The new Incredible PBX 13.2 ISO can be burned to either a DVD-ROM or a 1GB or larger USB flash drive using a Mac, a Windows PC, or almost any Linux machine. And, unlike the FreePBX Distro, you’re more than welcome to share our code and the ISO with all of your friends and business associates. In fact, next week we’re releasing the entire Incredible PBX build platform for those of you that want to roll your own ISO. Share your enhancements and tweaks or make a customized ISO for just your company and pass it around. We’d be delighted. And our previous tutorial will even show you how to set up and maintain your own Cloud Repository for Incredible PBX. FREEDOM: THAT’S WHAT OPEN SOURCE IS ALL ABOUT!

NEWS FLASH: Check out the new Incredible PBX 13-13 ISO. Complete tutorial available here.

Overview. The Incredible PBX installation process couldn’t be easier. Download IncrediblePBX13.2.iso from SourceForge. Burn the ISO to a DVD-ROM or USB thumb drive. Four different methods are outlined below. Need some great hardware for under $200? Read our tutorial. Or, if you have an old PC lying around, that’ll work, too. Boot up the dedicated machine on which you want to install Incredible PBX. Choose whether you prefer the Incredible PBX Whole Enchilada with 30+ applications for Asterisk or the Lean & Mean version which has its own separate tutorial here. Press the ENTER key. Choose your time zone, create a really secure root password, and have a coffee break. When Scientific Linux 6.7 has been installed, your server will reboot. Accept the Incredible PBX license agreement and press the ENTER key. Go to lunch and, when you return, you should be good to go. Finish reading this tutorial to add the finishing touches and secure your server. Then read the Incredible PBX Application Users Guide to learn all about the three dozen FREE applications for Asterisk® that are included in the build. DONE!

Let us take a moment to explain the Incredible PBX installation process using this ISO. We don’t hide stuff in our ISO or play games with your security. We don’t give ourselves or our application any secret permissions. There are just two steps to an Incredible PBX ISO install. When the install begins, it loads pure Scientific Linux onto your server,¹ not some homegrown concoction using proprietary repositories. Your server then reboots. After restarting, the very latest copy of the Incredible PBX 13-12 installer is downloaded and run (see the actual source code of the script below). You’ll find the source code for the Incredible PBX installer in your /root directory after the install is completed: IncrediblePBX13-12R.sh. You’ll also find some other helpful scripts in /root including the optional (free) Incredible Fax installer. If you ever have a question about what was installed on your server, feel free to examine the source code of our installers or post a note on the PIAF Forum. It’s unencrypted GPL2 code. You’re free to use it, enhance it, and share it. Try that with Sangoma. It’s your choice!

Downloading the Incredible PBX 13.2 ISO. On the machine you’ll be using to create your installation media, download IncrediblePBX13.2.iso from SourceForge. Update: The 11/29/2015 version of the ISO had a bug that prevented proper installation of Incredible PBX Full Enchilada. The 12/01/2015 release fixed the problem.

Burning a DVD-ROM from the ISO. If your server platform doesn’t have USB support, then burn the ISO to a DVD using a Mac or Windows machine.

Creating a USB Flash Drive Installer. If your server platform has USB ports, you have three ways to move the Incredible PBX 13.2 ISO to a 1GB or larger flash drive. You can use a Windows PC, a Mac, or a Linux machine to create the USB thumb drive installer.

Creating a USB Flash Drive Installer with a Windows PC. In order to create a USB thumb drive using an ISO image, you’ll first need to install Rufus. It’s free. Once you’ve installed it, insert a blank USB thumb drive and run Rufus. Make your settings look like what’s shown above. Be very careful in choosing your Device. You don’t want to accidentally erase the wrong drive on your Windows machine. The correct choice is the USB thumb drive you just inserted. Don’t guess!! Step 2 is choosing the IncrediblePBX13.2.iso file that you downloaded from SourceForge. Step 3 is clicking Start. The ISOHybrid Window will be presented. Step 4 is changing the default setting to "Write in DD image mode." Step 5 is pressing OK. In a few minutes, your ISO image transfer to the USB flash drive will be finished. Give it 15 seconds just to be safe. Then remove the USB thumb drive and you’re ready to begin the install on your dedicated Incredible PBX server.

