[Asterisk-Dev] mulitpart mixed application sdp

[Jerry Geis]

I have modified the source to (chan_sip.c) to not return on error of the multipart sip.
I have inserted manually the values for "m = " and "c = " that I got from the debug output.
I am very close to getting something to work.
The problem is I dont ALWAYS get audio.

AS you can see below audio formats are found.

I posted to this list as I thought users would not be technical enough for finding a solution
to connecting to the nortel CS 1000.

ANy ideas on why I dont always get audio???

THanks for your thoughts.
