The Most Versatile VoIP Provider: FREE PORTING
JUST RELEASED: Visit the Incredible PBX WikiA New Day: Introducing Incredible PBX 2021 Beta for Debian
Shifting gears is never easy, and sometimes it takes an ill-advised corporate blunder to move the needle. But IBM’s decimation of the CentOS project last week was just the motivation we needed to begin exploring alternatives for the Incredible PBX project. We are delighted to introduce the beta release of Incredible PBX 2021 for Debian 10 for those with a pioneering spirit that would like to participate in development of this promising new platform.
Before we get started, a few cautionary notes. This is not production-ready software. It’s been in development for less than a week by a single individual. As much as we believe in miracles, this probably is not one of them. Having said that, many talented individuals on the VoIP-Info.org Forum have taken this for a spin and offered numerous suggestions. You, too, can follow our progress and participate. With a little luck, we’ll have a production-ready release before the end of 2020. We’ve successfully built a fully-functional version of Incredible PBX 2021 with on-premise hardware using VirtualBox and VMware ESXi. And we’ve deployed virtual machines at Vultr and Digital Ocean without a hiccup.
For those that would like to roll up your sleeves and contribute to this open source project, here’s how to get started. If you’re using on-premise hardware, begin by downloading the netinst ISO image of Debian 10.7 for amd64. Follow our previous tutorials for tips on installation with VirtualBox or VMware ESXi. If you’d prefer to experiment in the cloud for about a penny an hour, open an account at Vultr or Digital Ocean using our referral links that support the Nerd Vittles project. You’ll also get some free credit to try out the service. Then create a new $5/month Debian 10, 64-bit instance in your favorite city.
Once your Debian 10 platform is up and running, login as root using SSH or Putty and issue the following commands:
wget http://incrediblepbx.com/IncrediblePBX2021.sh chmod +x IncrediblePBX2021.sh ./IncrediblePBX2021.sh
At about 5 minutes into the install procedure, you’ll be prompted for your telephone country code. It’s 1 for Canada and the United States. Just before the install completes, you’ll be prompted to save your default IPtables setup. Once the installation completes, reboot and you should be good to go. For tips on next steps, review the Incredible PBX 2020 CentOS 7 tutorial.
After you log back in following a reboot, check the version of Debian 10 in the pbxstatus display. If it’s less than 10.7, issue the following commands to bring your server up to Debian 10.7. Do NOT do this before the base install is finished, or Asterisk may fail to install properly.
apt-get update apt-get upgrade -y
Next Steps with Incredible PBX 2021
Before you can manage your PBX through a web browser, you first will need to set the admin passwords for FreePBX, Apache web apps such as Reminders and AsteriDex, and AvantFax (if you are using Incredible Fax). These all can be set by logging into your server as root and issuing the following commands: admin-pw-change, apache-pw-change, and avantfax-pw-change. The AvantFax password can also be reset with a browser by first logging in as admin with a password of password.
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, if you have turned on two-factor authentication for your Gmail account, 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 password in hand, log into your server as root and run: /root/enable-gmail-smarthost-for-sendmail.
If your Incredible PBX 2021 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 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.
If you want to send and receive faxes with Incredible PBX 2021, run the following script while logged into your server as root: /root/incrediblefax2020-debian10.sh. When prompted, accept all the defaults. Once the HylaFax and AvantFax components are installed, reboot your server. To send faxes, click on the AvantFax tab in the FreePBX GUI and enter your login credentials (default: admin/password). To receive incoming faxes once you have configured a trunk and DID for your PBX, login to the FreePBX GUI as admin. Navigate to Connectivity -> Inbound Routes. For each of your DIDs on which you wish to receive faxes, select the inbound route and click the Fax tab. Review the Default Inbound Route Fax settings for proper setup.
NOTE: If you get a database error when you attempt to access AvantFax from a web browser, log into your server as root and reinstall the AvantFax database: ./avantfax-db-replace.
Audio Issues with Incredible PBX 2021
If you experience one-way or no audio on some calls, 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 Incredible PBX 2021 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 2021 server to an existing OpenVPN network, begin by creating an incrediblepbx2021.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 2021 server. Next, issue the following commands to put the remaining pieces in place:
cp -p /root/openvpn-start /etc/. echo "[Unit] Description=openvpn2021 ConditionPathExists=/etc/openvpn-start After=rclocal.service [Service] Type=forking ExecStart=/etc/openvpn-start /etc/incrediblepbx2021.ovpn TimeoutSec=0 StandardOutput=tty RemainAfterExit=yes PermissionsStartOnly=true SysVStartPriority=99 [Install] WantedBy=multi-user.target" > /etc/systemd/system/openvpn2021.service
Finally, enable the new openvpn2021.service and reboot your server. The OpenVPN IP address should now appear on the LAN line in pbxstatus:
systemctl enable openvpn2021.service reboot
Incredible PBX 2021 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 2021 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.
avantfax-email-change is used to change the destination email address for incoming faxes.
avantfax-pw-change is used to change your admin password for the AvantFax web console.
iaxmodem-restart is used to restart the modems used to send and deliver faxes. The pbxstatus display will tell you whether the IAXmodems are down.
