Hello,
i will be using the PCAP Replay with <exec rtp_stream="file.wav" />.
The problem:
SIPP send in the negotiation in the first invite as rtp media port 6000 in the 
SDP in the Media Description Header.
But sipp  send the rtp-stream on source-port 8192 not on port 6000. Our pbx 
don't accept this behavior.
The negotiation media port and the sending rtp-stream must the same port. In 
this case, sipp must send the stream from port 6000.
I tried the -mp option. If I use -mp 8192, sipp send the rtp-stream on port 
8196! Why?
If I try another port, like -mp 10000. SIPp ignore this option. In the invite,  
sipp send in the SDP in Media Description Header rtp media port 1000, but the 
rtp-stream send it again on 8192.
This problem I have is  only with <exec rtp_stream="file.wav" /> option.

I used sipp version 3.4.1 and 3.5 RC1.

Regards,
Sven Mueller
