On 10.0.71.24 I run a software VTC client configure to use SIP (Polycom Telepresence m100). The URI is sip:10.0.71.24@10.0.71.24 On 10.0.71.109 I run the live555 command line tool playSIP calling 10.0.71.24. playSIP creates only a zero length file named: audio-PCMU-1 Any advice? The problem here is that our SDP parsing code currently only notes the first RTP payload format number in a SDP "m=" line (because our RTP processing code currently doesn't handle more than one RTP payload format code being used in a RTP stream). Your server's SDP "m=" line is m=audio 8000 RTP/AVP 118 115 114 113 99 98 97 102 101 103 9 15 0 8 119 which is legal, but our code would be able to handle it if the "0" (i.e., PCMU) payload format code were first - e.g. m=audio 8000 RTP/AVP 0 118 115 114 113 99 98 97 102 101 103 9 15 8 119 because "0" (i.e., PCMU) RTP payload format happens to be the only RTP payload format that's used in this stream.
