[Asterisk-Dev] codec issues

Hi,

I have two users using EyeBeam with all codecs enabled.
sip.conf has canreinvite = yes on the general section.
In all cases peer1 starts the call to peer2.

If I put disallow=all; allow=speex on both peers, the connection is established, EyeBeam displays that the channel is using Speex, but just a second later it blinks and changes into gsm, while the other EyeBeam does the same, but changes to g711.

If I run a "sip show channels" at this moment, situation, it show the following:

ippeer1   peer1  30b0889c00b  00103/00000   speex
ipasterisk  peer2   900aa26e6e6  00102/00001   ilbc

Isn't it totally inconsistent? Each EyeBeam displaying a codec, sip channels displaying other codecs???


If I put disallow=all; allow=ilbc on both peers, the connection is established, EyeBeam displays that the channel is using iLBC, but one user can hear the other well, while the other can't here anything (just noise). Asterisk log displays  "rtp.c:509 ast_rtp_read: Unknown RTP codec 98 received".

Now, sip show channels shows the following:

ippeer1   peer1  6a2f3a76257  00103/00000   ilbc
ipasterisk peer2   cf4e7917d56  00102/00001   ilbc

Now it seems consistent, but peer1 cannot hear peer2.

Thank you for your help!
Dov