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 2021.
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 2021 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 2021. 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.
sms-skyetel is a script to send SMS messages using a Skyetel trunk.
sms-voip.ms is a script to send SMS messages using a VoIP.ms trunk.
sms-blast, sms-blaster, and sms-dictator are scripts for message blasting. Tutorial here.
switch-to-php5.6 is a script to disable PHP 7.3 and set PHP 5.6 as the default version for your PBX. PHP 5.6 is required to use AvantFax. It is the default configuration for Incredible PBX 2021. The current default PHP version is displayed in the Apache listing of pbxstatus.
switch-to-php7.3 is a script to disable PHP 5.6 and set PHP 7.3 as the default version for your PBX. You cannot use AvantFax when PHP 7.3 is the default.
timezone-setup is a script to set the timezone for your PBX.
update-IncrediblePBX is a script that runs the Automatic Update Utility whenever you login to your server as root. These updates typically resolve bugs and security issues with your PBX. Do NOT remove it.
wolfram is a script to deploy Wolfram Alpha on your PBX. Tutorial here.
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 systemctl restart apache2 /root/sig-fix

Capitalism 101: IBM Castrates CentOS to "Improve" RHEL
If you loved the PC Jr. and New Coke, you’re going to love yesterday’s technology news. Claiming the best of intentions, IBM® cut the 8-year life span of CentOS® 8 to one year after which CentOS will become CentOS Stream, an experimental development platform sandwiched between Fedora® and Red Hat Enterprise Linus®. If you’ve spent the last year or two planning for or deploying CentOS 8, too bad. You can either pay up for RHEL licenses going forward or switch to a new platform. The government-sponsored Scientific Linux project folded into CentOS so that option no longer exists. Oracle Linux® remains an option but, considering Oracle’s track record with MySQL, that might give many organizations pause. For organizations with thousands of CentOS platforms, the remaining alternatives are PAINFUL. Both Debian and Ubuntu would require major software plumbing changes. There’s always a chance that the original CentOS developers will come to the rescue with a new product, but we’re not holding our breath.
So here we are. How does this affect Incredible PBX? As most of you know, we’ve had Incredible PBX 2020 versions for both CentOS 7 and Raspbian 10 for the Raspberry Pi®. There will be no CentOS 8 release of Incredible PBX, but you’ve got four more years of CentOS 7 support unless IBM welches on that commitment as well. Because Raspbian 10 is a derivative of Debian 10, moving forward it makes perfect sense to consolidate onto the Debian 10 platform. And Incredible PBX 2021 will do just that with versions for Debian 10 and Raspbian.
With a little help from Santa, we hope to have a beta release of Incredible PBX 2021 for Debian before the end of this month. Stay tuned. The world will not end.

Meet Acer Spin 713: A Phenomenal Computer for All Seasons
It’s a portable office. It’s a movie theater. It’s a LAMP server. It’s a desktop PC. It’s a tablet computer. It’s a Chrome browser. It’s an Android platform. It’s a Linux server. And it gets almost 8 years of free software and firmware updates. Meet the $629 Acer Chromebook Spin 713. And, if you hurry, it’s $80 off at Best Buy today.
The checklist of superlatives is almost too lengthy to mention: a touchscreen of unrivaled quality, a 12-hour battery, dongle-free ports galore: HDMI, USB-C, USB 3.0, microSD slot, and headphone jack. While Chromium notebooks began as little more than a Chrome browser, that was then. The 2020 iteration includes complete Android integration as well as a feature-complete Debian 10 virtual machine platform supporting Apache, PHP 7, and the latest MariaDB/MySQL. If movies and television are your thing, Netflix and Sling TV transform the Chromebook into a near perfect viewing platform. As they say, seeing is believing. So here’s a snapshot from an iPhone that captures the quality of the 2256×1504-pixel (3:2 QHD) display. Suffice it to say, the display is as good or better than our $3,000 MacBook Pro’s screen.
Did we mention Best Buy’s $629 price. This 2-in-1 is a steal. It’s $200 below today’s Amazon pricing and is $400 below the closest comparable Chromebook models. Some may recall that we reviewed the System76 Lemur Pro Linux notebook in August and raved about its pricing at $1322, more than double the cost of Acer’s Spin 713. Having used both machines, I can honestly say you lose nothing by choosing the Acer device, and you gain access to the entire Android platform including Google Play as well as Linux. And the Spin 713 converts into a touchscreen tablet simply by flipping the screen. The only downside is, if these machines go on sale for Black Friday, you will be hard-pressed to find one to buy.
