Hi Is there a reason why freeswitch sends a double DSP payload in the SIP invite from a gateway? The problem is that the payload is too big that It gets fragmented and then it fails because of that. v=0 o=FreeSWITCH 1509455513 1509455514 IN IP4 208.90.97.6 s=FreeSWITCH c=IN IP4 208.90.97.6 t=0 0 m=audio 16724 RTP/AVP 0 101 13 a=rtpmap:0 PCMU/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=rtpmap:13 CN/8000 a=rtcp-mux a=rtcp:16724 IN IP4 208.90.97.6 a=ptime:30 m=audio 16724 RTP/AVP 18 0 8 3 101 13 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=rtpmap:3 GSM/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=rtpmap:13 CN/8000 a=rtcp-mux a=rtcp:16724 IN IP4 2 Any comments? -- Luis Daniel Lucio Quiroz CISSP, CISM, CISA Linux, VoIP and much more fun www.okay.com.mx Need LCR?