Creating a USB Flash Drive Installer with a Mac. To create a USB thumb drive using an ISO image on a Mac, first insert the USB thumb drive and partition it with a single MS-DOS partition using Disk Utility. Next, open a Terminal window and issue the command: diskutil list. Review the device names and find the one that matches the size of your thumb drive. It will be something like /dev/disk9. Again, be careful. You don’t want to accidentally erase the wrong drive on your Mac! Next, change to the directory into which you downloaded IncrediblePBX13.2.iso, e.g. cd Desktop. Now issue the following commands substituting the actual device name for /dev/disk9 below:

diskutil unmountDisk /dev/disk9
sudo dd if=IncrediblePBX13.2.iso bs=1m of=/dev/disk9
sudo sync
diskutil eject /dev/disk9

When the install completes, remove the USB thumb drive and you’re ready to begin the install on your dedicated Incredible PBX server. NOTE: There will be no feedback during the dd step above. It can take 15 minutes or more depending upon the horsepower of your Mac. Be patient!

Creating a USB Flash Drive Installer on a Linux machine. To create a USB thumb drive using an ISO image on a Linux machine, first log into your server as root. Insert a blank USB thumb drive. From the CLI, decipher the device name of your thumb drive: fdisk -l. The device name will be something like /dev/sdb. Be careful. You don’t want to accidentally erase the wrong drive on your Linux server! Change to the directory into which you downloaded IncrediblePBX13.2.iso, e.g. cd /root. To transfer the ISO to your thumb drive, issue the following commands replacing /dev/sdb with the actual device name for your thumb drive in lines 1 and 3 below:

dd if=IncrediblePBX13.2.iso bs=4M of=/dev/sdb
sync
udisks --detach /dev/sdb

When the install completes, remove the USB thumb drive and you’re ready to begin the install on your dedicated Incredible PBX server. NOTE: There will be no feedback during the dd step above. It can take 5 to 15 minutes depending upon the horsepower of your Linux machine.

Kicking Off the Incredible PBX 13 Install. Now we’re ready to install Incredible PBX 13 on your dedicated server platform. Simply insert the DVD-ROM or USB thumb drive in your server-to-be and boot. During the POST boot process, press the function key that displays a Boot Device Menu and choose your DVD-ROM drive or USB device. When the Incredible PBX 13 installation menu displays, choose Basic Install and press ENTER. Choose your time zone, create a really secure root password, and have a coffee break. When Scientific Linux 6.7 has been installed, your server will reboot. Accept the Incredible PBX license agreement and press the ENTER key. Go to lunch and, when you return, you should be good to go. When the installation finishes, reboot your server and log in as root to apply the last minute updates for Incredible PBX.

To complete the install, perform the following from the Linux CLI while logged in as root:

• Change your root password if it’s insecure: passwd
• Set your Incredible GUI admin password: /root/admin-pw-change
• Set your web apps admin password: htpasswd /etc/pbx/wwwpasswd admin
• 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
• *** THE REMAINING FEATURES ARE OPTIONAL ADDITIONS ***
• Login to your NeoRouter VPN server: /root/nrclientcmd
• Download latest Incredible Fax installer: http://nerd.bz/2nSeHKs
• To enable free faxing: /root/incrediblefax11.sh
• Set admin password for AvantFax: /root/avantfax-pw-change
• To enable PPTP VPN: /root/pptp-install
• To enable Google Voice OAUTH authentication: http://nerd.bz/1JaO4ij (1b.)
• To remove GPL Module Signature Checking in GUI: http://nerd.bz/1fpwZJL
• To install FCC RoboCall BlackList: http://nerdvittles.com/?p=15412
• To upgrade Asterisk to current release²: /root/upgrade-asterisk-to-current
• To upgrade all FreePBX GPL Modules: /var/lib/asterisk/bin/module_admin upgradeall && rm -f /tmp/* && amportal a r

Most of your time initially configuring and managing your server will be spent using the web-based tools provided with Incredible PBX. Using any modern browser, go to the IP address of your server as shown in the status display above. This will bring up the Kennonsoft GUI that provides access to all of the web-based applications. Toggle between User and Admin apps by clicking on the blue tab in the lower left section of the display. This GUI also displays the latest security alerts and bug fixes from the PIAF RSS Feed. We recommend you check it at least once a week.

The other GUI to configure the FreePBX® GPL modules is accessed from the Admin menu in the Kennonsoft menus. Choose Incredible GUI Administration. The default username is admin and the password is what you set during the final installation steps above. Once the Incredible PBX GUI appears, edit extension 701 so you can figure out (or change) the randomized passwords that were set up for your 701 extension and voicemail account: Applications -> Extensions -> 701. If you’re behind a hardware-based firewall, verify the NAT setting is set to YES.

