The 5-Minute PBX: A Fresh Look at Oracle’s VirtualBox with Incredible PBX

Today we’re paying another visit to our favorite virtual machine platform and introducing four new VoIP images that let you compare features and performance of Asterisk® 11 running atop Ubuntu® 14 or Scientific Linux™ 6.5 with FreePBX® 2.11 or the just-released version 12 release candidate. Think of Incredible PBX™ as the VoIP glue stick that assembles all the necessary VoIP components and holds them together seamlessly. As with all Incredible PBX builds, you also get the full complement of goodies including dozens of text-to-speech apps, voice dialing, SMS messaging, fax support, reminders and wakeup calls, and SECURITY! The difference with the VirtualBox® platform is you get a turnkey install of everything on any desktop computer in less than 5 minutes! That includes Windows PCs, Macs, Linux desktops, and even Solaris machines.

Is VirtualBox merely a sandbox for experimentation? Absolutely not. With any of the beefier desktop computers available today, running Incredible PBX as a 24/7 VirtualBox image is every bit as feature rich with stellar performance that’s equivalent to using dedicated hardware. And there are some added advantages. Obviously, deploying a turnkey VoIP platform in under 5 minutes is a major plus. But, unlike using a dedicated Linux platform, you also get the ability to take snapshots of your system and do full backups in minutes instead of the hours required to bring down dedicated hardware, load a different backup application using a different operating system, perform a backup, and then reboot your VoIP server. And your backups won’t just run on the one server on which the backup was performed. You can restore the backup to any other computer that can run VirtualBox. For any of you that came from a network management background, you know what a big deal that really is. And there’s one more bonus. With Incredible Backup and Restore, you can move your image to dedicated hardware running the same operating system with Asterisk 11 and the same version of FreePBX in minutes.

Need to deploy VoIP servers at dozens of sites around the globe? Not a problem with VirtualBox. Just send a preconfigured VirtualBox image to each site and install VirtualBox on a local desktop computer. In 5 minutes, you have a functional VoIP server including interconnectivity to all of your other VoIP servers with a virtual private network already in place to provide secure VoIP connectivity between all of your sites.

Are there security compromises using the VirtualBox platform? Not at all. Incredible PBX still comes preconfigured with the Linux IPtables firewall that is locked down to a whitelist of local area networks, preferred providers, and your own IP addresses. You can expand the whitelist using the add-ip and add-fqdn scripts or use PortKnocker and Travelin’ Man 4 tools to let remote users gain instant access.

Why four different Incredible PBX images? Glad you asked. Ubuntu and Scientific Linux are a bit like French and Spanish. They’re both languages for communicating, but many of the words are different. Some prefer one or the other so now you have a choice. As for the FreePBX options, let us put in a plug for the FreePBX 12 release candidate. The FreePBX Dev Team has invested thousands of hours in this new software. It shows! Please take it for a spin and give the developers some feedback. To move to Asterisk 12 and 13, you’re going to need FreePBX 12 so you might as well start getting used to it. While there are many similarities in the user interface, the under-the-covers work that the FreePBX team has invested in this new product is nothing short of amazing. There’s very little of the FreePBX 2.11 code that hasn’t been either cleaned up or completely rewritten. We think you’ll like it so give it a try. Those that need a production environment probably should stick with FreePBX 2.11 for the time being. The new Virtual Box images also give you an opportunity to compare performance between the two operating systems and the two FreePBX versions. This isn’t 1999. Take advantage of the opportunity. It only takes a few minutes to spin up a new virtual machine and go for a test drive.

Getting Started. For today, we’ll provide a refresher course on loading VirtualBox and one of the Incredible PBX virtual images. Then we want to spend a little time explaining the secret sauce that goes into building these images so that you can do it yourself either to migrate to a different network or to deploy at multiple sites. When we’re finished, you’ll know everything we’ve learned about deploying VirtualBox machines and, unlike Grandma, we won’t leave an important ingredient out of the recipe just to be sure you never forget how good Grandma’s cookies really were. So let’s get started.

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. 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.

Downloading the Incredible PBX Virtual Machines

A word of warning on the front end. Incredible PBX images featuring Asterisk 11 for VirtualBox are huge! The two Ubuntu images for FreePBX 2.11 and 12 are 1.5GB. The two Scientific Linux 6.5 images for FreePBX 2.11 and 12 are 2.3GB. We’ve added SourceForge hotlinks. So simply click on the desired images and download them to your desktop. Then go to lunch.

Importing & Configuring Incredible PBX Virtual Machines in VirtualBox

You only perform the import step one time. Once imported into VirtualBox, Incredible PBX is ready to use. There’s no further installation required, just like an OpenVZ template… only better. Double-click on the .ova file you downloaded to begin the procedure and load it into VirtualBox. When prompted, be sure to check the Reinitialize the Mac address of all network cards box and then click the Import button. Once the import is finished, you’ll see a new Incredible PBX virtual machine in your VM List on the VirtualBox Manager Window. We need to make a couple of one-time adjustments to the Incredible PBX VM configuration to account for differences in sound and network cards on different host machines.

Click on the Incredible PBX Virtual Machine in the VM List. Then click Settings -> Audio and check the Enable Audio option and choose your sound card. Save your setup by clicking the OK button. Next click Settings -> Network. 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. Finally, click Settings -> System, uncheck Hardware clock in UTC time, and click OK. That’s all the configuration that is necessary for your Incredible PBX Virtual Machine. The rest is automagic.

Running Incredible PBX Virtual Machines in VirtualBox

Once you’ve imported and configured the Incredible PBX Virtual Machine, you’re ready to go. Highlight IncrediblePBX Virtual Machine in the VM List on the VirtualBox Manager Window and click the Start button. The boot procedure with your chosen operating system will begin just as if you had installed Incredible PBX on a standalone machine. You’ll 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 VirtualBox window. Always gracefully halt Incredible PBX just as you would on a dedicated 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. 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. To access FreePBX with a browser, point to the IP address of your virtual machine and login as admin with admin password set below. For the security of your server, we recommend that you log in to the Linux CLI at least once a week so that Incredible PBX updates get applied to your server regularly. This is critically important if you care about your phone bill.

When logging in for the first time, Incredible PBX will go through some setup steps and then reboot. Login again to complete the setup. status will always provide a snapshot of your system. To shut down Incredible PBX gracefully, click in the VM window with your mouse, log in as root, and type: halt. Be sure to complete the following setup steps from the Linux CLI:

  • Change your root password: passwd
  • Set your FreePBX admin password: /root/admin-pw-change
  • Set your correct time zone: /root/timezone-setup
  • Add WhiteList entries to firewall if needed: /root/add-ip or /root/add-fqdn
  • Store PortKnocker credentials in a safe place: cat /root/knock.FAQ
  • Enable SAMBA if desired: /root/samba-enable.sh
  • Enable Incredible Fax support if desired: (script in /root)
  • Login to your NeoRouter VPN server if desired: /root/nrclientcmd

Preparing Incredible PBX Virtual Machines for Migration

As the Linux operating systems have become more turnkey, one of the shortcuts that has been implemented on both the RedHat and Debian/Ubuntu platforms is storage of your network setup so that the server reboots more quickly. While that’s fine for rebooting on the same server, it’s a real problem if you attempt to move your setup to different hardware or a new network because eth0 will not load. That means no IP address! Here are two ways to assure that things will actually work after the move. Both assume that you will have a DHCP server at the new location just as you did at your existing site.

The Easy Way. If you have console access after the VM image is restored on the new platform (which means you don’t need a network IP address for the server in order to log in as root), then the easy way to prepare any of the Incredible PBX machines for relocation is to issue the following commands before you halt the system and make a VirtualBox backup:

touch /etc/update_hostconfig
touch /etc/update_serverconfig

Once you have halted the server, edit both the sound card and network card settings and disable both of them in VirtualBox Manager. Then choose File -> Export Appliance from the VirtualBox title bar and create a .ova backup image on your desktop. You now have an image that is similar to the Incredible PBX image that you originally downloaded, except it has all of your data and settings. All you have to do is repeat the install drill above at the new location using the .ova image you created and log in with whatever your current root password happens to be. You’ll get a two-pass automatic setup just as you did when you began today’s adventure.

