Hi,
I rarely use pcap_play.
But if i had to solve this, I would eliminate the payloads in the list that
don't correspond to the payload present in the pcap file. Because if the
peer selects the "wrong" payload, it will discard the packets being sent.

Why do you add the SIPp mailing list digest to your post? It doesn't have
anything to do with your problem. Why force people to read what is not
important. We are all volunteers here. Save use some time.
I almost gave up replying to this as I use GMail and it took almost 1 minute
to prepare the editing box for reply.
