(Inbound SMS dialplan invoked)
exten => _.,n,NoOp(To ${MESSAGE(to)})
exten => _.,n,NoOp(From ${MESSAGE(from)})
exten => _.,n,NoOp(Body ${MESSAGE(body)})
;
; enter your default incoming SMS extension below
; if you want SMS messages delivered to multiple extensions,
; clone additional MessageSend lines below with extension numbers
exten => _.,n,Set(EXTENSION=701)
;
exten => _.,n,Set(ACTUAL_FROM=${MESSAGE(from)})
exten => _.,n,Set(HOST_TO=${CUT(MESSAGE(to),@,2)})
exten => _.,n,Set(NUMBER_TO=${MESSAGE_DATA(X-SMS-To)})
exten => _.,n,MessageSend(pjsip:${EXTENSION}@${HOST_TO},${ACTUAL_FROM})
exten => _.,n,NoOp(Send status is ${MESSAGE_SEND_STATUS})
exten => _.,n,Hangup()
;-------------------------------------------------------------------------

In the pasted [sms-out] context, insert your actual VOIPMS_ACCOUNT, VOIPMS_POP, and VOIPMS_TRUNK name in the lines provided. Then map each extension from which you wish to send SMS messages to a VoIP.ms DID on your PBX in the lines provided. In the pasted [sms-in] context, enter the EXTENSION number which should receive incoming messages from the PJsip trunk in which you designated [sms-in] as the Message Context. There is no magic to the [sms-in] context name. If you have more than one PJsip trunk, simply create additional incoming contexts (such as [sms-in-2]) for each additional trunk and clone the [sms-in] code designating the desired extension to receive incoming messages from each DID. For the [sms-out] context, it can be used as the Message Context for multiple extensions that should be enabled to send outbound SMS messages.

Save the file, and reload the Asterisk dialplan: asterisk -rx "dialplan reload"

Once all the pieces are in place, SMS messages sent to your VoIP.ms DID will be delivered to the FreePBX trunk registered to the SMS SIP destination specified in your VoIP.ms DID setup. And here’s one more tip. If you happen to have a Yealink T46G (not T48G) or a Grandstream GXV phone that is also registered to that extension, the messages will also pop up on your desktop phone with an alert tone. On Grandstream GXV Android phones, we recommend dragging the SMS app to the main screen so that the incoming message count appears beside the SMS icon when new messages are received.

FreePBX Inbound & Outbound Route Configuration

Finally, we need to tell FreePBX how to route calls and messages into and out of your PBX. In the FreePBX GUI under Connectivty -> Inbound Routes, add a new route for BulkVS specifying the 11-digit DID you purchased from BulkVS. Choose a Destination for the incoming calls, save your settings, and reload the dialplan. Repeat this process for your VoIP.ms DID making sure to enable faxing if you’ve completed the fax tutorial.

Next, navigate to Connectivity -> Outbound Routes and modify the default Outbound Route for all outgoing calls. Assign the BulkVS trunk as the first entry in the call sequence and the VoIP.ms trunk as the second entry. In the Dial Patterns tab, you would want match patterns for 1NXXNXXXXXX and NXXNXXXXXX. For the latter entry, be sure to add a Prepend entry of 1. Then save your settings and reload the dialplan.

Interconnecting Incredible PBX Servers with PJsip


Much has been made of the lack of multi-tenant functionality with Asterisk® and FreePBX®. Today we’ll show you how to interconnect as many Asterisk servers as you like and make transparent calls between all of them at zero cost. Setup time is under 5 minutes per server. When you couple PBXs with distributed infrastructure and inexpensive cloud servers costing $25 or less a year and on-premise virtual machine platforms including Proxmox, VMware ESXi, VirtualBox, Windows 11 WSL, and Mac UTM, it makes little sense in terms of reliability and redundancy to put all your eggs in one basket with a MultiTenant telephony solution.

