Hi Edwin, I am new to the PCAPPLAY stuff but have been working on it a bit lately. I think that there is still a bit of a disconnect between the standard SIPp practices of SDP management and the handling of the .pcap file that is played out. In your case, I think that in your script you begin the process of playing the .pcap file before the UPDATE, and the .pcap play process (that is being handled in send_packets.c I think) cannot be interrupted and updated with new information. All of the packets in the .pcap file have already been prepared to play (in prepare_pcap.c I believe), based on initial 183 information.
I am not sure if there is a way to alter the SIPp code base to jump into send_packets and alter the destination port while a .pcap file is playing. Hope this helps.

The play_pcap_audio function is not sending RTP traffic to the new media ip address received in the UPDATE message. Is there a fix or a workaround for this problem?
