[Freeswitch-users] Wrong RFC2833 in SDP on NEC phones

Dear list, Some Nec phones sends DTMF RFC2833 with payload 101 during the call, but have negotiated a different one on SDP. When integrating with pabx NEC SV8500 and using phones DT700ITL32D-1 we notice this phone sends the following INVITE packet and RTP packets: http://pastebin.freeswitch.org/11433 Whole wireshark capture file is on http://gregianin.org/teste_voice_rfc2833.pcap Is there any parameter to tweak FS in such a way to force understand 101 packets as DTMF? Thank you in advance! Fernando Testa PS: On pcap you have the following IPs: FS at 10.91.10.210 Nec Pbx 10.91.10.22 phone 10.91.10.85
