Call By Name for Asterisk with IBM Voice Recognition Returns

Monday, July 25, 2022

It’s been several years since we introduced our Call By Name script for Asterisk® using IBM’s Voice Recognition software. During that time, IBM has shifted gears on their pricing plans and their API methodology several times. So today we want to provide a new soup-to-nuts tutorial for those using Incredible PBX on the Raspberry Pi and Incredible PBX 2021 on both the Debian 10 and Ubuntu 20.04 platforms. If you have previously used IBM voice recognition (STT), be aware that IBM has made significant changes in their service credentials so you’ll need to generate new ones for your account to use these new scripts.

HOW THIS WORKS. On the Incredible PBX platform, you will dial 411 from any extension on your PBX. The system will prompt you for the name of the person or organization to call. Simply say the name and press #. The Call by Name script then will convert your spoken name into text using IBM STT and search the AsteriDex database for a match. If it finds an entry, it will retrieve the phone number and place the call using your default outbound routes.

GETTING STARTED. You first will need to set up an IBM account, choose your Pricing Plan, and generate your Speech-to-Text credentials. Under IBM’s current LITE Plan, you get 500 free minutes of voice recognition a month with no rounding up of actual recording times. The only gotcha with the free tier is that, once you’ve used up your 500 minutes for the month, you’re done until the next month rolls around. If you only use this for Call By Name, you would have to make thousands of queries before that became a problem. So begin by following our existing tutorial to set up your account and choose your pricing plan. Please note that credentials for Speech-to-Text and Text-to-Speech are different. For today, you want STT credentials. Once you’ve navigated to Speech-to-Text LITE, click on Service Credentials in the task bar and then click the blue New Credential button. Accept the defaults and IBM will generate the new credentials for you. Click on the Down Arrow beside your new credentials to display your API key and the URL for future queries. Copy both entries to a safe place and log out of the IBM site.

INSTALLING THE CALL BY NAME SOFTWARE. On most Incredible PBX platforms, a version of the Call by Name software already is in place. But it won’t work with IBM’s new API. Here’s how to bring it up to current specs. Log into your server as root and issue these commands:

cd /var/lib/asterisk/agi-bin
wget http://incrediblepbx.com/callbyname2021.tar.gz
tar zxvf callbyname2021.tar.gz
rm -rf callbyname2021.tar.gz
cd /etc/asterisk
sed -i '\:// BEGIN Call by Name:,\:// END Call by Name:d' extensions_custom.conf
cd /var/lib/asterisk/agi-bin
sed -i '/\[from-internal-custom\]/r ibm-411.txt' /etc/asterisk/extensions_custom.conf
asterisk -rx "dialplan reload"
nano -w getnumber.sh

When the editor opens, scroll down to the following section of the code:

API_USERNAME="apikey"
API_KEY="XXXXXXXXXXXX"
API_URL="https://api.somewhere.stt.watson.cloud.ibm.com/instances/1-2-3-4-5"

Leave the API_USERNAME the way it is. Replace the API_KEY entry with your actual API key (between the quotes). Replace the API_URL entry (between the quotes) with the URL you copied down in the previous section. Now save the file: Ctrl-X, then Y, then ENTER.

TAKING CALL BY NAME FOR A TEST DRIVE. To test things out, pick up a phone connected to your PBX and dial 411. When prompted for the name, say "United Airlines" and press #. You will be connected to United Airlines reservations desk assuming you have a default outbound route for 10-digit numbers.

Deploying Incredible PBX with Microsoft Windows 11

Monday, July 11, 2022

Miracles happen every so often, but we never expected our Linux-based Incredible PBX platform to be running natively on the Microsoft Windows 11 desktop. Some have asked why you’d even want to do this when VirtualBox is available for Windows, and Incredible PBX VirtualBox images are available for Debian 10 and Rocky 8. The short answer is we got kernel crashes on our cheapo Windows 11 hardware. The longer answer is the VirtualBox days are numbered as it won’t run on any of the new ARM-based platforms including Apple’s new Macs. That sent us searching for an alternative. We finally solved kernel crashes in VirtualBox by adding a second CPU core and maxing out the display graphics to 128MB in each VM.