The only drawback to this procedure is the fact that the extension 701 and default DISA passwords will be initialized when you first boot from your .ova image at the other location. Aside from that, you’ll have a clean platform with new SSH and DUNDI credentials as well as mostly sanitized log files.

The Hard Way. The other alternative is to manually prepare your existing system for migration before you shut it down. The primary reason for doing this would be to assure that you can log in with an SSH client at the other end as soon as the server is booted. The steps differ a bit depending upon whether you’re on the Ubuntu or Scientific Linux platform. But on both platforms you need to enter the IP address from which you will log in at the new site unless it is on one of the private LAN subnets that already is whitelisted in IPtables. Just issue the command /root/add-ip and choose 0 option to enable all services for the new IP address. Then…

On the Ubuntu platform, issue the following commands:

touch /etc/update_hostconfig
touch /etc/update_serverconfig
rm -f /var/lib/dhcp/*
rm -f /etc/udev/rules.d/70*
halt

On the Scientific Linux platform, issue the following commands:

touch /etc/update_hostconfig
touch /etc/update_serverconfig
rm -f /var/lib/dhcpd/*
rm -f /var/lib/dhclient/*
rm -f /etc/udev/rules.d/70*
halt

Once you have halted the server, edit both the sound card and network card settings and disable both of them in VirtualBox Manager. Then choose File -> Export Appliance from the VirtualBox title bar and create a .ova backup image on your desktop. Now you’re an expert. Enjoy!

The 5-Minute PBX: PIAF-Green Virtual Machine for Windows, Mac, or Linux

In our never-ending trek to build the Perfect PBX™, we have a sneak peek for you today of the soon-to-be-released PBX in a Flash™ 2.0.6.4.5 featuring CentOS® 6.4 LAMP stack (32-bit), Asterisk® 11.5.1, and FreePBX® 2.11.0.11. The 2.0.6.4.5 release also has a number of new security patches including a new Linux kernel that’s been patched to eliminate the reported zero-day vulnerability. Once you download today’s appliance, you can have a turnkey PBX running under VirtualBox® on almost any desktop computer in less than 5 minutes. We’re not talking about a crippled telephony platform with limited functionality. What you’ll have is the same platform that hundreds of thousands of organizations use to run their corporate phone systems. And, if you want the Incredible PBX™ feature set with literally dozens of open source telephony applications including news, weather, stocks, tide reports, SMS messaging, free faxing with Incredible Fax™, telephone reminders, wakeup calls, and more then just add a couple minutes to run two one-click installers. Welcome to the world of open source!

The real beauty of PBX in a Flash has not been that someone with sufficient expertise couldn’t assemble something just as good or even better. Watch some of the AstriCon presentations if you have any doubts. The beauty of PIAF is it puts this technology down where the goats can get it. It provides a toolset that encourages further development by simplifying the learning curve for a broad cross-section of the VoIP community while not compromising functionality or flexibility. The source code for the major components is included in the build so you can customize and recompile Asterisk or load a new version of Asterisk or any additional Linux app in minutes without losing your existing setup.

If Voice Over IP technology is Greek to you, here’s a new 60-minute video tutorial that will tell you everything you need to know about this exciting, new technology before you begin the actual installation process:


As many of you know, we have literally hundreds of gurus on the PIAF Forum. That doesn’t mean any particular person or group knows everything. It’s merely a designation that a particular individual is an expert at something. The collective wisdom of the group is what makes PBX in a Flash as a project better because we’ve put in place a platform that experts from many different disciplines can build upon without needing to learn everything about everything. Simply stated, you can be a terrific chef without knowing how to build a stove!

Turning to Asterisk® 11 and FreePBX® 2.11, these releases are a remarkable step forward both in terms of toolset and in the amazing stability of the platform. For our part, we want to get our latest release of PBX in a Flash with CentOS 6.4, Asterisk 11.5.1 and FreePBX 2.11 release into as many hands as possible with a near zero investment in hardware and setup time.

The Ultimate VoIP Appliance: PIAF Virtual Machine for VirtualBox

Today brings us to a new plateau in the virtual machine development era. Thanks to the masterful work of Tom King on PBX in a Flash 2.0.6.4.5, we’re pleased to introduce a new product that can be installed in under 5 minutes and will run on any Windows PC, Mac, or Linux machine as well as Solaris. And, unlike the dedicated machine platforms and OpenVZ compromises of years past, today’s PIAF-Green Virtual Machine is state-of-the-art giving you everything a bare metal install from source code would have provided. Most importantly, the components are truly portable. They can be copied to a 4GB flash drive1 for the price of a good hamburger and installed from there onto any type of machine that happens to be in front of you. Five minutes later, you have a fully functional Asterisk server with FreePBX and exactly the same feature set and source code that you would have had doing a bare metal PIAF install to a dedicated server. And we’ve built this 32-bit production-ready PIAF-Green Virtual Machine with Asterisk 11.5.1 and FreePBX 2.11. No Internet access required to perform the install. Sound too good to be true? Keep reading or, better yet, try the PIAF appliance for yourself. The install process is simple:

  1. Download and install VirtualBox onto a Desktop Machine of your choice
  2. Download and double-click on the PIAF-Green Virtual Machine to import it into VirtualBox
  3. Select the PIAF-Green Virtual Machine in VirtualBox Manager Window and click the Start button

Introducing Oracle VM VirtualBox

We’re late to the party, but Virtual Box®, Oracle’s virtual machine platform inherited from Sun, is really something. 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 is to download one or more of the VirtualBox installers from VirtualBox.org or Oracle.com. As mentioned, our recommendation is to put all of the 100MB installers on a 4GB thumb drive. 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. 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.

Installing the PIAF Virtual Machine

Step #1 is to download the PIAF-Green Open Virtualization Appliance (.ova) from SourceForge.

Step #2: Verify the checksums for the 32-bit .ova appliance to be sure everything got downloaded properly. To check the MD5/SHA1 checksums in Windows, download and run Microsoft’s File Checksum Integrity Verifier.

For Mac or Linux desktops, open a Terminal window, change to the directory in which you downloaded the .ova file of your choice, and type the following commands:

md5 PIAF-Green-32.ova (use md5sum for Linux)
openssl sha1 PIAF-Green-32.ova

The correct MD5 checksum for PIAF-Green-32.ova is 7691127afd065412e40429cee49a4738. The correct SHA1 checksum for PIAF-Green-32 is 9b3828649dc9644d046ef83cb227aea4c1473c65.

Step #3: Double-click on the downloaded .ova file which will begin the import process into VirtualBox. It only takes a couple minutes, and you only do it once. IMPORTANT: Be sure to check the Reinitialize the Mac address of all network cards box before clicking the Import button.

Once the import is finished, you’ll see a new PIAF virtual machine in the VM List of your VirtualBox Manager Window. You’ll need to make a couple of one-time adjustments to the PIAF-Green Virtual Machine configuration to account for differences in sound and network cards on different host machines.

Click on the PIAF-Green Virtual Machine in the VM List. Then click Settings -> Audio and check the Enable Audio option and choose your sound card. Save your setup by clicking the OK button. Next click Settings -> Network. 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 ever necessary for your PIAF-Green Virtual Machine. The rest is automagic.

Running the PIAF Virtual Machine in VirtualBox

Once you’ve imported and configured the PIAF Virtual Machine, you’re ready to go. Highlight PIAF Virtual Machine in the VM List on the VirtualBox Manager Window and click the Start button. The PIAF boot procedure with CentOS 6.4 will begin just as if you had installed PBX in a Flash on a standalone machine. You’ll 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 PIAF VM.