Deploying a LAMP Server with a Chromebook
If you pick up one of these bad boys, here’s a quick primer on setting up a LAMP server on the Linux virtual machine. Begin by enabling it in the Settings tab. Next, click on the Linux Terminal option in your Applications. At the Linux prompt, set up a new root user password: sudo passwd root. Switch to the root user account: su root. Now enter these commands:
cd ~ apt update apt upgrade apt install apache2 apache2-utils -y systemctl start apache2 systemctl enable apache2 chown www-data:www-data /var/www/html/ -R apt install mariadb-server mariadb-client -y systemctl start mariadb systemctl enable mariadb mysql_secure_installation apt install php7.3 libapache2-mod-php7.3 php7.3-mysql php-common \\ php7.3-cli php7.3-common php7.3-json php7.3-opcache php7.3-readline \\ php7.3-mbstring php7.3-dev -y systemctl restart apache2 echo "<?php phpinfo(); ?>" > /var/www/html/info.php echo "ip a" > /usr/local/bin/ifconfig chmod +x /usr/local/bin/ifconfig ifconfig | grep "inet "
Make note of your Linux machine’s IP address (last command above) and use a browser to access and verify the PHP info for your server: http://Spin-IP-Address/info.php
In the alternative, use this FQDN: http://penguin.linux.test/info.php
In keeping with their tradition of idiotic obsolescence, the PHP developers dropped support for mysqli in PHP 7 which means the mysql_connect function to interact with MySQL databases fails. Here’s how to restore it:
mkdir /usr mkdir /usr/src apt install build-essential git cd /usr/src git clone https://github.com/wardmundy/pecl-database-mysql mysql --recursive cd mysql phpize ./configure make make install cd /etc/php/7.3/apache2 echo "extension=/usr/lib/php/20180731/mysql.so" >> php.ini systemctl restart apache2
The mysql and mysqli sections will now magically reappear in your phpinfo() listing.
Adding Clearly Anywhere Softphone to the Spin 713
As noted, the Spin 713 also is a fully functional Android platform so adding the Clearly Anywhere softphone is easy. Simply download the software from Google Play. Then run the app and enter your extension credentials and FQDN of Incredible PBX 2020 PUBLIC server.
Adding Linphone Softphone to the Spin 713
Adding the Linphone softphone is equally easy. Simply download the software from Google Play. Then run the app and enter your Linphone SIP credentials with the configuration setup documented in our tutorial. Linphone calls to other Linphone users and to Incredible PBX 2020 PUBLIC users or anyone with a SIP URI worldwide are free.
Installing OpenVPN for Android on the Spin 713
There are several ways to install OpenVPN on the Spin 713 platform. You can use the traditional method we’ve documented for Linux installs; however, you will lose the ability to use OpenVPN IP addresses from your desktop and browser. The better method is to install the OpenVPN for Android client from the Play Store. Next, send yourself an email with the .ovpn file you created for the Chromebook. Open the message using Gmail on the Chromebook and save the received file in your Downloads folder. Open the OpenVPN for Android app on your desktop. Choose the + icon to create a new Profile and select the .ovpn file from Downloads. Once installed, edit the Settings. In the IP and DNS tab, disable No Local Binding. Enable Override DNS Settings and specify 8.8.8.8 and 8.8.4.4 for your DNS servers. Enable PULL Settings.In the ROUTING tab, enable Bypass VPN for Local Networks and Block IPv6. Then Start the VPN Client by clicking on your saved Profile.
Installing Zoom for Debian 10 on the Spin 713
No computer platform would be complete without Zoom. Begin by downloading Zoom for Debian here. In the File Manager (Alt-Shift-m), navigate to your Downloads folder and double-click on zoom_amd64.deb to install the application. Once installed, it will appear in your Linux apps container. Right-click (HINT: tap touchpad with two fingers) on Zoom icon to add Zoom to your Shelf.
Installing phpMyAdmin for PHP 7.3 on the Spin 713
No development platform would be complete without phpMyAdmin. We found an excellent tutorial to get everything set up properly with a few minor changes. Your LAMP platform already is in place so skip down to Step 2 in the tutorial. There’s one important correction in the instructions. Step 4, item 1 should be: sudo mkdir /var/www/html/phpmyadmin. And accessing phpMyAdmin once installed should be: http://Spin-IP-address/phpmyadmin.
