Hi,
I'm using Grandstream IP phone GXP2000, with Asterisk 1.4.15
I'm using g729 codec and want to use only this codec for the calls.
My normal calls are going fine. But issue is coming when I'm using the
conference from the Line1 and Line2 Option.
When I'm initiating the conference at that time, IP phone is sending the
G711ulaw for the conference call, while in my phone I've set the all codec
option to PCMU only.
Due to this I'm facing issue.
Any solution for this problem, please let me know.
Regards,
Keshav

It's your basic 64kbps pulse-code modulated ulaw companded audio codec. (For more information on PCM audio and how it works, see the "Digital Telephony" section of Asterisk: The Future of Telephony, downloadable at http://www.asteriskdocs.org/ for free.) --- Jared Smith Community Relations Manager Digium, Inc.
keshaw,
did you set your sip.conf to only allow g729?
disallow=all
allow=g729
I don't use g729 so the allow= may not be the correct syntax...
here is the config I uise:
disallow=all
allow=ulaw
allow=gsm
allow=alaw

Not sure if the latest ROM works for this or not, I have yet to try it, but my guess is no, because it is not listed on their fixes.
