In the old days, virtual machine choices were limited to VMware, Proxmox, and VirtualBox with the first two requiring a dedicated hardware platform before you ever got started. So it looked like VirtualBox solved the problem of being able to use existing hardware for other functions as well as being able to host virtual machines. And all was well in the Intel world until Apple created its M1 chip integrating the CPU, GPU, Neural Engine, I/O, and more into a single system on a chip (SoC). Because it was based on the ARM architecture, VirtualBox no longer worked. And, despite a new beta claiming ARM compatibility, it still fails at least as a platform for Debian 11, Ubuntu 22.04, and Incredible PBX 2027.

Last week we introduced WSL, the new kid on the virtual machine block for Windows 11. And today we turn our attention to the Mac platform with Apple’s UTM offering. In a word, it’s fantastic: machine-speed virtual platforms that coexist with other Mac apps, relatively easy to install, and simple to backup and restore. So… farewell VirtualBox and hello UTM.

While UTM will run on AMD64 Macs, our focus today is the new generation of M1 and M2 Macs. There are many to choose from including multi-colored iMacs as well as MacBook Air and Pro notebooks. You won’t be disappointed by the migration. And UTM is unique in that it can reliably run both ARM applications and x86_64 apps. So let’s get started. This is a three-step process today. First, we’ll install Apple’s UTM app on your M1 or M2 machine. Second, we’ll build an Ubuntu 22.04 x86_64 platform running as a virtual machine under UTM. Third, we’ll install Incredible PBX 2027-U on the Ubuntu platform.

Before we get started, here are a couple of tips. Creating the Ubuntu 22.04 platform is a little tedious. So, once you go through the 30-minute setup process, your very next step should be to shut it down and clone it. In that way, you never have to spend time setting up the Ubuntu virtual machine platform again. You can simply reuse what you’ve already built. Our second tip is to make backups of both your original Ubuntu virtual machine AND your Incredible PBX 2027-U machine. Then store those backups off site. We’ll document the procedure below.

This is not a difficult procedure, but it has a lot of steps and takes about half an hour so hang in there and don’t skip any steps. If you’re lazy and would prefer the quick-and-dirty method to install the Ubuntu 22.04 UTM image, skip to the next section of this tutorial… but you won’t learn how to do it yourself.

1. Download the Ubuntu 22.04 Server ISO to your Desktop.

2. Open the UTM app from your Applications folder.

3. Click "Create a New Virtual Machine" icon.

4. On the Start menu, choose Emulate to emulate the AMD64 platform on your Mac M1 or M2.

5. In the Operating System menu, choose Linux. Click Browse. Select Ubuntu 22.04 ISO on your desktop. Click Continue.

6. Change the Memory setting to 2048 MB. Change CPU Cores to 2. Click Continue.

7. For the Virtual Machine Size, we recommend 20GB but the choice is yours. Click Continue.

8. On the Shared Directory menu, just click Continue.

9. On the Summary menu, check Open VM Settings. Click Save.

10. In the VM Settings, enter Incredible PBX 2027 for Name.

11. Click Network tab. Change the Network Mode to Bridged (Advanced). Click Save.

12. Start your virtual machine app by clicking on it in the Start menu.

NOTE: DO NOT MINIMIZE THE UTM APP! You’ll need to return to it and remove the ISO before reboot.

13. Click "Try to Install Ubuntu Server" to kick off the Ubuntu install.

14. After about 3 minutes of setup, the install prompts will appear.

15. Choose your Language (default English) and press ENTER.

16. Choose your Keyboard (default English US) and press ENTER.

17. In the Type Install, tab down to Ubuntu Server (minimized) and press Space Bar.
Tab down to Done and press ENTER.

18. On the Network menu, your default DHCPv4 IP address should be shown. Press ENTER.

19. On the Proxy menu, press ENTER.

20. For the Ubuntu mirror, press ENTER.

21. On the Storage Layout menu, tab to LVM option and press Space Bar.
Tab down to Done and press ENTER.

22. Review File System Summary. If all OK, press ENTER.

23. On the Confirm menu, tab to Continue and press ENTER to continue.

24. Set up your profile. We recommend:

   Your name: nerd (we’re going to destroy this account later)
   Your server name: ubuntu
   Username: nerd (we’re going to destroy this user account later)
   Password: password (type it twice)

   Tab to Done and press ENTER.