Mastering Chromebook Shortcuts on the Spin 713
If you learn no other keyboard shortcut, remember this one: Ctrl + Alt + /. That gets you the entire list of keyboard shortcuts on the Chromebook. These keyboard shortcuts are a bit like memorizing multiplication tables. The sooner you learn them, the happier you will be using your Chromebook. If you’re an avid Linux user, be advised that the Linux virtual machine and the Chromebook desktop share the same clipboard so you can easily copy-and-paste between the two environments. On the desktop, Ctrl-c copies to the clipboard, and Ctrl-v pastes data from the clipboard. In the Linux virtual machine, Ctrl-Shift-C copies to the clipboard, and Ctrl-Shift-V pastes data from the clipboard. Learn a few new shortcuts each time you use your Chromebook. You’ll be amazed how quickly your productivity improves.
Where To Go From Here?
While you’re getting your feet wet, here are some must-have’s for your Spin 713. For openers, feast your eyes on the 4K Nature Videos on YouTube. Prepare to be blown away.
Next, you’ll want a free Office Suite for your Chromebook. Our favorite is WPS Office which provides Microsoft-compatible versions of Word, Excel, Powerpoint and a PDF Viewer/Editor.
For video editing, nothing comes close to PowerDirector. Also check out YouTube Studio.
For photo editing, Adobe Lightroom is the hands-down winner. Google Photos and Snapseed (our personal favorite) are also worth a careful look. Both are free compliments of Google.
For Nerds, check out the Crostini Wiki on Reddit. And master the Crosh terminal commands.

The Most Important Asterisk Component: It’s the Backups!
You might think Backups are critical in the event of a catastrophic hardware failure. And you’d be right. But there are other equally important reasons to maintain current backups. If you decide to migrate to a new server platform, a current backup makes it a painless exercise. If you need to recover from a FreePBX® module upgrade that hosed your server, a current backup is critical. If you want to migrate to a newer release of Asterisk® or FreePBX, a backup is all that stands in the way of a potential nightmare or days of drudgery.
Depending upon your server platform, there are a number of backup methodologies. The most obvious one is Incredible Backup 16 which was used to build your initial Incredible PBX® 2020 platform. Next is Incredible Backup 2020 which is available on the new Incredible PBX Wiki. A third backup option is the FreePBX Backup & Restore Module which is included in all Incredible PBX 2020 builds. On cloud-based server platforms from CrownCloud, Vultr, and Digital Ocean, there’s a backup or snapshot option built into the platform. On Vultr and Digital Ocean servers, backups are an optional feature for an additional 20% monthly charge. On CrownCloud servers, a free snapshot is included in your $25 annual fee. Other cloud platforms have different backup options. For on-premise virtual machine platforms such as VirtualBox and VMware, there are snapshot and backup options built into the platform. And, of course, there are disk imaging backup options such as Clonezilla, Mondo Rescue and dozens of other Linux backup solutions. Today we want to walk you through which backup alternatives work best depending on platform and the level of protection desired.
Incredible PBX 2020 Backup & Restore
As noted, Incredible PBX 2020 Backup & Restore is the newest release of backup and restore utilities for Incredible PBX 2020 platforms. It’s available for download from the Incredible PBX Wiki. To make a backup, run: /root/incrediblebackup2020. You would typically use it to recover from a catastrophic hardware failure or to migrate your PBX to a new, compatible platform such as moving from CentOS 7 on-premise hardware to a cloud-based CentOS 7 platform or migrating a VirtualBox installation to dedicated hardware. It backs up the entire web directory tree as well as all MySQL databases in addition to Asterisk files that you may have customized. It is well suited for restoration of an Incredible PBX 2020 server setup onto the same operating system platform from which the backup was made. In other words, you wouldn’t use it to restore an Incredible PBX 2020 server from a CentOS 7 platform to a Raspberry Pi platform or vice versa. Before restoring an Incredible PBX 2020 backup, you must first build the new server with the same operating system, Asterisk, and FreePBX versions as the backup image, i.e. a new Incredible PBX 2020 installation for CentOS 7 or Raspbian 10. Next, install the Incredible PBX 2020 Backup & Restore components. Finally, copy your Incredible Backup 2020 image to the /backup folder of the new server and then run: /root/incrediblerestore2020.
FreePBX Backup & Restore Module
The FreePBX Backup & Restore Module is included in all Incredible PBX 2020 servers. It is accessed by logging into the FreePBX GUI as admin and navigating to Admin -> Backup & Restore after creating a Storage Location with Settings -> Filestore. For example, to create a backup directory in /var/spool/asterisk, the Local filestore entries would look like this:
The typical use case would be to recover from a module update scenario that went awry, to migrate from one FreePBX 15 platform to a new one with an incompatible operating system, e.g. to move from a Raspberry Pi to a CentOS 7-based server. It is also useful for upgrading from an Incredible PBX 13-13 platform to Incredible PBX 2020 but, for this to work, you must first remove the OSS Endpoint Manager module on the Incredible PBX 13-13 server.