Now you’re ready to set up a telephone so that you can play with Incredible PBX. We recommend YateClient which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 701 extension on Incredible PBX. You’ll need the IP address of your server plus your extension 701 password. Choose Settings -> Accounts and click the New button. Fill in the blanks using the IP address of your server, 701 for your account name, and whatever password you created for the extension. Click OK.

Once you are registered to extension 701, close the Account window. Then click on YATE’s Telephony Tab and place some test calls to the numerous apps that are preconfigured on Incredible PBX. Dial a few of these to get started:

Now you’re ready to connect to the telephones in the rest of the world. If you live in the U.S., the easiest way (at least for now) is to set up a free Google Voice account. Google has threatened to shut this down but as this is written, it still works. Upgrading your server for OAUTH authentication is covered here. Start at step #1b. The safer long-term solution is to choose several SIP providers and set up redundant trunks for your incoming and outbound calls. The PIAF Forum includes dozens of recommendations to get you started.

If you want to use Google Voice, you’ll need a dedicated Google Voice account to support Incredible PBX. If you want to use the inbound fax capabilities of Incredible Fax, then you’ll need an additional Google Voice line that can be routed to the FAX custom destination using the GUI. The more obscure the username (with some embedded numbers), the better off you will be. This will keep folks from bombarding you with unsolicited Gtalk chat messages, and who knows what nefarious scheme will be discovered using Google messaging six months from now. So keep this account a secret!

We’ve tested this extensively using an existing Gmail account, and inbound calling is just not reliable. The reason seems to be that Google always chooses Gmail chat as the inbound call destination if there are multiple registrations from the same IP address. So, be reasonable. Do it our way! Set up a dedicated Gmail and Google Voice account, and use it exclusively with Incredible PBX. It’s free at least through 2013. Google Voice no longer is by invitation only so, if you’re in the U.S. or have a friend that is, head over to the Google Voice site and register.

You must choose a telephone number (aka DID) for your new account, or Google Voice calling will not work… in either direction. Google used to permit outbound Gtalk calls using a fake CallerID, but that obviously led to abuse so it’s over! You also have to tie your Google Voice account to at least one working phone number as part of the initial setup process. Your cellphone number will work just fine. Don’t skip this step either. Just enter the provided 2-digit confirmation code when you tell Google to place the test call to the phone number you entered. Once the number is registered, you can disable it if you’d like in Settings, Voice Setting, Phones. But…

IMPORTANT: Be sure to enable the Google Chat option as one of your phone destinations in Settings, Voice Setting, Phones. That’s the destination we need for The Incredible PBX to work its magic! Otherwise, all inbound and outbound calls will fail. If you don’t see this option, you may need to call up Gmail and enable Google Chat there first. Then go back to the Google Voice Settings.

While you’re still in Google Voice Settings, click on the Calls tab. Make sure your settings match these:

Click Save Changes once you adjust your settings. Under the Voicemail tab, plug in your email address so you get notified of new voicemails. Down the road, receipt of a Google Voice voicemail will be a big hint that something has come unglued on your PBX.

UPDATE: Google has improved things… again. You may not see the options documented above at all. Instead, you may be presented with the new Google Voice interface which does not include the Google Chat option. But fear not. At least for now there’s still a way to get there. After you have set up your new phone number, click on (1) Settings -> Phone Numbers and then click (2) Transfer (as shown below). That returned the old UI. Make sure the Google Chat option is selected and disable forwarding calls to default phone number.

One final word of caution is in order regardless of your choice of providers: Do NOT use special characters in any provider passwords, or nothing will work!

Now you’re ready to set up your Google Voice trunk in the GUI. After logging in with your browser, click the Connectivity tab and choose Google Voice/Motif. To Add a new Google Voice account, just fill out the form. Do NOT check the third box or incoming calls will never ring!

IMPORTANT LAST STEP: Google Voice will not work unless you restart Asterisk from the Linux command line at this juncture. Using SSH, log into your server as root and issue the following command: amportal restart.

If you have trouble getting Google Voice to work (especially if you have previously used your Google Voice account from a different IP address), try this Google Voice Reset Procedure. It usually fixes connectivity problems. If it still doesn’t work, enable Less Secure Apps using this Google tool.

