Sipp has a function to transfer data media as audio and video. Next I type SDP as following : v=0 o=- 3487063231 3487063231 IN IP[local_ip_type] [local_ip] s=SJphone c=IN IP[media_ip_type] [media_ip] t=0 0 a=direction:active m=audio [fileld4] RTP/AVP 0 8 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=sendrecv with field4 = 10000 , the Sipp send media from port 0 and I use Wireshare to capture the packet INVITE, in message INVITE, SDP has port 10000 if I replace [field4] par [auto_media_port] Sipp chooses automatically a port as port 6000. And the scenario runs well. But I have tried to replace [field4] par fixed port 6000 .... Sipp send media from port 0. I think that Sipp has error in sending media with fixed port. Is this a bug of Sip ?