Lo and behold, Microsoft was offering their Windows Subsystem for Linux GUI (WSLg) on GitHub. But, before we could explore the Ubuntu offering, we discovered that they also supported many other distros including Debian. Who’da thunk you could even run LibreOffice from your Windows desktop? So we set out to build not one but two WSLg VMs, one for Ubuntu to run a free office suite and a second for Debian to run Incredible PBX. The icing on the cake is the length to which Microsoft has gone to integrate WSLg into Windows 11. You can read all about it here.

Today, our focus is on showing you how to deploy Incredible PBX on a tiny, $207 Windows 11 powerhouse. If you’re interested in running the LibreOffice suite with Ubuntu, just follow the instructions documented in the GitHub posting. To get started, you’ll need Windows 11 (build 22000.*) or Windows 11 Insider Preview (builds 21362+). To begin, from the Windows 11 Start Menu, search for powershell and then right click on app and choose Run As Administrator.

Here are some wsl commands you’ll want to keep handy:

List Available Linux Offerings  : wsl --list --online
Show Installed Linux Platforms  : wsl -l -v
Install a Linux Virtual Machine : wsl --install -d {distro}
Startup a Linux Virtual Machine : wsl -d {distro}
Shutdown Running Virtual Machine: wsl --terminate {distro}
Remove any Linux Virtual Machine: wsl --unregister {distro}
Backup any Linux Virtual Machine: wsl --export {distro} {filename.tar}
Restore a Linux Virtual Machine : wsl --import {distro} {filename.tar}

Let’s begin by installing a Debian Virtual Machine: wsl --install -d Debian. You’ll be prompted to create a user account and password, e.g. nerd and password. If you’re not prompted to create a user account, reboot your Windows machine and reopen the Debian app which will straighten things out. Once the Debian CLI window appears, enter the following commands to set up the root user account and begin your Incredible PBX install:

sudo passwd root
su root
# enter password you created for root
cd ~
apt install wget -y
wget http://incrediblepbx.com/IncrediblePBX2021-win11.sh
chmod +x IncrediblePBX2021-win11.sh
./IncrediblePBX2021-win11.sh

Stick around long enough to answer a couple of initial prompts, and then go have a very long cup of coffee. The install typically takes 30-45 minutes depending upon your computer’s horsepower. While you’re waiting, notice that the Windows Start Menu now includes a new Debian app which you will use to launch the Incredible PBX virtual machine down the road.

When the install finishes, run the following commands from the Debian CLI:

cd ~
./update-IncrediblePBX
service sendmail start
pbxstatus

Keep in mind that Incredible PBX will be running in a Debian virtual machine under Windows 11. So it’s important to know how to start things up and shut things down. As with any operating system, you don’t want to simply pull the plug and risk damaging both the file system and the MySQL databases.

To start the Debian virtual machine, you can do it in either of two ways. From the Windows Start Menu, double-click on the Debian app. Or from the PowerShell running as Administrator, type: wsl -d Debian. You can verify it’s running like this: wsl -l -v

Once the Debian CLI appears, issue the following commands to activate all of the Linux components upon which Incredible PBX depends:

su root
# enter root password
cd ~
./startup
pbxstatus

The LAN IP address is only accessible from your Windows machine. To run the Automatic Update Utility, you’ll need to SSH into this LAN address from the PowerShell running as Administrator where 172.29.80.223 is the LAN address shown in pbxstatus:

ssh root@172.29.80.223

To shutdown the Debian virtual machine, first open the Debian app and switch to the root user. Issue the halt command. This gracefully shuts down Asterisk, MySQL, and Apache. When the script completes, return to the PowerShell and issue this command to halt the virtual machine: wsl --terminate Debian

Deploying OpenVPN with Incredible PBX. We strongly recommend deploying an OpenVPN client as part of your WSLg install and also on the Windows 11 desktop. It will simplify access to the server both from within Windows and also from any external source without having to wrestle with your firewall settings. This Incredible PBX Wiki article will walk you through creation of an OpenVPN Server platform, and this Incredible PBX Wiki article will walk you through the OpenVPN Client setup process. Simply name your Debian .ovpn config file incrediblepbx.ovpn and save it in the /etc directory for automatic startup.

