[Freeswitch-users] Yet another DTMF question

[Travis Stutsman]

Call has been answered - I can hear the IVR.  Payload type is 101 - packets
on both ends verify this.  SDP example follows:


2011-01-18 19:10:13.579728 [DEBUG] mod_sofia.c:681 Local SDP
sofia/internal/1000 at x.x.x.x:
v=0
o=FreeSWITCH 1295351291 1295351292 IN IP4 x.x.x.x
s=FreeSWITCH
c=IN IP4 x.x.x.x
t=0 0
m=audio 26522 RTP/AVP 8 101
a=rtpmap:8 PCMA/8000
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-16
a=silenceSupp:off - - - -
a=ptime:20
a=sendrecv
