Hijacked by RTFM to la-la land
I keep a vigilant eye on Google Alerts. To be more exact, I’ve got a few alerts defined, in accordance to subjects that interest me. Two of these subjects are Asterisk and FreeSwitch. Recently, the following had been posted on a personal blog:
Asterisk just seems to come from a different world than what I am used to. Inflexible and problematic. Very long configuration files with ancient syntax. Now I’m far from pretending I’ve used Asterisk enough to understand it pros and cons well, but I have a decent software development experience and I can tell when something “smells.” I didn’t want to build our system (that I want to be flexible and scale well) on some old technology that is only living from its past.
And (most importantly) there are many people experienced with both Asterisk and Freeswitch favoring the latter: Anders Brownworth, Jonathan Palley (creator of Telegraph, a Rails plug-in that lets you talk to Freeswitch), or of course the creator of Freeswitch (and former Asterisk developer!) Anthony Minessale himself.
Reading the above simply flames me UP – WHAT A LOAD OF BULL!
The writer admits that: “Now I’m far from pretending I’ve used Asterisk enough to understand it pros and cons well, but I have a decent software development experience and I can tell when something “smells.”” – If he’s such a worthy developer, the above simply proves that he’s simply an RTFM!
Asterisk provides a multitude of methodologies for configuration management, dialplan logic programming, programmatic API structures – basically, all the tools you need to go about and create your application. While I admit that FreeSwitch is slightly better at the “Core Switching” environment, implementing a near true Soft Switching architecture – Asterisk is a totally different thing.
A while back I decided to develop a couple of my better systems on FreeSwitch, as a test of my abilities. To see if I can be as proficient with FreeSwitch as I am with Asterisk. I re-developed the applications on FreeSwitch from scratch, however, FreeSwitch’s somewhat annoying XML configuration structures made it a hell for me to develop something that I would ask my customers to put their money on.
I started working with Asterisk in 2002, and starting 2003 I tried to have people in Israel start using Asterisk. I can honestly say that the first ever true adaptation of Asterisk in Israel came about only late 2005, and even that wasn’t for mission critical applications. Asterisk had achieved a point in which it is now considered a valid replacement for classic IN and NGN applications and engines, such as SigValue. I suspect that FreeSwitch will become a more dominant contender in that part within a period of 18 to 24 months, as its developer community will grow – time will tell.
In my large installations, I like using Asterisk as my IVR/Application engine envrionment and using FreeSwitch as my routing and LCR environment, simply because it’s capable of handling slightly more SIP-to-SIP connections than Asterisk – but that is the only reason, all the rest is Asterisk.
Both projects are wonderful tools, each one with its own set of strengths and weaknesses. Learn how to balance the use of the two, utilize the best of both world – and stop being a bloody purist, that’s exactly what leads to poor technologies such as Microsoft and poor life practices, like wars and terror.