To restore a FreePBX backup onto a new platform, repeat the steps above to set up the FileStore on the new server. Then copy the backup image from /var/spool/asterisk/backup to your desktop. Next, run the Restore option on the new platform and upload the backup image from your desktop.
Cloud Server Backups & Snapshots
Depending upon your cloud hosting provider, the procedure to create backups and snapshots may differ. The important point to stress is that these backups and snapshots are extremely easy to create but typically are housed in the same network operations center and often on the same server as your PBX. The risks in using these backup and snapshot options as your sole recovery mechanism from a catastrophic failure should be obvious. When combined with an off-site Incredible Backup 2020 image, you’re protected from a NOC catastrophic failure.
VirtualBox Backups & Snapshots
On the VirtualBox platform, you’ll find the Snapshot utility under Machine -> Tools. The other option is a full backup which is accomplished in one of two ways. For an external backup, choose File -> Export. For a backup in place, choose Machine -> Clone. The usual warnings about storing your backup images off-site apply.
VMware ESXi Backups & Snapshots
On the VMware ESXi platform, you’ll find the Snapshot utility under Actions -> Snapshots. To make an external backup, go to Actions -> Export. The usual warnings about storing your backup images off-site apply.
Installing Mondo Rescue for CentOS 7
The Mondo Rescue install for CentOS 7 is dependent upon a repository that is difficult to ascertain to put it charitably. Here is the correct installation procedure for CentOS 7:
cd /etc.yum.repos.d wget ftp://ftp.mondorescue.org/centos/7/x86_64/mondorescue.repo yum install mondo
For the backup and restore process using Mondo Rescue, follow this TecMint tutorial once you complete the install above.
Cloning a Raspberry Pi microSD Card
Our Incredible PBX 2020 for Raspberry Pi tutorial documents the easiest method for backing up your Raspberry Pi. We are repeating it here for completeness.
rpi-clone is a utility that makes it easy to make a bootable image of the microSD card used to start your Raspberry Pi. You’ll need a USB-to-microSD adapter to begin. Insert a backup microSD card large enough to hold all of the data on the primary microSD card (df -h). Insert the USB stick with the card. Identify the backup microSD card, usually sda (fdisk -l). Format the backup microSD card:
mkfs.vfat /dev/sda1 && mkfs.ext4 /dev/sda2. Then issue the following command to clone the primary microSD card: rpi-clone -f sda. Tutorial here.Originally published: Monday, November 23, 2020

Groundwire for Android & iOS: The Best $10 You’ll Ever Spend
Now we’re getting down to the tough choices in VoIP softphones. You certainly need the Linphone app to make free SIP URI calls worldwide from your mobile phone. But you also need a softphone that connects to Incredible PBX® so that you never miss a traditional call to your home or office PBX. If you want tight integration with Asterisk® and FreePBX®, Clearly Anywhere is the hands-down winner, and you’ve still got until October 31 to take advantage of the $9.99 per year introductory offer. But some folks just bristle at the thought of annual fees for software licenses. If you fall into that category but still want the incoming call reliability offered by Clearly Anywhere, then the one-time $9.99 payment for Acrobits Groundwire on either the Android or iOS platform is your baby.1 Here’s the setup process.
Configuring Incredible PBX 2020 PUBLIC for Acrobits
Before you deploy Acrobits Groundwire on your smartphones, you first must set things up on the PBX side. Here’s how the process works. First, you will need to deploy the PUBLIC version of Incredible PBX 2020 on the Internet. It requires assignment of a fully-qualified domain name (FQDN) for server access. We’ll also need to reconfigure the IPtables firewall and Fail2Ban to support Acrobits Groundwire.
Begin by choosing a cloud provider to host your public server. Here are some of our favorites starting at only a couple bucks a month with an annual subscription. CrownCloud is highly recommended. You’ll need a KVM CentOS 7 platform with at least 1GB of RAM and 10GB of storage. Once your server is operational, log in as root and follow our Incredible PBX 2020 tutorial to begin. When the install finishes, reboot your server and log back in to get the latest updates with the Automatic Update Utility.
Now you’re ready to convert your PBX into a PUBLIC-facing server. You’ll need a fully-qualified domain name for the server. If you don’t have your own domain, you can always obtain a free FQDN from a service such as NoIP.com. With your FQDN in hand, switch over to the Incredible PBX 2020 PUBLIC tutorial to complete the setup. It only takes a few minutes.