Here’s what you need to know. To work in the PIAF 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. For other operating systems, read the dialogue boxes for instructions on moving around. Always shut down PIAF gracefully! Click in the VM window with your mouse, log in as root, and type: shutdown -h now.

Run the PIAF Virtual Machine behind a hardware-based firewall with no Internet port exposure!

To begin, position your mouse over the VM window and left-click. Once the PIAF VM has booted, log in as root with password as the password. Change your root password immediately by typing passwd at the command prompt. Now set up a secure maint password for FreePBX as well. Type passwd-master. If you’re not in the Eastern U.S. time zone, then you’ll want to adjust your timezone setting so that reminders and other time-sensitive events happen at the correct time. While logged into your server as root, issue this command:

/root/timezone-setup

Next, use a browser to log into your PIAF server by pointing to the IP address of the PIAF VM that’s displayed in the status window of the CLI. Click on the User button to display the Admin choices in the main PIAF Menu. Click on the FreePBX option to load the FreePBX GUI. You will be prompted for an Apache username and password. For the username, use maint. For the password, use whatever password you set up with passwd-master.

Now read the latest PIAF Quick Start Guide and begin your VoIP adventure. Then you’ll want to do some reading on VirtualBox. We’ve barely scratched the surface. Setting up Headless VMs that run in the background on any server is a breeze. From the command line, here’s an article to get you started. But you also can start Headless VMs from within the GUI by highlighting the VM and clicking Shift->Start. Always shut down VMs gracefully: Close->ACPI Shutdown. You’ll find more great tips at virtualbox.org and GitHub.

One of the real beauties of VirtualBox is you don’t have to use a GUI at all. The entire process can be driven from the command line. Other than on a Mac, here is the procedure to import, configure, and run the PIAF-Green-32 Virtual Machine:
 
VBoxManage import PIAF-Purple.ova
VBoxManage modifyvm "PIAF-Green-32" --nic1 nat
VBoxManage modifyvm "PIAF-Green-32" --acpi on --nic1 bridged
VBoxHeadless --startvm "PIAF-Green-32" &
# Wait 1 minute for PIAF-Green to load. Then decipher IP address like this:
VBoxManage guestproperty get "PIAF-Green-32" /VirtualBox/GuestInfo/Net/0/V4/IP
# Now you can use SSH to login to PIAF-Green at the displayed IP address
# Shutdown the PIAF-Green Virtual Machine with the following command:
VBoxManage controlvm "PIAF-Green-32" acpipowerbutton

On a Mac, everything works the same way except for deciphering the IP address. Download our findip script for that.

Adding Incredible PBX 11 and Incredible Fax

You can read all about the Incredible PBX 11 and Incredible Fax feature set in our recent Nerd Vittles article. If you decide you’d like to add one or both to your PIAF-Green Virtual Machine, just log into your server as root and issue the following commands. NOTE: You must install Incredible Fax after installing Incredible PBX, or you will lose the ability to install Incredible PBX at a later time. With Incredible Fax, there are a number of prompts during the install. With the exception of the prompt asking for your local area code, just press Enter at every other prompt.

cd /root
wget http://incrediblepbx.com/incrediblepbx11.gz
gunzip incrediblepbx11.gz
chmod +x incrediblepbx11
./incrediblepbx11
./incrediblefax11.sh

The 5-Minute PBX: Introducing PIAF-Green Virtual Machine for VMware ESXi

In our never-ending trek to build the Perfect PBX™, we have another installment for you today featuring VMware’s just released vSphere Hypervisor 5.5 (ESXi). And, yes, there’s still a free ESXi version with a free license available here. But, unlike VirtualBox, you’ll need a dedicated (beefy) server on which to install ESXi. Be sure to register on the site and obtain then install the unrestricted license, or you’re SOL after the short eval period. We’ve built an ESXi appliance which installs in under 5 minutes featuring the latest, greatest PIAF-Green with a CentOS® 6.4 LAMP stack (32-bit), Asterisk® 11.5.1, and FreePBX® 2.11. This 2.0.6.4.4 release also has a number of new security patches including a new Linux kernel that’s been patched to eliminate the reported zero-day vulnerability. If this is your first experience with our virtual machine builds, we’re not talking about a crippled telephony platform with limited functionality.

The Ultimate VoIP Appliance: PIAF-Green Virtual Machine for ESXi

Today brings us to yet another plateau in the virtual machine development era. Because most major companies already have a VMware platform in place, we’ll begin by walking you through the 5-minute exercise to install the PIAF-Green appliance. If you’re new to VMware and want to deploy an EXSi server on which to run PIAF-Green, then skip over the PIAF-Green install procedure for the time being. Jump down to the section where we walk you through bringing up your own ESXi server, and then return here once your ESXi server is humming along. Let us hasten to add that we make no claims with regard to VMware expertise. If you need help with VMware, head over to the PIAF Forum and chat with our VMware gurus. We’re not one of them.

To install the PIAF-Green Virtual Machine for ESXi, there are six simple steps:

  1. Download the ESXi PIAF-Green .ova template from SourceForge
  2. Verify checksums for downloaded ESXi PIAF-Green .ova template
  3. Deploy the PIAF-Green Template on ESXi using vSphere Client
  4. Start PIAF-Green appliance
  5. Login using Virtual Machine Console
  6. Complete the PIAF-Green Setup Checklist

Installing the PIAF-Green Virtual Machine for ESXi

1. Download the PIAF-Green Open Virtualization Appliance (.ova) for ESXi from SourceForge. Do not confuse it with our OVA appliance for VirtualBox. They’re not the same!

2. Verify the checksums for the 32-bit .ova appliance to be sure everything got downloaded properly. To check the MD5/SHA1 checksums in Windows, download and run Microsoft’s File Checksum Integrity Verifier.

For Mac or Linux desktops, open a Terminal window, change to the directory in which you downloaded the .ova file of your choice, and type the following commands:

md5 PIAF-Green-32.ova (use md5sum for Linux)
openssl sha1 PIAF-Green-32.ova

The correct MD5 checksum for PIAF-Green-32.ova is 2ba3a84d3be3167274308342f73a7a1f. The correct SHA1 checksum for PIAF-Green-32 is b79f2a96b65465337ddda5426e4a8d63982651ad. The bold portion isn’t actually shown in the i file display on SourceForge. Don’t worry about it.

3. To deploy the template on your ESXi server, open vSphere Client on your Windows desktop. Click File -> Deploy OVF Template as shown below. Browse to the location of your downloaded template and select it. Give the virtual machine a unique name (you can have multiple VMs using the same template). Accept the Disk Format defaults and click Finish to begin the import.

Once the import is finished, you’ll see a new PIAF-Green virtual machine in the Inventory under the IP address of your ESXi server.

4. Start up the new virtual machine by highlighting it and clicking Power on Virtual Machine in the right pane of vSphere Client. You can see it at the bottom of the screenshot below.

5. Open the Virtual Machine Console by clicking on the icon as shown below. Use your mouse to click inside the console window once it opens. Then log in as root with the default password: password.

HINT: To exit from the VM Console window, press Ctrl-Alt simultaneously.

PIAF-Green Virtual Machine Setup Checklist for ESXi

Once you’ve logged into PIAF-Green, you’ll see the status window telling you what’s running and what’s not. It should look something like what’s shown below. It includes the IP address of your virtual machine. This can be used with SSH to log in from any computer on your LAN. It also is required information to log in to the PIAF and FreePBX GUIs using a browser.

Here’s what you need to know. To work in the PIAF Virtual Machine from the vSphere Console, just left-click your mouse while it is positioned inside the VM Console window. To return to your host operating system desktop, press Ctrl-Alt. Remember to always shut down PIAF gracefully! Click in the VM Console window with your mouse, log in as root, and type: shutdown -h now.

Run ESXi and Virtual Machines behind a hardware-based firewall with no Internet port exposure!

