[Freeswitch-users] G.722 negotiation issue with AVM Fritzbox

[Roland Hänel]

My codec selection list is:

            <param name="inbound-codec-prefs"
value="G722,PCMA,PCMU,H264,H263,H263-1998,H263-2000"/>

and I'm running a git version bebf3028d87cfcfbf094373e83ef92a391049d1f (4th
Jan 2012). G722 is first because I want high quality to be selected if
offered by the calling device (if I put PCMA first, then this gets selected
without any problem).

All in all, I think I can agree to what Anthony said, the first mistake is
clearly a Fritzbox problem, and there is some risk that other things might
break when we try to fix a thing that is already broken. Maybe I'll just
implement a workaround to dynamically modify the codec list if I see a
Fritzbox in the user-agent string...

Greetings,
Roland