Next, we need to whitelist the Acrobits server IP addresses in the IPtables firewall. Begin by editing iptables-custom in the /usr/local/sbin folder. Just above the "# End of Trusted Provider Section" marker, add the following block of code. Then save the file and restart IPtables with the following command: iptables-restart
/usr/sbin/iptables -A INPUT -s 159.65.167.207 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 159.65.186.176 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 159.65.251.173 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 159.65.252.186 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 159.65.253.49 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 159.65.252.186 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 159.65.253.49 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 159.89.179.103 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 162.243.226.164 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 165.227.65.164 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 165.227.115.186 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 165.227.182.9 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 165.227.184.188 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 165.227.190.186 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 165.227.210.221 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 165.227.223.68 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 167.99.48.91 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 167.99.119.203 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -A INPUT -s 167.99.119.244 -p udp -m udp --dport 5060:5069 -j ACCEPT /usr/sbin/iptables -I INPUT -s 165.227.103.7 -p tcp -m tcp --dport 443 -j ACCEPT /usr/sbin/iptables -I INPUT -p tcp -m tcp --dport 7343 -j ACCEPT /usr/sbin/iptables -I INPUT -p tcp -m tcp --dport 4998 -j ACCEPT /usr/sbin/iptables -I INPUT -p tcp -m tcp --dport 24998 -j ACCEPT /usr/sbin/iptables -I INPUT -p udp -m udp --dport 4998 -j ACCEPT
Finally, we need to whitelist the Acrobits server IP addresses in Fail2Ban to be sure your server doesn’t block any of the Acrobits servers attempting to contact your PBX. Ask us how we know.2 Edit /etc/fail2ban/jail.conf and scroll down to line 34 which begins with ignoreip. Add a space at the end of the existing line and then add the following string of IP addresses without a line break. Save the file and restart Fail2Ban: service fail2ban restart
159.65.167.207 159.65.186.176 159.65.251.173 159.65.252.186 159.65.253.49 159.89.179.103 162.243.226.164 165.227.65.164 165.227.115.186 165.227.182.9 165.227.184.188 165.227.190.186 165.227.210.221 165.227.223.68 167.99.48.91 167.99.119.203 167.99.119.244
Configuring FreePBX for Acrobits Groundwire Access
For every Acrobits Groundwire user, you’ll need to have a PJsip extension to which to register their softphone(s). Keep in mind that multiple softphones of a single user or multiple users can register to the same extension. The first phone to answer an incoming call gets connected to the calling party. Using a web browser, access the FreePBX GUI using your admin credentials. Navigate to Applications -> Extensions -> Add PJsip Extension. Choose a Name and Number for the Extension. Click on the Advanced tab, increase the Max Contacts entry by two for each Acrobits Groundwire softphone that will be connecting to this PJsip extension. Save your PJsip extension setup by clicking Submit. Then Reload the Dialplan.
Acrobits Groundwire Setup on Smartphones
The setup process on the smartphone side is simple. Begin by purchasing the Acrobits Groundwire app from either the App Store or Google Play for your device. Once the client softphone is installed, run the app. You will be prompted for the Username (extension), Password, and Domain:Port of your PBX. If your server is sitting behind a router and you’ve elected to use OpenVPN for your connection, then you’ll need to add the actual Public IP address of your server as the Proxy in Advanced Settings. Don’t forget the :5061 suffix if you’re using a PJsip extension on your PBX.
Once connected, click on the Settings icon in Acrobits Groundwire. Verify that Push Notifications are enabled for Incoming Calls. In setting up your connection to a PJsip extension on your PUBLIC server, don’t forget to tack :5061 onto the server’s FQDN. In the Preferences tab, set a Ring Tone for incoming calls and decide whether to record calls. The Network preference by default will choose WiFi and then Cellular with automatic roll-over when needed. If you want 911 calls routed through your cell carrier instead of through your PBX, choose Number Rewriting. Then click +. For Conditions, choose Equals 911. For Actions, choose Override Dial Action and select gsmCall. Click Done.
We hope you enjoy using the Acrobits Groundwire softphone with Incredible PBX 2020.

- As with Vitelity, Acrobits is an Inteliquent company which provides financial support for Nerd Vittles and our Incredible PBX open source project. [↩]
- TRUE STORY: We couldn’t get Groundwire to answer incoming calls and finally opened a ticket withe Acrobits. Within 15 minutes, we got a response from Gabriel Baker, who requested a log which was easily generated from the app itself. About 15 minutes after we sent Gabriel the log, he responded noting that our server was blocking the Acrobits IP address which he provided. Issuing the
iptables -nLcommand on our end quickly revealed that Fail2Ban had blacklisted the address. Whitelisting the Acrobits IP addresses in Fail2Ban instantly solved the problem. One would have to conclude that Acrobits has some of the best tech support in the industry based upon our first-hand experience. [↩]
Linphone Rocks: Free SIP Calling to Anybody, Anywhere
We’re rounding out our softphone series today with the perfect complement to Clearly Anywhere for Asterisk® and FreePBX®. Let’s face it. SIP URI dialing from extensions is not Asterisk’s strong suit which is disappointing since SIP URI calling is free. If you’ve been following Incredible PBX® 2020 developments this year, you already know that we’ve pushed everyone to move their VoIP servers to the cloud. You not only get a more flexible PUBLIC platform that lets you go virtually anywhere while preserving home base connectivity for a few bucks a month. A public Asterisk server also lets anyone in the world call your PBX via a SIP URI, and the calls are free from any SIP phone. HINT: Linphone softphones are free!