Here’s the quick PIAF Setup Checklist:

  1. Change your root password immediately by typing passwd
  2. Set up a secure maint password for FreePBX: passwd-master
  3. Adjust your timezone setting: /root/timezone-setup
  4. Decipher your PIAF-Green VM’s IP address: status
  5. Browser log into PIAF: Point to IP address of PIAF-Green VM
  6. Click on User button to display the PIAF Admin menu
  7. Click on the FreePBX icon to load FreePBX GUI
  8. When prompted for Apache username and password: Username=maint
  9. Password is whatever password you set up with passwd-master

Now read the latest PIAF Quick Start Guide and begin your VoIP adventure.

You can read all about the Incredible PBX 11 and Incredible Fax feature set in our recent Nerd Vittles article. If you decide you’d like to add one or both to your PIAF-Green Virtual Machine, just log into your server as root and issue the following commands. NOTE: You must install Incredible Fax after installing Incredible PBX, or you will lose the ability to install Incredible PBX at a later time. With Incredible Fax, there are a number of prompts during the install. With the exception of the prompt asking for your local area code, just press Enter at every other prompt.

cd /root
wget http://incrediblepbx.com/incrediblepbx11.gz
gunzip incrediblepbx11.gz
chmod +x incrediblepbx11
./incrediblepbx11
./incrediblefax11.sh

The Incredible PBX 11 Inventory. For those that have never heard of The Incredible PBX, here’s the current 11.0 feature set in addition to the base install of PBX in a Flash with the CentOS 6.4, Asterisk 11, FreePBX 2.11, and Apache, SendMail, MySQL, PHP, phpMyAdmin, IPtables Linux firewall, Fail2Ban, and WebMin. Incredible Fax, NeoRouter and PPTP VPNs, and all sorts of backup solutions are still just one command away and may be installed using the scripts included with Incredible PBX 11 and PBX in a Flash. Type help-pbx and browse /root for dozens of one-click install scripts.

Unlike the dedicated machine platforms and OpenVZ compromises of years past, today’s PIAF-Green Virtual Machine is state-of-the-art giving you everything a bare metal install from source code would have provided. Most importantly, the components are truly portable. They can be exported and copied to an external USB drive or flash drive for instant portability for use on any ESXi server.

Installing VMware Tools (optional). If you wish to install VMware Tools in your Virtual Machine, here’s the two-step procedure. First, enable the tools in vSphere Client: VM -> Guest -> Install VMware Tools. See image below. Then log in to your virtual machine in the console and issue the following commands:

cd /mnt
mkdir cdrom
mount /dev/cdrom /mnt/cdrom
cd /tmp
tar zxvf /mnt/cdrom/VMware*
cd vmware-tools-distrib
./vmware-install.pl

Introducing vSphere Hypervisor 5.5 (ESXi)

We’re late to the party (again), but VMware’s latest ESXi platform is quite impressive. Because there’s a free version, we wanted to walk through the installation scenario just in case you have a spare (beefy) server sitting around gathering dust. Security is always our primary concern, and you are well-advised to install ESXi behind a secure, hardware-based firewall with no Internet port exposure to your ESXi server or its virtual machines!

There are dozens of VMware products and add-ons for the ESXi platform. Almost all of them cost money, lots of it. If your company is considering a move to VMware, then the free ESXi platform is a good way to get your feet wet. Before you make purchasing decisions, you really need to hire a VMware consultant. It could save you tens of thousands of dollars.

For today, our focus is getting a free ESXi platform in place to run PBX in a Flash virtual machines. Here’s what you’ll need: a server, the vSphere Hypervisor 5.5 ESXi ISO, a free license for ESXi, and the vSphere Client for Windows. All are free, but you do have to register for an account on the VMware web site. A web client is also available for dedicated Mac and Linux users. See the VMware site for details.

ESXi comes with a short-term license to let you try the application. Once you register for an account on the VMware web site, you also can obtain a full license here at no cost. Don’t put it off. Once your short-term eval license expires, you’re dead in the water unless you previously have installed the free, unrestricted license.

Installing ESXi. Here are the steps to get yourself in the (free) ESXi business:

  1. Download the ESXi ISO and burn it to a CD/DVD
  2. Obtain permanent license key from VMware
  3. Boot your server from the CD and answer the (easy) prompts
  4. When install finishes, remove CD and reboot
  5. Start up ESXi and log in as root with your new password
  6. Write down the IP address of your server
  7. Your temporary license key (only) is now active
  8. Using a browser, access your ESXi server by its IP address
  9. Click on the provided link to download and install the vSphere Client
  10. Open vSphere Client on Windows Desktop and login as root with same password

Registering Your ESXi License Key. Once the vSphere Client is open on your desktop…

  1. Select Configuration tab
  2. Click Software and choose Licensed Features
  3. Click Edit link in the top right hand corner as shown below
  4. Choose: Assign a new license key to this host
  5. Enter the license key you obtained from VMware
  6. Click OK to save your changes
  7. Make sure your key was accepted and is displayed

Getting Support. If you need help or have tips with regard to this tutorial, please visit this thread on the PIAF Forum and post your comments. Enjoy!

Deals of the Week. There are a couple of amazing deals still on the street, but you’d better hurry. First, for new customers, Sangoma is offering a board of your choice from a very impressive list at 75% off. For details, see this thread on the PIAF Forum. Second, a new company called Copy.com is offering 20GB of free cloud storage with no restrictions on file size uploads (which are all too common with other free offers). Copy.com has free sync apps for Windows, Macs, and Linux systems. To take advantage of the offer, just click on our referral link here. We get 5GB of extra storage, too, which will help avoid another PIAF Forum disaster.

The Next Plateau: VoIP Communications with Asterisk in Amazon’s EC2 Cloud


We’ve spent considerable effort exploring and enhancing the VoIP cloud offerings for our followers, and today we’re delighted to introduce another terrific service: Amazon’s Elastic Compute Cloud (EC2). This is one of several Amazon Web Service (AWS) offerings that provides resizable compute capacity in the cloud and is designed to make web-scale computing easier for developers. That’s the Amazon pitch for their service. Ours is a bit different. For anyone with mission-critical operations or that has ever given a moment’s thought to business continuity planning (THINK: hurricanes, tornados, earthquakes, blizzards, fires, floods, bombs), you need an EC2 backup plan for VoIP communications. It really doesn’t matter whether your organization uses a proprietary phone system, or Asterisk®, or good ol’ black telephones, the point is simply this. When your lights go out and you still need a communications system for your employees and your customers, what’s your plan? Staying home in bed isn’t a choice for most folks. So our focus is not to persuade anybody to move their primary communications platform to Amazon EC2 although it’s certainly worth considering. For today, let’s tackle emergency planning and Disaster Recovery 101 for that dreadful day when you really don’t have a choice. And D-Day is a really bad day to start thinking about communications alternatives. You’ll have plenty of other things to do.

We’re going to make this fun today and provide all the tools you’ll need to set up shop in Amazon’s EC2 Cloud. The good news is that EC2 is almost free for your first year so getting started isn’t going to be a financial burden. Once you have everything built, you can turn it off and hope you never have to use it. On the other hand, it’s dirt cheap for an entire year so enjoy yourself and learn why VoIP communications can revolutionize your business at a fraction of the cost of a proprietary communications system. For our Asterisk aficionados that have already discovered the beauty of free VoIP communications, we’ve got some additional goodies today, Incredible Backup and Incredible Restore, that will let you quickly move your communications platform back and forth between EC2 and a local server or virtual machine effortlessly.

For those just getting started, the real beauty of VoIP communications is that, once your server platform is operational, you can bring up communications services for your employees without any hardware investment. A notebook computer and a free SIP softphone will let you make and receive calls through your EC2 communications system. By adding trunks from Google Voice or any SIP service provider, you complete the communications circle to connect to any phone in the world. We do this for a living so, if your business needs some hand-holding to get started, drop us a note. We like to travel.