You can avoid one-way audio on calls and touchtones that don’t work with these simple settings in the GUI: Settings -> Asterisk SIP Settings. Just plug in your public IP address and your private IP subnet. Then set ULAW as the only Audio Codec.

Incredible PBX for Scientific Linux joins our previous builds as our most secure turnkey PBX implementation. As configured, it is protected by both Fail2Ban and a hardened configuration of the IPtables Linux firewall. The latest release also includes Port Knocker for simple, secure access from any remote computer or smartphone. You can get up to speed on how the technology works by reading the Nerd Vittles tutorial. Your Port Knocker credentials are stored in /root/knock.FAQ together with activation instructions for your server and mobile devices. The NeoRouter VPN client also is included for rock-solid, secure connectivity to remote users. Read our previous tutorial for setup instructions. As configured, nobody can access your PBX without your credentials AND an IP address that is either on your private network or that matches the IP address of your server or the PC from which you installed Incredible PBX. You can whitelist additional IP addresses by running the command-line utility /root/add-ip. You can remove whitelisted IP addresses by running /root/del-acct. Incredible PBX is preconfigured to let you connect to many of the leading SIP hosting providers without additional firewall tweaking. We always recommend you also add an extra layer of protection by running your server behind a hardware-based firewall with no Internet port exposure, but that’s your call. And it’s your phone bill. 😉

The IPtables firewall is a complex piece of software. If you need assistance with configuring it, visit the PIAF Forum for some friendly assistance.

We’re pleased to introduce our latest backup and restore utilities for Incredible PBX. Running /root/incrediblebackup will create a backup image of your server in /tmp. This backup image then can be copied to any other medium desired for storage. To restore it to another Incredible PBX server, simply copy the image to a server running Asterisk 13 and the same version of the Incredible PBX GUI. Then run /root/incrediblerestore. Doesn’t get much simpler than that.

Every time you log into your server as root, Incredible PBX will ping the IncrediblePBX.com web site to determine whether one or more updates are available to bring your server up to current specs. We recommend you log in at least once a week just in case some new security vulnerability should come along. We originally had planned to make our fortune off update fees, but we changed our mind. So… contrary to the language in some of our builds, contributions to our projects are PURELY VOLUNTARY. You’ll get every update as it’s released whether you financially support our projects or not. Why haven’t we fixed the language? Good question. The short answer is it’s buried deep in the GUI image that would have to be regenerated from scratch. We’ll get to it one of these days. In the meantime, sleep soundly. No one will be breaking down your door for a donation.

We also encourage you to sign up for an account on the PIAF Forum and join the discussion. In addition to providing first-class, free support, we think you’ll enjoy the camaraderie.

Your next stop ought to be learning about the three dozen applications included in Incredible PBX. We’ve put together this tutorial to get you started. Enjoy!

Some Recent Nerd Vittles Articles of Interest…

1. If you’re wondering what packages are installed with Scientific Linux, come back next week and download the entire Incredible PBX ISO build environment. All of the packages installed on your server are included in the build platform itself. Feel free to add to them or change them to your heart’s content. We don’t have a million dollar staff. That’s why we depend upon folks like you to offer suggestions and enhancements. In short, we treat Incredible PBX like a real open source project. Come join the fun! [↩]
2. This is unnecessary when you first install Incredible PBX because it automatically installs the latest version of Asterisk 13. [↩]

We’ve spent much of 2015 developing a new GPL VoIP platform for virtually every Linux flavor in the universe with Incredible PBX installers for CentOS, Ubuntu, Debian, and Raspbian for the Raspberry Pi. Along the way we introduced the first turnkey aggregations for Asterisk® 13, an incredible new platform that’s been under development for several years. Until now, we’ve left the initial deployment of the operating system platform up to you. There were two principal reasons for shifting to this two-step install. First, there was the sale of CentOS to RedHat which set off red flags as to whether RedHat would now raise legal objections to bundling a superset of GPL applications with the base CentOS install, something which the original CentOS developers swore they would never do. Second, we didn’t want to get in the operating system business with maintenance of an independent repository to address security issues and to avoid legal issues from the RedHat folks.