Today we want to take a fresh look at one of our favorites, Linphone. We call it the perfect complement to Clearly Anywhere because it installs on almost every platform and provides SIP URI communications without any dependence upon a PBX at all. And, just like Clearly Anywhere, multiple devices can connect to the same Linphone account to make and receive calls. Linphone offers free SIP clients for Windows, Mac, Linux, iOS, Android, and many browsers. There’s even GPL source code if that’s your thing. Here are the download links:
- Windows
- Mac
- Linux
- iOS via App Store
- Android via Google Play
- Web Browser (Chrome, Edge, Firefox, Safari)
- GPL v3 Source Code
To get started, sign up for a free Linphone account. Now simply download the app of your choice from the links above and run it. Then choose the Assistant option and plug in your username and password. Be sure to Allow Push Notifications so that your phone will ring whenever you get an incoming call. Now all you need is a cellular data plan or a wired or wireless network connection. Anyone can reach you at yourname@sip.linphone.org. When friends sign up, their calls also will be free. You can talk as often and as long as you like.
Should you ever lose or forget your password. here’s a link that will let you reset it.
The Linphone feature set is downright impressive. Here’s what you and your friends will be using at zero cost:
CONFIGURATION TIPS: Missing audio or one-way audio is a common problem on SIP calls especially if your phone is sitting behind a NAT-based router. For best results, configure your account in the Linphone app to use UDP for the Transport, Disable the Outbound Proxy, configure stun.linphone.org as the Stun Server, and enable ICE. In Network settings, turn off IPv6 and Media Encryption. In Audio Settings, enable Opus, G.722, PCMU, and PCMA only. In Video Settings, enable both VP8 and H.264. Then close the app and reopen it.
Once you have your Linphone credentials, another option in addition to using one of the SIP clients above is to acquire a stand-alone SIP telephone which can easily be connected to your Linphone SIP account. While there are literally hundreds of SIP telephones from which to choose, here’s a $40 offering from Grandstream that we like. It’s available from Amazon.1 Also consider Incredible PBX phones which take SIP communications to a whole new level.
Unlike other proprietary communications apps, the beauty of using Linphone with its native SIP URI support is you can call any SIP phone in the world for free whether the recipient uses Linphone or not. For example, to annoy your friends and spammers, you can transfer their calls to Lenny: 2233435945@sip2sip.info. And here are some other SIP URI calls you might want to try. Store any or all of them in your Linphone Phonebook.
Your Linphone Friend - friend-name@sip.linphone.org Yahoo News Headlines - news@demo.nerdvittles.com Yahoo News Headlines - 951@demo.nerdvittles.com Weather by Zip Code - weather@demo.nerdvittles.com Weather by Zip Code - 947@demo.nerdvittles.com Directory Assistance - information@demo.nerdvittles.com Directory Assistance - 411@demo.nerdvittles.com Call Any TollFree # - **1800XXXXXXX@tollfree.future-nine.com
There are now more than 2,000 VoIP networks worldwide that support SIP URI access. Any person or organization with an account on any of these networks can be reached at no cost via SIP URI or via several hundred PSTN numbers. Using a SIP URI dialing prefix, you can call any referenced network@sipbroker.com. For example, *656news@sipbroker.com would reach the Nerd Vittles News Headlines from Yahoo. Or, from a PSTN phone, choose a local access number from the SipBroker worldwide directory, e.g. 702-789-0530 and then dial *656951 at the prompt for Yahoo News from Nerd Vittles. Call enabled PBX extensions the same way.
If you want to associate a phone number with your Linphone SIP URI, you can do it in a couple of ways. First, using a smartphone, you can link your cell number to Linphone within the Linphone app itself. If you have a free DID from IPComms, you can point it to your Linphone SIP URI. If you have a $1/month CallCentric DID, it can also be pointed to your Linphone SIP URI.
There’s one more nice surprise. Linphone accounts work much like the old key telephones and Google Voice setup that we all knew and loved. What that means is you can register the same Linphone account on multiple phones in different places.
Calling Linphone Users from Incredible PBX
Since Linphone doesn’t technically assign phone numbers to users’ accounts, you still need a way for PBX extensions to contact Linphone users. The easiest way is to create a Custom Extension for every Linphone user account you need to reach. In the FreePBX GUI, navigate to Applications -> Extensions -> Add Extension -> Custom Extension. Assign an Extension Number and Name to the custom extension. Then click on the Advanced tab. In the Dial field, enter the SIP URI for the Linphone user, e.g. SIP/username@sip.linphone.org. Click Submit and then Reload the Dialplan.