CAUTION: Be sure to create and use a separate .ovpn configuration file for your Windows desktop including these additional settings documented in the Wiki:

pull-filter ignore redirect-gateway
route-nopull
route 10.8.0.0 255.255.255.0

$300 Chromebook Faceoff: ARM vs. x86? Which Is Better?

Monday, June 27, 2022 / 9 Comments on $300 Chromebook Faceoff: ARM vs. x86? Which Is Better?

We’ve written about the Chromebook before, but today presents an interesting dilemma. Should you choose an ARM-based Chromebook for a bit better performance or an x86-based Chromebook for application flexibility? This becomes even more interesting when one recalls that Apple is poised to dump Intel processors and move exclusively to the ARM platform for all of its next generation machines. The short answer is it depends upon your use case. Cell phones and tablets traditionally have relied upon ARM processors while desktop computers are almost exclusively based upon either Intel or AMD processors. The Chromebooks fall somewhere in the middle because they can perform traditional web browsing and also run dedicated applications traditionally reserved for desktop computing platforms. So we decided to put two of the least expensive Chromebooks to the test. We managed to grab both the ARM64-based Chromebook (pictured above) and the AMD-based Chromebook (pictured below) for equivalent discounted prices of about $300. The HP Chromebook included a rechargeable pen, detachable keyboard and stand, 11″ touchscreen display, and power adapter while the Acer Chromebook included a mouse, backlit keyboard, convertible 14″ touchscreen display, case, and power adapter. Both weigh about 4 pounds with 8GB RAM and 64GB disk.

We decided to test these Chromebooks by determining how well each could perform as a sales demonstration unit for those in the VoIP business. Suffice it to say, there’s nothing quite like a LIVE showing for a potential customer demonstrating how their future Unified Communications platform would work. And the fact that you can pull this is off with what looks very much like a computer tablet is icing on the cake. Both Chromebooks passed the test with ease although we massaged the Incredible PBX installer a bit to accommodate the ARM64 platform. If you decide to try this out for yourself, we’ve documented the process on the VoIP-Info.org Forum.

Because the Acer Chromebook was AMD-based, the installation process for Incredible PBX was much easier simply because the traditional Incredible PBX installer for Debian 10 runs without a hitch. Begin by opening the Chrome browser to chrome://flags. Enable Chrome extensions. Set Upgrade Crostini to Bullseye to Disabled. Set Debian Version to Buster. And set Allow Resizing Crostini Disks to Enabled. Restart the Chromebook to continue. Then navigate to Settings -> Advanced -> Developers -> Linux Development Environment. Set the Disk Size to 15GB. Then Enable Linux Development Environment. Once your Chromebook is restarted, run Terminal app. PIN it to task bar with Alt-Click.

Issue the following commands to install Incredible PBX for Debian 10:

sudo passwd root
# set a very secure root password
su root
cd ~
apt update
apt upgrade
apt install cron nano -y
wget http://incrediblepbx.com/IncrediblePBX2021.sh
chmod +x IncrediblePBX2021.sh
nano -w /etc/profile

Edit /etc/profile to look like this at the top. Save the file and restart your Chromebook.

Log back into your Chromebook’s Terminal app as root, and issue the following commands:

su root
cd ~
apt update
./IncrediblePBX2021.sh

Here are the remaining steps to configure Incredible PBX:

chmod 775 /
touch /var/log/auth.log
chown asterisk:asterisk /var/log/asterisk/*
Add OpenVPN client credentials as /etc/incrediblepbx.ovpn
Add gTTS following steps at this link
Run /root/enable-gmail-smarthost-for-sendmail using your Gmail app password
Remove ssh-block file from /ssh
Uncomment port with a port number above 1000 in sshd_config
Restart SSH: systemctl restart sshd
Remove UCP daemon: fwconsole setting NODEJSENABLED 0
fwconsole ma upgradeall
fwconsole reload
Clear errors, if any, from reload (several times) by doing what the prompts say
Run /root/sig-fix twice

So there you have it. A desktop demo machine in a tablet form-factor. Not to come across as an x86 snob, but there still are things we like to do on the Intel and AMD platforms that you simply cannot pull off using an ARM-based computer, at least not yet. At the top of that list is running VirtualBox. Many have tried, but VirtualBox is not an emulator. It’s a virtualization platform which means it runs other x86 applications using the existing x86 platform on which it was installed. Oracle has shown little interest in porting it to ARM processors and, even if it did so, you would only be able to run other ARM applications. As you also probably noticed, unless you find a really good sale, ARM-based Chromebooks are about $100 more expensive than their x86 competitors. So our tip of the hat goes to Acer Chromebook this time around.

