Also, Don't forget that chapter 1 and appendix B of the FreeSWITCH book have a lot of excellent information. -MC https://www.packtpub.com/freeswitch-1-0-6-build-robust-high-performance-tele... On Mon, Feb 14, 2011 at 11:26 AM, Steven Ayre <steveayre@gmail.com> wrote:
All the best information is on the Wiki and in the source.

Media is processed using the RTP protocol using FS's own stack.
By control protocols I assume you mean the signalling? There are several supported: http://wiki.freeswitch.org/wiki/Specsheet#Protocols Each protocol is implemented in an endpoint module which wraps around a FOSS library that implements the protocol, e.g. SIP is implemented in mod_sofia using the Nokia Sofia-SIP stack.
There's also a management interface implemented using the custom ESL protocol. That's all documented on the wiki and there's a client using it and implementations of it in a range of languages in the source so you can write your own (libs/esl).
The only high-level design overview I know of is this one on the Wiki: http://wiki.freeswitch.org/wiki/Core_Outline_of_FreeSWITCH
Most of it is written in C (there's a little C++ there too). You can extend it yourself by writing your own C modules or using the runtime support for languages such as Lua, .NET and Javascript.