The Choice is Yours: PIAF-Purple with Asterisk 1.8 or PIAF-Green with Asterisk 11

Getting Started. For your communications platform, we’ve built two new versions of PBX in a Flash™ for Amazon EC2: PIAF-Purple and PIAF-Green. You can’t beat the price. Both are free! These two builds are based upon the two long-term support (LTS) releases of Asterisk: 1.8 and 11. In our testing, both are rock solid and production-ready. If tried and true is your cup of tea, then PIAF-Purple with Asterisk 1.8 and FreePBX 2.10 is your baby. If you want to get a jump on the future, then PIAF-Green with Asterisk 11 and FreePBX 2.11 is worth a careful look. But, to use either one, you first need to get set up with an Amazon EC2 account. So head over to Amazon and click on Sign Up Now. A word to the wise here. You don’t want the bad guys breaking into your account unless you have an unlimited budget. There are lots of non-free Amazon EC2 services that could max out your credit card quickly. So, in addition to signing up for your Amazon account, also activate Multi-Factor Authentication. It’s your bank account!

Once your account is activated, sign in to the Amazon Management Console. After entering both your passwords, the AWS Management Console will appear. Click on EC2 to bring up the EC2 Dashboard (shown above). This is home base in EC2. The Launch Instance button is used to start a new virtual machine. We’ll walk you through that process in a minute. In the left margin are the functions you’ll be using most often. Instances displays your existing virtual machines, both running and stopped. Volumes are the virtual hard disks associated with your virtual machines or instances in Amazon-speak. A volume gets created as part of the VM launching process. When you delete instances, it’s important to also delete the associated volume, or you get billed for it separately. Elastic IPs lets you assign an IP address to an Instance using Amazon’s DHCP servers. You access your virtual machines using SSH and, without an IP address, you can’t gain access. For SSH security, EC2 uses Key Pairs. As part of launching a new virtual machine, we’ll walk you through creating one. Amazon EC2 also has its own firewalls called Security Groups. Basically, all services are blocked until you open them up. We’ll also walk you through that process as well. Once you’ve created your Key Pair and Security Group, you can use them with multiple instances. Now you’re an expert so let’s Launch a New Instance.

Creating a New Virtual Machine. Click on the blue Launch Instance button in the EC2 Dashboard to begin. Choose Classic Wizard. You build a new instance by starting with one that someone else has already built. Be careful here. There are literally thousands to choose from and, unless you know the creator, use Name Brand, trusted instances only. Anybody can hide anything in an instance that they’ve made publicly available. Think of your worst Trojan Horse horror story, and there’s probably a public Amazon instance to match it. For our purposes, the magic number you need to know is 399149154715. That’s our Amazon EC2 account number, and it means any instances prefixed with that number or our mugshot were created by us. So click on the Cloud Market and search for PIAF. In about a minute, both PIAF2 AMIs will appear. Pick your favorite but be sure the file name displays our smiling face. Then click Select. For the Instance Type, make sure T1 Micro is chosen. That’s the only free option during your first year. Leave the Availability Zone at No Preference and Number of Instances set to 1. Click Continue. In Advanced Instance Options, accept all of the defaults and click Continue. For Storage Device Configuration, accept the defaults by clicking Continue. Next, you’ll be prompted to add Tags to your Instance. This is a short-hand description to help you distinguish one instance from another. For the Name Value, enter something like PIAF-Purple-64 or PIAF-Green-64 and click Continue. Next, you’ll be prompted to create a Key Pair to use with the instance. If you don’t already have one, click Create New Key Pair and Continue. Once the key pair is created, the .pem file will be downloaded to your desktop computer. Change the permissions on the .pem file to what SSH requires: chmod 700 mykey.pem. You’ll need this key file to log into your instance with SSH so move it to a safe place. Next, you’ll create or use an existing Security Group. This sets up the firewall rules to use with your instance. For PBX in a Flash, you’ll need at least the following Inbound Rules in your Security Group: TCP 22 (SSH), TCP 80 (Web), TCP 1723 (for PPTP VPN only), and TCP 9001 (for WebMin access). For VoIP services, you’ll need UDP 5060 (SIP), UDP 10000-20000 (RTP), UDP 4569 (IAX), and UDP 69 (TFTP, if desired). EC2 lets you lock down Security Group entries to individual IP addresses. We strongly recommend this for SSH, Web, SIP, IAX, and TFTP services. If you need access from multiple IP addresses, just add additional Security Group rules for each address and service. Finally, you’ll be shown a summary of all your selections. If everything looks OK, click Launch to start the instance. While it’s starting up, click Elastic IPs from the left column of the EC2 Dashboard. Choose Allocate New Address and then Associate Address to connect it with the instance that just launched. Write down the IP address. You’ll need it for SSH access. Finally, click Instances and wait for your virtual machine to come on line with a green check mark.

Your First Login. Now you can log into your EC2 instance via SSH using your key file and the IP address associated with the instance: ssh -i mykey.pem -v ec2-user@54.235.12.34. If you’re using a Windows machine with Putty, use PuttyGen.exe to convert your .pem key into something Putty can understand before attempting to log in. Once you’re logged in, you need to immediately change all the default passwords:

  • sudo passwd (to change your ec2-user password)
  • sudo passwd root (to change your root password)
  • su root (to switch to the root account with your new password)
  • passwd-master (to change your FreePBX and web passwords)
  • cd /root (to switch to the /root directory)

Keep in mind that PBX in a Flash is a little different than a standard Linux install. It has been designed for use as the root user only. So, whenever you log into a PIAF instance in EC2, always execute the following command: su root && cd /root. Most Linux and PBX in a Flash utilities will not work properly if you attempt to execute them as the ec2-user! For web access and management of your server, point your browser to the IP address of your EC2 instance. If you’re new to PBX in a Flash, stop here and read the PBX in a Flash 2.0.6.3 Quick Start Guide. It’ll tell you everything you need to know to get started with PBX in a Flash.

Installing Incredible PBX. We’ve got a few more surprises for you today. First, there are new, GPL2-licensed releases of Incredible PBX: version 10 for FreePBX 2.10 and version 11 for FreePBX 2.11. If you’re new to all of this, Incredible PBX provides some additional layers of security for your server while also giving you dozens of turnkey Asterisk applications including text-to-speech, speech-to-text, SMS messaging, news, weather, stocks, and tide reports, and much more. You can read the Incredible PBX tutorial here. To install Incredible PBX while logged into your EC2 instance as root, issue the following commands and plug in your passwd-master password when prompted. If you’re using the PIAF-Green AMI, replace incrediblepbx10 with incrediblepbx11 below.

cd /root
wget http://incrediblepbx.com/incrediblepbx10.gz
gunzip incrediblepbx10.gz
chmod +x incrediblepbx10
./incrediblepbx10

Installing Incredible Fax. Yes, there’s more. Incredible Fax also works just fine on the EC2 platform. If you want the added convenience of having your Incredible PBX double as a free fax machine, run install-incredfax2 after the Incredible PBX 10 install completes. For Incredible PBX 11, run /root/incrediblefax11.sh. Plug in your email address for delivery of incoming faxes and enter your home area code when prompted. For every other prompt, just press the Enter key. If you’d like to also add the optional OCR utility, just choose it when prompted. For complete documentation, see this Nerd Vittles article. Don’t forget that a REBOOT OF YOUR SERVER is required when the install is finished, or faxing won’t work! Then log in to AvantFax through the PBX in a Flash GUI using maint:password. Be sure to change your password!

Also be sure to set up a second, dedicated Google Voice number if you want support for inbound faxing. Once the Google Voice credentials are configured in FreePBX for the additional Google Voice line, simply add an Inbound Route for this DID to point to the fax destination. Just plug in your 10-digit Google Voice number and other entries shown in the form below. Save your setup and reload FreePBX. Done!