25. If you want to pay for Ubuntu Pro, you can do it on the next screen.
Otherwise, press ENTER.

26. On the SSH Setup menu, press space bar to enable SSH. Tab to Done. Press ENTER.

27. On Server Snaps menu, use the Down cursor to scroll to Done and press ENTER.

28. You’re now at the 15-minute mark and the screen will say Install complete! It’s not.
The Ubuntu install will now continue in unattended mode. Have a cup of coffee.
Return in about 7 minutes and await the Reboot Now prompt at the bottom of the screen.

29. Press ENTER and immediately switch back to the UTM app’s Main Menu.

30. Scroll down to CD/DVD line and click the Option bar and choose Clear.

31. UTM will now reboot into your new Ubuntu server.

   If it redisplays the initial Ubuntu install menu, verify Step #30 completed.
   Then kill the virtual machine and restart it.

32. Log in as nerd with the password you set up above.

33. Now set up a password for the root user:

   sudo passwd root

34. Log out as user nerd: exit

35. Login as root.

36. Remove the nerd user account:

   userdel -r nerd

37. Install the nano editor:

   apt install nano -y

38. Edit the sshd_config file to allow remote root SSH access:

   nano -w /etc/ssh/sshd_config

39. Adjust and uncomment the following settings:

   PermitRootLogin yes
   PasswordAuthentication yes

   Save the file: Ctrl-X, Y, then ENTER

40. Restart SSH: systemctl restart ssh

Now you’re ready to install Incredible PBX 2027-U. But, before you do anything else, shutdown the VM. Then right-click on the VM and choose Clone to make a duplicate. Now fire up the duplicate and install Incredible PBX 2027-U by following the steps in our current tutorial.

If you completed the steps above, you can skip this section. But, if Lazy is your middle name, here’s an alternate method that saves you some time. Begin by downloading the ubuntu2204utm.tar.gz file from our Incredible PBX repo to your Desktop. Then run the Terminal app and issue the following commands:

cd ~/Library/Containers/com.utmapp.UTM/Data/Documents
tar zxvf ~/Desktop/ubuntu2204utm.tar.gz

Now run the UTM app. Then start the Ubuntu 22.04 virtual machine. Login as root with default password of password. Now begin the Incredible PBX 2027-U install procedure as documented in our tutorial here.

If you would prefer to build your Incredible PBX 2027 server on the Debian 11 platform, begin by downloading the debian116utm.tar.gz file from our Incredible PBX repo to your Desktop. Then run the Terminal app and issue the following commands:

cd ~/Library/Containers/com.utmapp.UTM/Data/Documents
tar zxvf ~/Desktop/debian116utm.tar.gz

Now run the UTM app. Then start the Debian 11.6 virtual machine. Login as root with default password of password. Now begin the Incredible PBX 2027-D install procedure as documented in our tutorial here.

The trick to backing up and transferring an existing UTM image is to create a tarball of the desired .utm directory in ~/Library/Containers/com.utmapp.UTM/Data/Documents. The ubuntu2204.tar.gz file is about 2 gigabytes in size. Then untar it on the target platform in the same directory after installing the UTM app on that platform. It’s quite difficult to navigate to this directory with Finder so you’re better off using Terminal. The only other wrinkle after transferring a backup image to an Intel Mac is you’ll have to edit the UTM’s Network setting (right-click on .utm app in UTM GUI). Adjust the setting to match your new platform. So, on your target machine, run ifconfig and decipher the name of the adapter that actually shows your machine’s LAN IP address. It was en0 on our MacBook Air M1 and en1 on our old iMac Intel machine. YMMV.

TIPS: If you want LAN access to the virtual machine from devices other than the Mac on which the VM is installed, you’ll need to edit the UTM, click +New in the Devices section of the Edit menu and choose Network. Click Save to update settings. This will enable Shared Network Mode in addition to Bridged Mode, and a LAN IP address will be assigned on VM restart. When first logging into virtual machine, do NOT issue the unminimize command.