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

Monday, May 30, 2022 / 12 Comments on Oracle Cloud: Grab a Free Incredible PBX Cloud Server for Life

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

Getting Started with Oracle Cloud

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

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

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

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

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

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

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

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

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

Managing Incredible PBX in the Oracle Cloud

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

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

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

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

And don’t forget to…

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

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

Set your proper timezone: ./timezone-setup

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

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

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

Using Text-to-Speech Apps in the Oracle Cloud

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

Activating IBM Text-to-Speech for Oracle Cloud

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

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

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

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

Activating Amazon’s Polly TTS for Oracle Cloud

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

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

Deploying PicoTTS in the Oracle Cloud

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

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

Activating OpenVPN Virtual Private Network

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

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

Getting Started with Incredible Fax 2021

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

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

Configuring Inbound Routes for Fax Detection

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

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

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

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

Using the GraphQL API Tool with Incredible PBX

Begin by installing the required GraphQL components:

pip3 install --pre gql[all]

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

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

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

Installing OPUS in the Oracle Cloud

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

rm /usr/lib64/asterisk/modules/codec_opus.so
rm /usr/lib64/asterisk/modules/codec_opus_open_source.so
rm /usr/lib64/asterisk/modules/res_format_attr_opus.so

How Sausage Is Made AND Special Thanks

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

Systems Integration and Public Participation with FreePBX

Monday, May 23, 2022 / 2 Comments on Systems Integration and Public Participation with FreePBX

It’s been an interesting few days in the FreePBX® VoIP community with a thread on the VoIP-Info.org and another on the FreePBX Forum. It’s prompted us to revisit what open source development is all about and what all of this means to those of you that rely upon Asterisk® and FreePBX.

After the departure of the Schmooze folks from Sangoma, virtually all development has been moved behind closed doors with the first opportunity for public participation occurring after new features appear in modules pushed to the so-called Edge repository. This is where folks can shake the kinks out of modules that presumably are almost ready for prime time. For example, take a look at the Changelog for the Framework Module. Prior to the departure of the Schmooze team, changes were managed by openly-accessible tickets. But now you will notice tickets bear a FREEI designation indicating restricted Sangoma-internal access only.

Beta previously was an appropriate moniker for these modules. If you read the FreePBX forum post above, you’ll note that now modules are being pushed to the Edge repository not only before public comment but apparently before much of any internal testing is performed by the Sangoma folks. The net result is you’d be crazy to ever use Edge modules in any production environment where, in the past, Edge modules more typically were used to fix something that was already broken in the traditional repository. Because the Bootstrap module is the lynchpin of virtually all other FreePBX modules, a recent glitch that had not been tested broke almost everything in FreePBX 16 if you happened to be using Edge modules.

I’m reminded of the old adage about marine aquariums. You never want to put a new fish in your main tank unless you’re willing to risk killing all of your other fish. This latest fiasco prompts our cautionary note about further use of the FreePBX Edge repository. Don’t load new modules on your production servers without testing them first in a VirtualBox sandbox unless you have a snapshot or backup of your server that can be deployed in minutes when something cataclysmic occurs.

And that brings us to our response concerning what Incredible PBX® is and is not all about. Going back to the early 80’s, we began tweaking hardware and software deployments to eliminate much of the pain associated with deployment of automated systems. Our friend on the VoIP-Info forum refers to Incredible PBX as a fork of FreePBX. Quite the contrary, it is anything but a fork. We use the FreePBX GPL modules exactly as they are published by Sangoma with an additional master key not controlled by Sangoma for your protection and for ours. This allows us to block specific module updates that prove to be dangerous for our users. Equally important, Incredible PBX offers improved functionality and stability, the same features that are typically associated with the work of a systems integrator… that you pay for. On the stability side, we migrated to new FreePBX repositories maintained by Clearly IP simply because the FreePBX repos had become extremely unreliable and proprietary. Sangoma deploys modules using key signatures that only they control. That means if you make any improvements or changes the FreePBX Dashboard displays all sorts of security alerts, something your customers and end-users would prefer not to see. Some of you may recall this was our primary objection to module signatures years ago.