Introducing Incredible Backup and Restore. Last, but not least, we have new GPL2-licensed backup and restore utilities to simplify the task of moving PBX in a Flash setups between Amazon EC2 and other standalone or virtual machine platforms. To complement these new utilities, we’ve also released a new 64-bit PIAF-Purple Virtual Machine image for VirtualBox. PIAF-Purple-64.ova is a free download from SourceForge and will run under VirtualBox on any Windows, Mac, Linux, or Solaris desktop computer. Our VirtualBox tutorial is available here. You also have the option of downloading the current 64-bit PIAF-20631 ISO from SourceForge and building your own server or virtual machine. All three platforms (Amazon EC2 AMI, VirtualBox OVA, or PIAF 64-bit ISO) are 100% compatible with Incredible PBX, Incredible Fax, and the new Incredible Backup. Once you have matching platforms, you can backup your PIAF or Incredible PBX setup on one platform and then restore it to a different platform by simply copying the backup image to the new platform and running Incredible Restore. The entire procedure takes only a couple of minutes.

To install the backup and restore utilities on either of the platforms, simply issue the following commands:

cd /usr/local/sbin
wget http://incrediblepbx.com/incrediblebackup10.tar.gz
tar zxvf incrediblebackup10.tar.gz
rm incrediblebackup10.tar.gz

Because Incredible Backup shuts down Asterisk, MySQL, and Apache, do NOT run this when folks are using your PBX! To make a backup, log into your server as root and type: incrediblebackup.

The restore procedure essentially erases ALL of your existing FreePBX, Asterisk, TFTP, and web data. To restore a backup, copy the backup file to be restored to /tmp on the new server. Make sure the new server has Asterisk, FreePBX, and Incredible PBX versions that match what’s shown in the backup filename. There is NO error checking presently. To restore, log into your server as root, write down the filename of the backup file, and type: incrediblerestore /tmp/filename.tar.gz. If this is a new server and you’re still using your old one as well, then remove the DUNDI secret and secretexpiry entries from the Asterisk DB and restart Asterisk once the restore is completed:

asterisk -rx "database del dundi secret"
asterisk -rx "database del dundi secretexpiry"
amportal restart

For additional usage instructions and tips, see this thread on the PIAF Forum. Enjoy!

The 5-Minute PBX: It’s Incredible PBX 11 Virtual Machine for VirtualBox

In our last article, we introduced the PBX in a Flash Virtual Machine for Oracle’s VirtualBox. To commemorate the end of the world today, we wanted to go out with a bang. So we’re pleased to introduce Incredible PBX 11 Virtual Machine. As with the PIAF-Green Virtual Machine, this new appliance features CentOS 6.3, Asterisk® 11, and FreePBX® 2.11 beta. In addition, it includes Incredible Fax with HylaFax and AvantFax, SMS speech-to-text messaging as well as SMS message blasting with Google Voice, and several dozen turnkey Asterisk applications including a speech-to-text phonebook dialer, text-to-speech news, weather, tide, and stock reports, a conference bridge for MeetMe conferencing, NeoRouter and PPTP VPN support, SAMBA for Windows Networking, ODBC database integration, Telephone Reminders and Hotel-Style Wakeup Calls, CallerID Superfecta, PBX End Point Manager, and Wolfram Alpha to name but a few. With the addition of free Google Voice accounts, you still get free voice and fax calling in 2013 throughout the United States and Canada. And, yes, Incredible PBX 11 still installs and is ready to go in under 5 minutes on any Windows, Mac, Linux, or Solaris desktop.

The Ultimate VoIP Appliance: Incredible PBX 11 Virtual Machine for VirtualBox

We broke new ground in the virtual machine development arena last week with the introduction of the PIAF Virtual Machine. Today we take it to the next plateau with a turnkey VoIP appliance that can be deployed and functional in less time than it takes you to shave. Today’s Incredible PBX Virtual Machine still gives you everything a bare metal install from source code would have provided. And, most importantly, the components are truly portable. They can be copied to a 4GB flash drive1 for the price of a good hamburger and installed from there onto any type of machine that happens to be in front of you. Five minutes later, you have a fully functional Asterisk server with FreePBX and exactly the same feature set and source code that you would have had installing Incredible PBX onto a dedicated server. Before you ask any questions, we urge you to try this VoIP appliance for yourself. The install process is as easy as 1-2-3:

  1. Download and install VirtualBox onto a Desktop Machine of your choice
  2. Download and double-click on Incredible PBX 11 Virtual Machine to import it into VirtualBox
  3. Select the Incredible PBX 11 Virtual Machine in VirtualBox Manager Window and click the Start button

Introducing Oracle VM VirtualBox

Here’s a quick review if you missed our last article. VirtualBox®, Oracle’s virtual machine platform inherited from Sun, is really something. 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 is to download one or more of the VirtualBox installers from VirtualBox.org or Oracle.com. As mentioned, our recommendation is to put all of the 100MB installers on a 4GB thumb drive. 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. Accept all of the default settings, and you’ll be good to go. For details, here’s a link to Oracle’s VM VirtualBox User Manual.

To get Incredible PBX VM installed on your desktop is quick and easy. Because the image tips the scales at over 2GB and due to the 2GB file size limit on many systems, we’ve chosen to split this download into two pieces. You need both of them. Just download them onto any flavor desktop from SourceForge. Once you’ve downloaded the two files, reassemble them into a single file known as an Open Virtualization Appliance (.ova). Then verify the checksums for the reassembled file to be sure everything is in its proper place. Finally, double-click on the .ova file which will initiate the import process into VirtualBox.

So let’s begin by downloading the two halves from SourceForge: INCREDIBLEPBX11aa and INCREDIBLEPBX11ab.

The reassembly procedure depends upon your desktop operating system. For Windows PCs, you’ll need to drop down to the Command Prompt, change to the directory in which you downloaded the two files, and type the following command:
 
copy /b INCREDIBLEPBX11aa + INCREDIBLEPBX11ab IncrediblePBX11.ova

To check the MD5/SHA1 checksums in Windows, download and run Microsoft’s File Checksum Integrity Verifier.

For Mac or Linux desktops, open a Terminal window, change to the directory in which you downloaded the two files, and type the following commands:
 
cat INCREDIBLEPBX11a{a..b} > IncrediblePBX11.ova
md5 IncrediblePBX11.ova (use md5sum for Linux)
openssl sha1 IncrediblePBX11.ova

The MD5 checksum for IncrediblePBX11.ova is b17655785ef00381ffd70899a19375f9. The SHA1 checksum is 86ccd31d64d3b51e10a8e7429548be6ce15ecd9b. If you have a match, proceed. Otherwise, rinse and repeat.

Importing Incredible PBX 11 Virtual Machine into VirtualBox

You only perform the import step one time. Once imported into VirtualBox, Incredible PBX is ready to use. There’s no further installation required, just like an OpenVZ template… only better. Double-click on the .ova file you downloaded to begin the procedure and load VirtualBox. When prompted, be sure to check the Reinitialize the Mac address of all network cards box. Read and accept the license agreement. Then click the Import button. Once the import is finished, you’ll see a new IncrediblePBX11 virtual machine in your VM List on the VirtualBox Manager Window. You need to make a couple of one-time adjustments to the IncrediblePBX11 Virtual Machine configuration to account for differences in sound and network cards on different host machines.

Click on IncrediblePBX11 Virtual Machine in the VM List. Then click Settings -> Audio and check the Enable Audio option and choose your sound card. Save your setup by clicking the OK button. Next click Settings -> Network. 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 to save your setup. Finally, click Settings -> System, uncheck Hardware clock in UTC time, and click OK. That’s all the configuration that is necessary for Incredible PBX Virtual Machine. If you blinked, you probably missed it.

Running Incredible PBX Virtual Machine in VirtualBox

Once you’ve imported and configured Incredible PBX Virtual Machine, you’re ready to go. Highlight the appliance in the VM List on the VirtualBox Manager Window and click the Start button. The boot procedure with CentOS 6.3 will begin just as if you had installed PBX in a Flash and Incredible PBX on a standalone machine. You’ll see a couple of dialogue boxes pop up that explain the keystrokes to move back and forth between your host operating system desktop and Incredible PBX.

