VoIPowering Your Office: PBX in a Flash�Lean, Mean Asterisk Machine

A new iPBX software appliance has hit the wires, PBX
in a Flash
. This is the brainchild of the folks at Nerd Vittles, who have
spent the past couple of years writing high-quality how-tos about [email protected]
(which later became Trixbox) and general VoIP guff. Actually that’s “folk” singular,
as Nerd Vittles is the technology blog of Ward Mundy, who apparently has a lot
of time to devote to tinkering and writing. (Which sounds to me like the perfect
lifestyle.) Mr. Mundy made the mistake of programming his own personal Asterisk
server to find him wherever he went, so I was able to track him down and have
a good phone conversation with him about this new project.

When Trixbox was acquired by Fonality, it moved in a direction that wasn’t
entirely in harmony with Mr. Mundy’s goals. So rather than starting a new blog
devoted to railing about it, which is an acceptable but not-all-that-productive
option, he decided to package his own Asterisk + operating system + other neat
stuff bundle, and the result is PBX in a Flash. PBX in a Flash targets three
distinct user categories: do-it-yourselfers who run their own Asterisk servers,
users who would rather pay for some help, and developers.

Birthing the baby
PBX in a Flash was assembled in an amazingly short three weeks. It is not a
beta release, but a mature, production-ready release. Mr. Mundy is sad that,
so far, only a single bug has been found, so if you’re into bug-hunting this
could be a worthy challenge.

The four maintainers of PBX in a Flash—Ward Mundy, Joe Roper, Tom King,
and Tony Vincent—were able to put this together so quickly because they
are all experienced gurus, and because the code is based on an existing successful
commercial Asterisk implementation that was maintained by Mr. Roper. (Which
seems quite generous on Mr. Roper’s part.)

Lean. Mean. Ready to rumble.
Unlike [email protected], PBX in a Flash is slender from the git-go. Rather than
throwing in the kitchen sink, lawnmower, and stray livestock, PBX in a Flash
includes just the essentials for a comfortable, functional Asterisk-based iPBX
with nice graphical management and configuration utilities. It includes:

  •  CentOS 5 Linux
  •  Asterisk 1.4.13
  •  FreePBX 2.3.1
  •  Apache
  •  MySQL
  •  PHP
  •  phpMyAdmin
  •  Perl
  •  Festival-Lite, for text-to-speech

Of course you’re not stuck with the default installation, but can easily add whatever you want. It’s easier to add packages than to wade through a complex installation and figure out what you want to remove, and FreePBX makes it very easy to add new modules.

Mr. Mundy has big ambitions for extending PBX in a Flash, and plans to add custom scripts for adding other classic Nerd Vittles goodies like weather reports, news feeds, podcasts by phone, telephone reminders, and TeleYapper. No, not TeleZapper, which is an anti-phone-spammer weapon, but TeleYapper, which is for organizations that need automated calling trees to distribute information. Like churches, schools reporting weather closures, political organizations, and so forth.

He is negotiating with various VoIP service providers to include some free trials for DID (Direct Inward Dial) and PSTN termination services. He is also working towards providing monitored services and managed hosting, for folks who would rather pay someone else to do the work. But do-it-yourselfers will not be abandoned: PBX in a Flash will always be free and open source, with no propriety or off-limits bits. All source code and scripts will always be readily available, and soon developers will have a special script that turns their Asterisk box into a complete Asterisk development platform.

PBX in a Flash is available in two versions: a native Linux installation, and
a VMWare image to install on Windows. The combination of VMWare and Windows
is going to hurt performance, and you’re still going to have to know how to
run Linux, but it’s a nice way to get acquainted without needing a second PC.
Remember that an Asterisk server requires some muscle&#151you’re using inexpensive
PC hardware to do what used to require expensive telephony hardware, so don’t
complain. A gigabyte of RAM and a modern dual-core CPU will do nicely for starters,
and these days won’t break the bank.

Be sure to consult the detailed
installation manual
. You’ll need to be connected to the Internet. Installation
is pretty straightforward, but it has several stages. The first one is installing
CentOS; then the installation script will download and install the iPBX software.
There are some essential post-installation chores which are detailed in the
manual&#151these are important, so don’t skip them.

Users of Trixbox will find a handy migration script here.

Resources and Help
The PBX in a Flash gang are pretty cool folks, and won’t yell at you for not
already knowing everything. There are good forums
and an IRC
, plus all the documentation already mentioned, so you’ll have plenty
of help. Come back next week, and we’ll fire up PBX in a Flash and take it for
a test drive.
