Thanks for your test artifacts David. After encountering the same problem with
your files too, I realized the problem was at the UAS end.
If I use the following "sipp -sn uas -nr -rtp_echo" at the UAS end the SDP
answer to my offer comes back with the c-line as 127.0.0.1. I need to use
"./sipp -sn uas -nr -rtp_echo -i X.Y.Z.W" at the UAS for appropriate behavior.
Thanks again and Regards,
Amit

RE: [Sipp-users] Having trouble with play_pcap_audio
indeed, working examples are nice.
here's what I use, and it seems to work fine
attached are uac_pcap.xml and rtp.cap. then run:
sudo sipp -sf uac_pcap.xml-m 1 -l 1 -mp 6999 -i 10.1.1.12 10.1.1.100
where 10.1.1.12 is the IP address on the uac
and 10.1.1.100 is the IP addr of the uas.

Subject: [Sipp-users] Having trouble with play_pcap_audio
Hello sipp forum members,
I am trying to use the PCAP (media) play feature of sipp. Following is my sipp
version built from source with the pcap feature compiled in
SIPp v2.0-PCAP, version 20071128, built Apr 14 2010, 15:48:12.
I am using the available "UAC with media" scenario from
http://sipp.sourceforge.net/doc/uac_pcap.xml. With the following usage I see
that the uac runs fine to completion of one call:
"sudo sipp -sf uac.xml -l 1 -m 1 -r 1 -nr -mp 7300 10.10.X.Y"
I also see the following output in the scenario screen:
246 Total RTP pckts sent 0.000 last period RTP rate (kB/s)
Problem is that I don't see the rtp packets at the UAS end nor can I see them
in a packet capture I run on the UAC host using tcpdump with (100%)appropriate
filtering options.
Can someone please give me some guidance or tips on how to debug this.
Thanks and Best Regards,
Voip Engg.