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. For other operating systems, read the dialogue boxes for instructions on moving around. Always shut down Incredible PBX gracefully! Click in the VM window with your mouse, log in as root, and type: shutdown -h now. Or, from the VirtualBox Manager Window, Ctl-Click on the IncrediblePBX11 VM and choose Close -> ACPI Shutdown.

Always run Incredible PBX VM behind a hardware-based firewall with no Internet port exposure!

Linux CLI Setup. To begin, position your mouse over the VM window and left-click. Once the virtual machine has booted, log in as root with password as the password. Change your root password immediately by typing passwd at the command prompt. Now set up a secure maint password for FreePBX as well. Type passwd-master. If you’re not in the Eastern U.S. time zone, then you’ll want to adjust your timezone setting so that reminders and other time-sensitive events happen at the correct time. Issue the following command to pick your time zone: /root/timezone-setup. If you plan to use Incredible Fax to send and receive faxes, set an email address for delivery of incoming faxes: /root/incrediblefax-setup. To use SMS messaging in Incredible PBX, you’ll need a Google Voice account which is covered below. Once you have your credentials, edit extensions_custom.conf in /etc/asterisk and insert your username and password in the 767 extension. To use SAMBA for Windows networking, replace the Interfaces IP address in /etc/samba/smb.conf with your actual IP address. Next, run smbpasswd and assign a password for root access to your server. Then restart SAMBA: service smb restart.

FreePBX Setup. Use a browser to log into your Incredible PBX server by pointing to the IP address of the virtual machine displayed in the status window of the CLI. Click on the User button to display the Admin choices in the Main PIAF Menu. Click on the FreePBX Admin option to load the FreePBX GUI. You will be prompted for a username and password. For the username, use maint. For the password, use whatever password you set up with passwd-master above.

You’ll want to keep FreePBX up to date. The easiest way is to configure FreePBX for email notifications when there are updates. In the FreePBX GUI, choose Admin -> Module Admin -> Upgrade Notifications and plug in your email address. Updates are installed in this same window. Click Check Online -> Upgrade All -> Process and Confirm. Scroll to the bottom of the Status window and click Return. Then click Apply Config. Now you try it.

GOOGLE VOICE ALERT: For old-timers that used the previous Google Voice module in FreePBX 2.x, it’s a little different in FreePBX 2.11. It now is called Google Voice (Motif), and you’ll find it under the Connectivity tab instead of the Other tab. More importantly, the form has changed. Do NOT check all 3 checkboxes as you did previously, or your incoming calls won’t be answered. Leave last checkbox “Send Unanswered to GoogleVoice Voicemail” UNCHECKED!!

Incredible PBX supports SIP, IAX, and Google Voice trunks to handle your outbound and incoming calls. The easiest way to get started it to set up a couple of Google Voice trunks, one for voice calls and one for faxing. These trunks must be dedicated for exclusive use with Incredible PBX. If you’re logged into these Google Voice accounts elsewhere, Incredible PBX won’t receive incoming calls. Read our Incredible PBX Quick Start Guide for the procedure to register for new Google Voice accounts. Once you have your credentials and phone numbers, choose Connectivity -> Google Voice in FreePBX to set up the accounts in FreePBX. For each trunk, you also need to set up an Inbound Route to tell FreePBX how to route the incoming calls. For your Fax trunk, here’s the drill. Choose Connectivity -> Inbound Routes. Insert your 10-digit Google Voice number in the DID Number field. Check Enable CID Superfecta and, for Set Destination, choose Custom Destinations -> Fax (HylaFax). Click Submit and then click Apply Config.

Before your Google Voice trunks will work reliably, there are two final steps. First, restart Asterisk from the Linux CLI: amportal restart. Then, make at least one outbound call using each Google Voice trunk.

We’ve preconfigured SIP trunks for all of the major VoIP providers in Incredible PBX. All you have to do is sign up for a few accounts. This isn’t like the old Ma Bell days so take advantage of the redundancy that using multiple VoIP providers gives you. There’s a very special offer from one of the major sponsors of the PBX in a Flash and Nerd Vittles projects below. Take advantage of it and support our open source projects.

1-7-13 Security Alert: We’ve just released Incredible PBX 11.1.2 which includes Asterisk 11.1.2 and the latest FreePBX 2.11 beta. The Asterisk Dev Team announced a serious security vulnerability in Asterisk 1.8, 10, and 11 late last week. This update addresses that. You can read all about it in the readme file on SourceForge. If you still are using an earlier version of Incredible PBX 11, make certain that it is behind a hardware-based firewall with no Internet port exposure. And you should immediately patch your server or, better yet, switch to this new release.

Now read the latest Incredible PBX Quick Start Guide and begin your VoIP adventure. Then you’ll want to do some reading on VirtualBox. We’ve barely scratched the surface. Setting up Headless VMs that run in the background on any server is a breeze. From the command line, here’s an article to get you started. But you also can start Headless VMs from within the GUI by highlighting the VM and clicking Shift->Start. REMEMBER: Always shut down VMs gracefully: Close->ACPI Shutdown. You’ll find more great tips at virtualbox.org and GitHub.

One of the real beauties of VirtualBox is you don’t have to use a GUI at all. The entire process can be driven from the command line. Other than on a Mac, here is the procedure to import, configure, and run Incredible PBX 11 Virtual Machine:
 
VBoxManage import IncrediblePBX11.ova
VBoxManage modifyvm "IncrediblePBX11" --nic1 nat
VBoxManage modifyvm "IncrediblePBX11" --acpi on --nic1 bridged
VBoxHeadless --startvm "IncrediblePBX11" &
# Wait 1 minute for IncrediblePBX11 to load. Then decipher IP address like this:
VBoxManage guestproperty get "IncrediblePBX11" /VirtualBox/GuestInfo/Net/0/V4/IP
# Now you can use SSH to login to IncrediblePBX11 at the displayed IP address
# Shutdown the IncrediblePBX11 Virtual Machine with the following command:
VBoxManage controlvm "IncrediblePBX11" acpipowerbutton

On a Mac, everything works the same way except for deciphering the IP address. Download our findip script for that.

Have a very Merry Christmas!

The 5-Minute PBX: PIAF Virtual Machine for VirtualBox (Windows, Mac, or Linux)

For most of us, today marks the last time we’ll ever see the day, month, and year line up on the calendar in perfect harmony so Happy 12-12-12 to everyone. It’ll be 88+ years before it happens again. And the Mayans believe the world will be ending in 9 more days so there may be no need to worry about the 88 years anyway. Whatever happens, it seemed like an appropriate time to take stock of how we’re doing in the development of the Perfect PBX™. Such an assessment, of course, is in the eyes of the beholder. From our perspective, in addition to being feature-rich, it has to have three components: ease of installation, ease of use, and flexibility. The first two are self-explanatory but flexibility needs some explanation. Flexibility to us means a feature set that’s appealing not only to those just beginning the journey but also to those of us that need to make frequent changes and additions to the platform to keep it current or make it better. After all, that’s what open source is all about.

The real beauty of PBX in a Flash has not been that someone with sufficient expertise couldn’t assemble something just as good or even better. Watch the AstriCon presentations from this year if you have any doubts. The beauty of PIAF is it puts this technology down where the goats can get it. It provides a toolset that encourages further development by simplifying the learning curve for a broad cross-section of the VoIP community while not compromising functionality or flexibility. The source code for the major components is included in the build so you can customize and recompile Asterisk or load a new version of Asterisk or any additional Linux app in minutes without losing your existing setup.

As many of you know, we have literally hundreds of gurus on the PIAF Forum. That doesn’t mean any particular person or group knows everything. It’s merely a designation that a particular individual is an expert at something. The collective wisdom of the group is what makes PBX in a Flash as a project better because we’ve put in place a platform that experts from many different disciplines can build upon without needing to learn everything about everything. Simply stated, you can be a terrific chef without knowing how to build a stove!