On the enhancement side, we’ve tried to add free components that our millions of readers have clamored for. You may recall that Nerd Vittles was the first to provide turnkey Google Voice support for Asterisk over a decade ago. We then tackled security after numerous compromises of FreePBX systems around the world. Since then the list has grown exponentially. Here’s the added feature set you’ve enjoyed by deploying an Incredible PBX platform instead of the FreePBX Distro. And, unlike FreePBX commercial modules, these components won’t cost you a dime and are freely distributable. So the choice is yours.

We think the decision will be a no-brainer after your testing. For a list of all of our free VoIP solutions, visit the Incredible PBX Wiki. Enjoy!

A Walk on the Wild Side: Meet Incredible PBX for MX Linux

Monday, May 16, 2022 / 1 Comment on A Walk on the Wild Side: Meet Incredible PBX for MX Linux

This week’s adventure is just for fun. It’s a VirtualBox® Beauty featuring Incredible PBX®, Asterisk® 18, FreePBX® 15, and MX Linux 21.1. If you’re unfamiliar with MX Linux, it is one of the slickest Debian aggregations because it seamlessly integrates a desktop GUI featuring Xfce Desktop, KDE, and fluxbox into a Debian 11 platform with native support for LibreOffice, Firefox, Thunderbird, SAMBA, and some awesome games and music utilities including Clementine. If all of these apps sound like Greek, then you owe it to yourself to spend an evening or weekend exploring MX Linux while enjoying most of the integrated functionality of the Incredible PBX 2021 platform. Did we mention that printer integration is seamless with most of the major brands so you can enjoy the office suite without missing a beat by abandoning your Mac or Windows desktop.

What would we use this for? The short answer is not for production. The long answer is it’s a perfect complement for a traveling Chromebook where you want to connect back to your PBX mothership while retaining full functionality of a desktop computer back home at zero cost. VirtualBox is free. Incredible PBX is free. MX Linux including our bundled .ova image is free. And an 8GB Chromebook with 64GB of eMMC storage is dirt cheap. So what’s not to like?

Installing Oracle VM VirtualBox

Oracle’s virtual machine platform inherited from Sun is amazing. It’s not only free, but it’s pure GPL2 code. VirtualBox gives you a virtual machine platform that runs on top of any desktop operating system. In terms of limitations, we haven’t found any. We even tested this on an Atom-based Windows 7 machine with 2GB of RAM, and it worked without a hiccup. So step #1 today is to download one or more of the VirtualBox installers from VirtualBox.org or Oracle.com. Our recommendation is to put all of the 100MB installers on a 4GB thumb drive.¹ Then you’ll have everything in one place whenever and wherever you happen to need it. Once you’ve downloaded the software, simply install it onto your favorite desktop machine. Here’s a link to get VirtualBox running on a Chromebook. Accept all of the default settings, and you’ll be good to go. For more details, here’s a link to the Oracle VM VirtualBox User Manual.

NOTE: The Incredible PBX for MX Linux VM requires a VirtualBox 6.x platform. Adjust screen size in View -> Virtual Screen.

Installing the Incredible PBX for MX Linux Image

To begin, visit our SourceForge page and follow the steps to assemble the 8GB+ .ova image of Incredible PBX with MX Linux.

Next, copy it to your VirtualBox desktop machine and double-click on the Incredible PBX .ova image. Then click Import. Once the import is finished, you’ll see a new Incredible PBX for MX Linux virtual machine in the VM List of the VirtualBox Manager Window. Let’s make a couple of one-time adjustments to the Incredible PBX configuration to account for possible differences in sound and network cards on different host machines.

(1) Click once on the Incredible PBX virtual machine in the VM List. Then (2) click the Settings button. In System tab, verify Hardware Clock in UTC Time is checked. In the Audio tab, check the Enable Audio option and choose your sound card. In the Network tab for Adapter 1, check the Enable Network Adapter option. From the Attached to pull-down menu, choose Bridged Adapter. Then select your network card from the Name list. Then click OK. That’s all the configuration that is necessary.

