[SIPForum-discussion] dtmf issue on the sip trunk !!

[virajith]

Hello Team,

I have an issue where dtmf is not getting negotiated . We are doing a delayed offer to pbx but the pbx ..

What the dtmf methods advertised in this  200 ok sdp sent by the pbx ?

v=0
o=IPC 425146 425146 IN IP4 XXXXX
s=IPC
c=IN IP4 10.97.232.239
t=0 0
m=audio 16442 RTP/AVP 0 8 18 101
a=rtpmap:0 PCMU/8000
a=rtpmap:8 PCMA/8000
a=rtpmap:18 G729/8000
a=fmtp:18 annexb=yes
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-15,77,84
a=ptime:20
a=sendrecv


in the ACK that we(our end) send is this...


v=0
o=CiscoSystemsCCM-SIP 2000 1 IN IP4 10.97.202.101
s=SIP Call
c=IN IP4 10.97.202.124
t=0 0
m=audio 19504 RTP/AVP 0 101
a=rtpmap:0 PCMU/8000
a=ptime:20
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-15


What the dtmf  methods advertised and negotiated?


Thanks,
Vir