Turning to Asterisk® 11 and FreePBX® 2.11, from everything we’re seeing, these new releases are shaping up to be a remarkable step forward both in terms of toolset and in the new mindset of the development community. That’s a good thing. For our part, we’ve wanted to get our latest preview release of PBX in a Flash with CentOS 6.3, Asterisk 11 and the new FreePBX 2.11 beta into as many hands as possible keeping in mind the objectives we outlined above.

The Ultimate VoIP Appliance: PIAF Virtual Machine for VirtualBox

Today brings us to a new plateau in the virtual machine development era. Thanks to the masterful work of Tom King on PBX in a Flash 2.0.6.3.1, we’re pleased to introduce a new product that can be installed in under 5 minutes and will run on any Windows PC, Mac, or Linux machine as well as Solaris. And, unlike the dedicated machine platforms and OpenVZ compromises of years past, today’s PIAF Virtual Machine gives you everything a bare metal install from source code would have provided. Most importantly, the components are truly portable. They can be copied to a 4GB flash drive1 for the price of a good hamburger and installed from there onto any type of machine that happens to be in front of you. Five minutes later, you have a fully functional Asterisk server with FreePBX and exactly the same feature set and source code that you would have had doing a bare metal PIAF install to a dedicated server. And we’ve built both a production-ready PIAF-Purple VM with Asterisk 1.8 and FreePBX 2.10 as well as a Pioneer edition PIAF-Green VM with Asterisk 11 and FreePBX 2.11 beta. The choice is yours. No Internet access required to perform the install. Sound too good to be true? Keep reading or, better yet, try the PIAF appliance for yourself. The install process is simple:

  1. Download and install VirtualBox onto a Desktop Machine of your choice
  2. Download and double-click on the PIAF Virtual Machine to import it into VirtualBox
  3. Select the PIAF Virtual Machine in VirtualBox Manager Window and click the Start button

Introducing Oracle VM VirtualBox

We’re late to the party, but Virtual Box®, Oracle’s virtual machine platform inherited from Sun, is really something. 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 is to download one or more of the VirtualBox installers from VirtualBox.org or Oracle.com. As mentioned, our recommendation is to put all of the 100MB installers on a 4GB thumb drive. 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. 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.

Introducing the PIAF Virtual Machine

We’ll walk you through installing the PIAF-Green Virtual Machine. It’s basically the same procedure with PIAF-Purple except you get to skip the reassembly step since the PIAF-Purple.ova image is only 1.3GB.

The PIAF-Green Virtual Machine tips the scales at over 2GB. Because of the 2GB file size limit on many systems, we’ve chosen to split this download into two pieces. You need both of them. Just download them onto any flavor desktop from SourceForge. Once you’ve downloaded the two files, we need to reassemble them into a single file known as an Open Virtualization Appliance (.ova). Then verify the checksums for the reassembled file to be sure everything is in its proper place. Finally, we’ll double-click on the .ova file which will initiate the import process into VirtualBox.

So let’s begin by downloading the two halves of PIAF-Green from SourceForge: PIAFGREENaa and PIAFGREENab. If you’d prefer production-ready code, just download PIAF-Purple.ova and skip the reassembly step. There’s also a new surprise offering that’s covered in the comments to this article. :-)

The reassembly procedure depends upon your desktop operating system. For Windows PCs, you’ll need to drop down to the Command Prompt, change to the directory in which you downloaded the two files, and type the following command:
 
copy /b PIAFGREENaa + PIAFGREENab PIAF-Green.ova

To check the MD5/SHA1 checksums in Windows, download and run Microsoft’s File Checksum Integrity Verifier.

For Mac or Linux desktops, open a Terminal window, change to the directory in which you downloaded the two files, and type the following commands:
 
cat PIAFGREENa{a..b} > PIAF-Green.ova
md5 PIAF-Green.ova (use md5sum for Linux)
openssl sha1 PIAF-Green.ova

The correct MD5 checksum for PIAF-Green ( PIAF-Green.ova) is a86a018466c7045372e51100cddd42ea. For PIAF-Purple.ova, it’s 664b1afe75c3b1877029531b0fe28063. The correct SHA1 checksum for PIAF-Green is d883c5e137ac19ecb45c1e6f127180b78a9cd0af. For PIAF-Purple, it’s 15f94352745ca989fd9939d9a8ee8b765fc8388c. If you have a match, proceed. Otherwise, rinse and repeat.

Importing the PIAF Virtual Machine into VirtualBox

You only perform the import step one time. Once imported into VirtualBox, PBX in a Flash is ready to use. There’s no further installation required, just like an OpenVZ template… only better. Double-click on the .ova file you downloaded to begin the procedure and load VirtualBox. When prompted, be sure to check the Reinitialize the Mac address of all network cards box and then click the Import button. Once the import is finished, you’ll see a new PIAF virtual machine in your VM List on the VirtualBox Manager Window. Regardless of flavor, you’ll need to make a couple of one-time adjustments to the PIAF Virtual Machine configuration to account for differences in sound and network cards on different host machines.

Click on the PIAF Virtual Machine in the VM List. Then click Settings -> Audio and check the Enable Audio option and choose your sound card. Save your setup by clicking the OK button. Next click Settings -> Network. 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. Finally, click Settings -> System, uncheck Hardware clock in UTC time, and click OK. That’s all the configuration that is necessary for your PIAF Virtual Machine. The rest is automagic.

Running the PIAF Virtual Machine in VirtualBox

Once you’ve imported and configured the PIAF Virtual Machine, you’re ready to go. Highlight PIAF Virtual Machine in the VM List on the VirtualBox Manager Window and click the Start button. The PIAF boot procedure with CentOS 6.3 will begin just as if you had installed PBX in a Flash on a standalone machine. You’ll 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 PIAF VM.

Here’s what you need to know. To work in the PIAF 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. For other operating systems, read the dialogue boxes for instructions on moving around. Always shut down PIAF gracefully! Click in the VM window with your mouse, log in as root, and type: shutdown -h now.

Run the PIAF Virtual Machine behind a hardware-based firewall with no Internet port exposure!

To begin, position your mouse over the VM window and left-click. Once the PIAF VM has booted, log in as root with password as the password. Change your root password immediately by typing passwd at the command prompt. Now set up a secure maint password for FreePBX as well. Type passwd-master. If you’re not in the Eastern U.S. time zone, then you’ll want to adjust your timezone setting so that reminders and other time-sensitive events happen at the correct time. While logged into your server as root, issue these commands to download and run the timezone-setup script:

cd /root
wget http://pbxinaflash.com/timezone-setup.tar.gz
tar zxvf timezone-setup.tar.gz
./timezone-setup

Next, use a browser to log into your PIAF server by pointing to the IP address of the PIAF VM that’s displayed in the status window of the CLI. Click on the User button to display the Admin choices in the main PIAF Menu. Click on the FreePBX option to load the FreePBX GUI. You will be prompted for an Apache username and password. For the username, use maint. For the password, use whatever password you set up with passwd-master.

Now read the latest PIAF Quick Start Guide and begin your VoIP adventure. Then you’ll want to do some reading on VirtualBox. We’ve barely scratched the surface. Setting up Headless VMs that run in the background on any server is a breeze. From the command line, here’s an article to get you started. But you also can start Headless VMs from within the GUI by highlighting the VM and clicking Shift->Start. Always shut down VMs gracefully: Close->ACPI Shutdown.

VBoxHeadless --startvm "PIAF-Purple" &
# Wait 1 minute for PIAF-Purple to load. Then decipher IP address like this:
VBoxManage guestproperty get "PIAF-Purple" /VirtualBox/GuestInfo/Net/0/V4/IP
# Now you can use SSH to login to PIAF-Purple at the displayed IP address
# Shutdown the PIAF-Purple Virtual Machine with the following command:
VBoxManage controlvm "PIAF-Purple" acpipowerbutton

On a Mac, everything works the same way except for deciphering the IP address. Download our findip script for that.

Enjoy!