But we heard from more than a few that the two-step process could be tedious especially for those that were new to Linux. Luckily, there’s another derivative of RHEL called Scientific Linux. As the name implies, it is used and was developed primarily to support the worldwide scientific community. Many have contributed to the Scientific Linux build over the years, but its principal sponsor is Fermi Lab which is managed by the Fermi Research Alliance LLC for the U.S. Department of Energy Office of Science. As a National Laboratory funded by the federal government, Fermi Lab’s work products including Scientific Linux constitute U.S. Government Works. As such, in addition to its GPL license, Scientific Linux can be used by others to create derivative works. That’s a long-winded explanation of why we’re now comfortable getting back into the ISO business and building an incredibly powerful unified communications system atop the Scientific Linux GNU platform. For those that have dealt with Asterisk aggregations over the past 10 years, this design is nothing particularly new. What is unique is the mix of features in the Incredible PBX aggregation. We begin with a preconfigured Asterisk 13 platform. Then we’ve added a large collection of FreePBX® GPL modules to create the web-based Incredible GUI for management of your server. Finally, we’ve integrated over three dozen applications for Asterisk as well as a preconfigured, functioning firewall to give you a rock-solid, secure UC VoIP platform with an unrivaled feature set for your home office or small business.

The installation procedure with the Incredible PBX 13 ISO couldn’t be easier. Start by downloading the 32-bit ISO from SourceForge to your desktop computer. The file name is IncrediblePBX13.iso. If you prefer a torrent, that’s available as well. The file name is IncrediblePBX13-12.2-SL67-ISO.torrent. After completing the download, if you’ll be using dedicated hardware for your platform, burn the ISO to a DVD using a Mac or Windows machine. Then boot your hardware from the device you just created. If you’re using a virtual machine such as VirtualBox, then designate the ISO as the VM boot device. Then start the virtual machine to begin the install.

When the installation begins, choose your time zone and create a very secure root password. After about 5 minutes, the Scientific Linux platform will be in place and your system will reboot. Agree to the Incredible PBX license agreement and press ENTER to complete the install. After one more reboot, you’ll be in business. Log in as root with your new password. After the Automatic Update Utility brings your system current, press ENTER after reviewing the status display for errors. To install Incredible Fax, issue this command and accept all the defaults by pressing ENTER: /root/incrediblefax11.sh
If you prefer secure OAUTH2 authentication for your Google Voice accounts, follow this tutorial beginning at step #1b.

UPDATE: Today’s build of Incredible PBX is now available in the RentPBX Cloud with your choice of Asterisk 11 or 13 in the following locales: Seattle, Los Angeles, Mountain View, Dallas, Chicago, Atlanta, Tampa, Miami, Ashburn/Washington D.C., New Jersey, Montreal, Toronto, Berlin, and Northern U.K. Use coupon code NOGOTCHAS for $15/month pricing.

To complete the install, perform the following from the Linux CLI while logged in as root:

• Change your root password if it’s insecure: passwd
• Set your FreePBX admin password: /root/admin-pw-change
• Set your web apps admin password: htpasswd /etc/pbx/wwwpasswd admin
• Set your admin password for AvantFax: /root/avantfax-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
• Login to your NeoRouter VPN server if desired: /root/nrclientcmd

One final word of caution is in order regardless of your choice of providers: Do NOT use special characters in any provider passwords, or nothing will work!

Now you’re ready to set up your Google Voice trunk in the GUI. After logging in with your browser, click the Connectivity tab and choose Google Voice/Motif. To Add a new Google Voice account, just fill out the form. Do NOT check the third box or incoming calls will never ring!

IMPORTANT LAST STEP: Google Voice will not work unless you restart Asterisk from the Linux command line at this juncture. Using SSH, log into your server as root and issue the following command: amportal restart.

If you have trouble getting Google Voice to work (especially if you have previously used your Google Voice account from a different IP address), try this Google Voice Reset Procedure. It usually fixes connectivity problems. If it still doesn’t work, enable Less Secure Apps using this Google tool.

You can avoid one-way audio on calls and touchtones that don’t work with these simple settings in the GUI: Settings -> Asterisk SIP Settings. Just plug in your public IP address and your private IP subnet. Then set ULAW as the only Audio Codec.

