Asterisk codecs and packet size
Does anybody knows if it's posible or if there is some develoment in
course to be able to use longer transmit packet sizes (as long as I know
this is fixed in 20ms now) with the compressed voip codecs in asterisk
(g729, g726, gsm, etc).
I need to use asterisk to connect remote sip clients with 24kb bandwidth
lines and I'm using a licences g729 codec but because I can't increase

RTP frame size location?
Google has given me too many responses, so I'll ask the list:
Where in the Asterisk rtp source code can I find the default
millisecond frame size? I've looked around for obvious pointers, but
it's not clear. I'd like to "force" my Asterisk server to use a
certain frame size all the time. (Of course, ideally I'd like to
prefer or even force that frame size in a

}
In this case, though, chan_iax2.c doesn't necessarily know if the speex
codec is loaded..
And later, it might also be useful to have an API which takes a bunch of
SpeexBits, and gives the caller a way to s...