Oldie But Goodie: VoIP.ms, The Most Versatile VoIP Provider
We all are fortunate to have an extraordinary selection of options when it comes to VoIP Providers. For redundancy and reliability, nobody quite matches Skyetel. For FreePBX® and SIP phone integration, ClearlyIP is the hands-down winner. And, if you’re searching for the Most Versatile VoIP Provider, look no further than VoIP.ms, now with a $10 signup credit with your first deposit to kick the tires. We are thrilled that all three of these providers are Platinum Sponsors of Nerd Vittles and our open source projects. Here’s our VoIP.ms signup link.
As we have often stressed, the beauty of VoIP is not having to put all your eggs in one basket when it comes to communications. Most of the offerings we write about are free when not in use. So, unlike in the MaBell days, you lose nothing by signing up with multiple providers and enjoying the best of all worlds. Today we want to highlight what makes VoIP.ms extra special.
VoIP.ms Points of Presence
When it comes to Points of Presence (POPs), VoIP.ms covers all the bases. This matters because the closer your VoIP provider is to the physical location of your PBX, the better your calls will be. In the case of VoIP.ms, your choice of POPs is impressive. In the United States, there are multiple POPs in Atlanta, Chicago, Dallas, Denver, Houston, Los Angeles, New York, San Jose, Seattle, Tampa, and Washington, D.C. In Canada, you can choose between multiple POPs in Montreal, Toronto, and Vancouver. For our international friends, there are POPs in Amsterdam, London, Paris, and Sydney.
VoIP.ms DID Options
In addition to free number porting, VoIP.ms has an impressive array of DIDs from which to choose. They offer DIDs in virtually every state, province, and country in the world as well as toll-free and fax numbers in many locations with per minute and unlimited calling options.
Obtaining VoIP.ms SIP URIs
There are now more than 2,000 VoIP networks that support SIP URI access. Using a SIP URI dialing prefix, you can call any of the referenced networks @sipbbroker.com. The beauty of SIP URI calling is the calls typically are free worldwide regardless of duration. There are a number of ways to obtain a SIP URI for your PBX. Perhaps the easiest is to set up the PUBLIC Incredible PBX cloud platform that we previously introduced. Then you can create as many SIP URIs as you like, and they can be used to perform any task that’s available with Asterisk®. If you’re not quite ready to make that leap, virtual SIP URIs are available from VoIP.ms for 25¢ a month. SIP URIs are treated just like DIDs with incoming calls billed at ⅒¢ per minute.
VoIP.ms Incoming Call Routing
For call routing, the options are equally impressive. In fact, you may decide you don’t need a PBX at all. VoIP.ms supports SIP and IAX2 trunk registrations using credentials or IP address, a customizable IVR, a call queue, conferencing, call forwarding, SIP URI forwarding, call hunting, ring groups, callback, DISA, custom music on hold, voicemail transcription, and impressive call failover options for each of the following conditions: busy, unreachable, and unanswered calls. You can also perform CNAM lookups on incoming calls as well as setting the ring time, customizing each DID’s voicemail setup, and choosing whether to record calls.
VoIP.ms Outbound Call Pricing
No article would be complete without some mention of pricing. VoIP.ms is not the cheapest provider on the planet. But, as the old saying goes, you get what you pay for. Calls to toll-free numbers are free. While that may seem obvious, it is the exception rather than the rule in the VoIP world. Calls to US-48 destinations are a penny a minute and are billed in six second increments. Calls to most Canadian destinations are about a half-cent per minute. Calls to Mexico are just over a penny a minute billed in one minute increments. International calls vary based upon destination and latest published rates. International calls are blocked unless you enable them, and you can choose the countries you wish to enable as well as a dollar limit.
VoIP.ms Messaging Services
One of our favorite VoIP.ms features is the variety of SMS and MMS messaging options they provide. Virtually all of their DIDs now support messaging. With incoming messages, you have the choice of routing the message to an email address, another SMS destination, the VoIP.ms Message Portal, an SMS URL callback destination, and now an SMS SIP account. Our tutorial below sets up SMS SIP messaging with Incredible PBX® 2020 or 2021. You then can send quick messages in response to incoming calls on your Clearly Anywhere softphone.
Configuring VoIP.ms for SMS SIP Messaging
Prerequisites: DID supports messaging, SMS SIP messaging enabled on the DID
First, 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 near your PBX location. 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 2020 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: (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 FreePBX 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 ships with a number of chan_sip extensions preconfigured. Do NOT use these. You need to create a PJsip extension. 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.