Incredible PBX for Scientific Linux joins our previous builds as our most secure turnkey PBX implementation. As configured, it is protected by both Fail2Ban and a hardened configuration of the IPtables Linux firewall. The latest release also includes Port Knocker for simple, secure access from any remote computer or smartphone. You can get up to speed on how the technology works by reading the Nerd Vittles tutorial. Your Port Knocker credentials are stored in /root/knock.FAQ together with activation instructions for your server and mobile devices. The NeoRouter VPN client also is included for rock-solid, secure connectivity to remote users. Read our previous tutorial for setup instructions. As configured, nobody can access your PBX without your credentials AND an IP address that is either on your private network or that matches the IP address of your server or the PC from which you installed Incredible PBX. You can whitelist additional IP addresses by running the command-line utility /root/add-ip. You can remove whitelisted IP addresses by running /root/del-acct. Incredible PBX is preconfigured to let you connect to many of the leading SIP hosting providers without additional firewall tweaking. We always recommend you also add an extra layer of protection by running your server behind a hardware-based firewall with no Internet port exposure, but that’s your call. And it’s your phone bill. 😉

The IPtables firewall is a complex piece of software. If you need assistance with configuring it, visit the PIAF Forum for some friendly assistance.

We’re pleased to introduce our latest backup and restore utilities for Incredible PBX. Running /root/incrediblebackup will create a backup image of your server in /tmp. This backup image then can be copied to any other medium desired for storage. To restore it to another Incredible PBX server, simply copy the image to a server running Asterisk 13 and the same version of the Incredible PBX GUI. Then run /root/incrediblerestore. Doesn’t get much simpler than that.

Every time you log into your server as root, Incredible PBX will ping the IncrediblePBX.com web site to determine whether one or more updates are available to bring your server up to current specs. We recommend you log in at least once a week just in case some new security vulnerability should come along.

In the meantime, we encourage you to sign up for an account on the PIAF Forum and join the discussion. In addition to providing first-class, free support, we think you’ll enjoy the camaraderie.

Your next stop ought to be learning about the three dozen applications included in Incredible PBX. We’ve put together this tutorial to get you started. Enjoy!

And, to our friends at Google, thank you!

Some Recent Nerd Vittles Articles of Interest…

Today we’re paying a fresh visit to our favorite virtual machine platform and introducing a turnkey unified communications server for home, SOHO, and small business use. Unlike last week’s platform that required a $35 investment in a Raspberry Pi 2, this week’s offering requires zero hardware investment. And you still get the same software collection at the same great price, totally free… as in beer. The VirtualBox® platform runs atop any Windows PC, Mac, Linux desktop, or Solaris machine and uses a small portion of the desktop computer’s available resources. Other than that, everything works just as if you were running your PBX on standalone hardware.

Today’s release is built atop the new Scientific Linux™ 6.7 platform and features the latest LTS release of Asterisk® 13 and a terrific collection of GPL modules from FreePBX® 12. It also is our first opportunity to showcase one of our new Certified Incredible PBX™ builds. Certification is a new process that involves rigorous testing of the entire Incredible PBX platform to verify that every component is not only reliable but also works in harmony with the rest of the pieces of the unified communications suite. You’ll find all of them here. Think of Incredible PBX as the 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 recognition and dialing, SMS messaging, free fax support, reminders and wakeup calls, and SECURITY! The other major advantage of Incredible PBX on the VirtualBox platform is a turnkey install in less than 5 minutes! Just choose the Windows PC, Mac, Linux desktop, or Solaris machine and off you go.

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 13 and the same GUI platform 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.

Getting Started. For today, we’ll provide a refresher course on loading VirtualBox and the new Incredible PBX virtual image. 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.

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 although VirtualBox 5 can be a little quirky on some platforms. If you have trouble with getting a clean status report with VirtualBox 5, just drop back to the final release of VirtualBox 4. We tested VirtualBox 4 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. And here’s a link to the latest Oracle VM VirtualBox User Manual.

A word of warning on the front end. The Incredible PBX image featuring Asterisk 13 for VirtualBox is huge, about 3GB! There are two ways to grab the .ova image. You can either download the image directly from here or from SourceForge. Or, for better performance, download the torrent and let multiple servers help you get the software quicker. Usually download times are cut by 70% or more. The MD5 checksum is 6037b8319ce9070270474889af76f86d.

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. That’s all the configuration that is necessary for your Incredible PBX Virtual Machine. The rest is automagic.

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 SL67 OS boot procedure 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.

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 admin password and email address for AvantFax: /root/avantfax-pw-change
• Set your web apps admin password: htpasswd /etc/pbx/wwwpasswd admin
• 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
• Login to your NeoRouter VPN server if desired: /root/nrclientcmd

To access the Incredible PBX GUI with a browser, point to the IP address of your virtual machine and login as admin with admin password set above. 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.

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 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

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

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!
