[asterisk-dev] Channel support for GSM devices

[Odicha]

Some tests made. One OpenVox G400P working on asterisk 1.6.1 (4 gsm 
channels). Now working on Huawei modems...
My idea.

One gsm library - jagsmlib (just another gsm lib... original....). It'll 
be as libpri for gsm channels...
A mod for chan_dahdi, it adds support for gsm channels...
channels for dahdi (per hardware basis)
It's only going to support voice till there's a clear and unique way to 
"move" text messages in asterisk, so I'm not going to do nothing about 
sms till that moment... We can add support for it easily later