We will keep everyone posted on further developments.
 

Lo and behold, Microsoft was offering their Windows Subsystem for Linux GUI (WSLg) on GitHub. You may recall that we introduced a Debian 10 offering for this platform in July, 2022. Unfortunately, "improvements" in the WSLg platform appear to have permanently broken that offering. But, hope springs eternal, and today we’re pleased to introduce Incredible PBX 2027 for WSLg running on their Ubuntu 22.04 platform. You can read all about the lengths to which Microsoft has gone to integrate WSLg into Windows 11 here.

In our original article we provided a referral link to this (now updated) tiny, $220 Windows 11 powerhouse. These referral commissions help keep the lights on at Nerd Vittles. But any Windows 11 hardware will work just fine. In fact, our current favorite that we personally use is this Windows 11 Acer notebook that currently sells for $519 with a whopping 20 gigs of RAM, a one terabyte NVMe SSD, and every bell, whistle, and port you could ever want. But we digress. Today we’re installing Incredible PBX 2027-U on the Windows 11 WSL platform.

To get started, you’ll need Windows 11 (build 22000.*) or Windows 11 Insider Preview (builds 21362+) using any hardware platform that supports Windows 11. To begin, from the Windows 11 Start Menu, Search for powershell. Right click on the 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 an Ubuntu Virtual Machine: wsl --install -d Ubuntu-22.04. 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 Ubuntu-22.04 app from the Start menu. That will straighten things out. Once the Ubuntu CLI window appears, enter the following commands to set up the root user account and begin your Incredible PBX install. Then go have a very long cup of coffee.

sudo passwd root
su root
# enter password you created for root
cd ~
apt install wget -y
wget http://incrediblepbx.com/IncrediblePBX2027-U-Win11.sh
chmod +x IncrediblePBX2027-U-Win11.sh
./IncrediblePBX2027-U-Win11.sh

While you’re waiting, notice that the Windows Start Menu now includes a new Ubuntu app which you will use to launch the Incredible PBX 2027-U virtual machine down the road.

When the install finishes, reboot.

Keep in mind that Incredible PBX will be running as an Ubuntu-22.04 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 your MySQL databases.

To start the Ubuntu-22.04 virtual machine, you can do it in either of two ways. From the Windows Start Menu, double-click on the Ubuntu-22.04 app. Or from the PowerShell running as Administrator, type: wsl -d Ubuntu-22.04. Verify it’s running like this: wsl -l -v

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

su root
# enter root password
cd ~
./update-IncrediblePBX
pbxstatus
# if pbxstatus shows non-fax apps down 
# then run startup below
./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 172.19.180.143 is the LAN address shown in pbxstatus:

ssh root@172.19.180.143

To shutdown the Ubuntu-22.04 virtual machine, first open the Ubuntu-22.04 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 Ubuntu-22.04

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 Ubuntu .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

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

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

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.

Adding a Destination for Blacklisted Calls. The first time you log into the FreePBX GUI with your admin credentials using a web browser, you will be prompted to enter a destination for blacklisted callers. Navigate to Admin -> Blacklist -> Settings in the GUI and enter a Destination for Blacklisted Callers. We recommend Extension 53669. That’s our buddy, Lenny, who is great with spammers. Then clear the message from the Dashboard Overview.

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

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

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

Here are some numbers to try:

123 - Reminders
947 - Weather by ZIP Code (requires keyboard entry of ZIP code)
951 - Yahoo News
TODAY - Today in History
LENNY - The Telemarketer's Worst Nightmare

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

It’s a good idea to check back here regularly for any late-breaking bug fixes. Here’s the first one, and it involves remote SSH connections using Ubuntu 22.04. It appears to be more prevalent where one or both ends of the connection are wireless. If you experience delays in the SSH connection, try this syntax where 10.8.xx..yy is your server’s private OpenVPN IP address:

ssh -o IPQoS=none root@10.8.xx.yy
