[Freeswitch-users] Codec Negotiation: Codec telephone-event:101:8000:20

[Mark Campbell-Smith]

Thanks Brian and Anthony.

Brian: 2 = G723-32 Do you mean G721 instead of G723-32 ?

2010-01-05 18:57:56.845029 [DEBUG] sofia_glue.c:3306 Audio Codec
Compare [G721:2:8000:20]/[G726-32:2:8000:20]

So the only codec they have offered is G723-32 (or G721), which FS
only supports as a passthrough codec.  Is that correct?