PJsip Interconnection Design

Our basic design goes like this. Create as many decentralized Incredible PBX platforms as you need to cover the various locations of your business. Whether that’s two cities or eighty-nine, the design is the same. Next, use the same extension design at every site. For example, in each location choose 3-digit extensions in the 100 range for management offices and the receptionist, in the 200 range for human resources, in the 300 range for IT services, and so on. Next, number your locations. For nine or fewer cities, use single digits. For up to 89, use two digits beginning with 10. We actually use the last octet of our server’s OpenVPN IP address for the dialing prefix. For our example, we’ll use 1 for the Atlanta office, 2 for Dallas, and 3 for Boston. When someone in Atlanta wishes to call the main human resources number in Dallas, the user would dial 2200. For Boston, they’d dial 3200. And, when someone in Dallas or Boston wishes to reach the main HR number in Atlanta, they’d dial 1200. Assuming the receptionist in each location has extension 100, callers in Dallas would dial 1100 for Atlanta and 3100 for Boston. Hopefully, you get the idea now. Sketch these out on a piece a paper until it all makes sense to you.

You’ll need static IP addresses for each of your Incredible PBX servers. But, if one or more of your servers are sitting behind a corporate firewall, that’s not a deal breaker. Simply set up an OpenVPN network and assign a private OpenVPN IP address to each server. Then use these OpenVPN IP addresses in interconnecting your servers rather than static, public IP addresses. OpenVPN addresses are automatically whitelisted in the Incredible PBX firewall. For other IP addresses, you’ll need to whitelist them using the add-ip utility in the /root folder of each of your PBXs. Be sure to also add the IP addresses of the servers to the ignoreip list in /etc/fail2ban/jail.conf. Note in our design that, for security reasons, PJsip trunks must be created on BOTH the sending and receiving PBXs before interconnected calls between the servers will successfully complete. You wouldn’t want strangers making PJsip calls through your servers. In the alternative, if you only want to enable outbound calls from one PBX to another, you can avoid creating a PJsip trunk on the destination server and instead enable Outbound Authentication on the originating server. In this case, you also will need to enter extension credentials from the destination server in the PJsip Username and Secret fields. But let’s continue on assuming you want calls to flow in both directions.

Using our 3-city example, let’s begin by configuring the Atlanta PBX using the FreePBX GUI. Login to the web interface as admin and navigate to Connectivity -> Trunks. We want to create two PJsip trunks, one to connect to Dallas and another to connect to Boston. Similarly, in Dallas, we’ll create PJsip trunks for Atlanta and Boston. And, in Boston, we’ll create PJsip trunks for Atlanta and Dallas.

Configuring PJsip Trunks For Each Location

On the Atlanta PBX, click the Add Trunk button and choose Add SIP (chan_pjsip) Trunk. For the first PJsip trunk, in the General tab, let’s keep it simple and enter Trunk Name as Dallas. Leave the remaining default settings and click the pjSIP Settings tab. Leave all of the default settings as they are in both the Advanced and Codecs tabs. In the General tab, change the Authentication and Registration settings to None. For the SIP Server IP address, enter the IP address (or OpenVPN address) of the Dallas server. For the SIP Server Port, enter 5061. Finally, change the Context entry to from-internal. That’s all the settings you’ll need. So click Submit and Apply Config when prompted. Repeat the drill for Boston.


Configuring Outbound Routes For Each Location

Next, we need to create two Outbound Routes for calls to Dallas and Boston. Navigate to Connectivity -> Outbound Routes. For each city, click Add Outbound Route. Name the Outbound Route using the city name, e.g. Dallas. Change the Time Zone, if required. For the Trunk Sequence, choose the Trunk with the matching City name from the pull-down menu. Next, click the Dial Patterns tab. Here you’ll need to decide which calls you want to permit between the Headquarters office and Dallas. For the Dallas extensions, you would enter 2 in the Prefix field and NXX in the Match Pattern field. If there are 4-digit numbers on the Dallas PBX that you want to enable for callers from Atlanta, you add another Dial Pattern with the 2 Prefix and NXXX for the Match Pattern. If you want callers from Atlanta to be able to use Outbound Routes on the Dallas PBX to make PSTN calls, you would add another Dial Pattern with the 2 Prefix and NXXNXXXXXX for the Match Pattern. Similar additions could be made for international calls assuming you allow them on your Dallas PBX. Once you’ve added the desired Match Patterns, click Submit and Apply Config when prompted. Repeat these steps to add an Outbound Route for Boston, and you’re finished on the Atlanta PBX.


Repeating the Setup Process in Other Cities

Now simply repeat the steps above on each of your PBXs. For PJsip trunks, you’ll need to create one for every other city in your operation. And, for Outbound Routes, do the same. Once all of your PJsip trunks are activated, you can verify functionality in the Asterisk CLI with this command: pjsip show aors. Once the Status for each city displays as Avail, you can begin making test calls between the servers using a phone connected to each PBX.
