[Asterisk-Dev] I need help to make a simple iax switch/proxy

[Goldenear]

Hi,

I would like to make a small iax switch/proxy (I don't know which term 
is better). The need is very simple: a proxy small enought to run on a 
linux based wifi router (wrt54g) and/or simple enough to support many 
simultaneous peers. It doens't need all the bells and whistles of 
asterisk (many protocol support, voicemail, codec translation, etc ...).

It simply needs to:
- authenticate users (and keep a registered peers "database"): This is 
similar to what asterisk does with iax.conf (or realtime database), 
except that a phonenumber/extension would be directly given to a user in 
the iax.conf like file. As it's a simple proxy, it doesn't need complex 
call routing.
- connect users: each registered user could call an other one either by 
its given phonenumber/extension or by its user name. As the proxy 
doesn't support codec translation, all peers must have a least a common 
codec. If the proxy can't make a native codec bridging between the 
peers, the call is aborded. Also the proxy should always try to do 
native transfer (with a option to drop the call if it's not possible). 
When peers are "connected" and speaking, the proxy should (or must) not 
stay in the path.
- maintain an online users directory (with the possiblity to publish a 
web page), a little bit like the h323 ils system.
- register itself to an asterisk server (or a other iax switch/proxy): 
This would be useful to define a default gateway if an extension doesn't 
exist localy.
- make coffee, but only when all other features are working ;)

I hope you understand what I would like to do. Alas, I'm not a 
programmer. I only have a few C basis (php is the only language I really 
know). That's why I really need help. I guess I'm not the only one 
interrested in an iax2 softswith/proxy. I think such a project could be 
useful in many cases (e.g. be used as an asterisk frontend for iax 
peers, like SER can be for sip peers). Also, I guess that, using libiax, 
it should not be too complicated / time consuming to do for a real 
programmer :)
So I hope somebody will be interrested in this project and can help me. 
I can even offer $100 as a bounty for it :)

Any comment / suggestion is welcome

Thanks.

Nicolas