Running Incredible PBX for MX Linux in VirtualBox

Once you’ve imported and configured the Incredible PBX for MX Linux Virtual Machine, you’re ready to go. Highlight the Incredible PBX virtual machine in the VM List on the VirtualBox Manager Window and click the Start button. The standard Linux boot procedure will begin and, within a few seconds, you’ll get the familiar Linux login prompt. Choose Other from the pull-down list and enter root for your username and password for your password.

During the bootstrap procedure, you may see a couple of dialogue boxes pop up that explain the keystrokes to move back and forth between your host operating system desktop and your virtual machine. Remember, you still have full access to your desktop computer. Incredible PBX is merely running as a task in a VM window. Always gracefully halt Incredible PBX just as you would on any computer.

Here’s what you need to know. To work in the Incredible PBX virtual machine, just left-click your mouse while it is positioned inside the VM window. To return to your host operating system desktop, press the right Option key on Windows machines or the left Command key on any Mac. On Linux desktops, press the right Ctrl key. For other operating systems, read the dialogue boxes for instructions on moving around. To access the Linux CLI, login as root with the default password: password.

Once the Xfce Desktop displays, click on the Xfce Terminal Emulator icon in the left menu bar which will drop you into the Linux CLI.

First, create a new end-user account which we will explain in a minute. Just enter the following command: adduser nerd.

Next, update your admin password for Incredible PBX web access: ./admin-pw-change.

Then update your admin password for web applications: ./apache-pw-change. You’ll need these admin passwords to access the web GUI to manage your PBX as well as to use the AsteriDex and Reminders web apps.

Finally, run ./timezone-setup to set the correct time zone for your virtual machine.

Make note of your virtual machine’s local IP and time by typing pbxstatus. You’ll need this IP address to log into the Incredible PBX GUI using Firefox on the Xfce Desktop.

Setting the Date and Time with VirtualBox

If pbxstatus still shows an incorrect time, manually set the date and time and then update the hardware clock. Here’s how assuming 05160709 is the month (May), day (16), and correct time (7:09 a.m.) of your server:

date 05160709
clock -w

Returning to the Xfce Desktop

Now let’s return to the Xfce Desktop and close the terminal window. Type exit and press ENTER.

MX Linux won’t let you run many of its desktop applications while logged in as root. To switch to the nerd user we created above, do the following. Click on the Application Menu icon in the bottom left column. Then click the Lock Screen icon at the top of the applications menu. When the familiar login screen reappears, log back into your virtual machine as nerd using the password you set up when you created the account. Now explore all the fabulous features that MX Linux offers. And follow our Incredible PBX tutorial to get up and running in minutes.

Deal of the Year: OBi2182 Color WiFi Phones now $59.99

Monday, May 9, 2022 / 1 Comment on Deal of the Year: OBi2182 Color WiFi Phones now $59.99

One year and counting… If you still have some Google Voice numbers lying around or if you’d like to join the party a little late, now is your second chance. Amazon now is selling the OBi2182 phones to U.S. residents with native Google Voice as well as WiFi, Bluetooth, HD Voice, speakerphone, and a power adapter currently selling for $69.99. Hold, transfer, and conferencing support are included in the phone. Here’s our Amazon referral link to keep the lights on.

We were big fans of OBiHai once upon a time. But then they sold out to Polycom. And they subsequently sold out to Plantronics. And support went from bad to worse along the way. But things appear to have stabilized so this offering may just be one of the best deals on the planet. Not only do you get unlimited free calling throughout the U.S., Canada, and Ukraine but you also get some of the best pricing ever on most international calls. While we no longer have any dealings with ObiHai, Polycom, or Plantronics, we know many of our followers were left high and dry when Google pulled the plug on Google Voice for Asterisk®. Here’s a tip.

Adding one or more of these phones makes a perfect supplement to your Asterisk platform making it easy to add free calling to your home or home office PBX. And it’s not too late to order a Google Voice number if you’re new to the game. Configuring a SIP or PJsip connection as well as Bluetooth connectivity to your cellphone is just as simple as adding Google Voice trunks using the OBiTalk web interface shown below. Trunk setups take less than a minute apiece. The phone supports 12 lines. And WiFi calls are crystal-clear thanks to HD Voice.

Grab an OBi2182 while you still can! An Admin Guide to the OBi2182 is available here.
