Not sure if this will work, but try to include an UPDATE case in this if of
the function call::process_incoming() of call.cpp file and see what happens!
#ifdef PCAPPLAY
/* In case of INVITE or re-INVITE, ACK or PRACK
get the media info if needed (= we got a pcap
play action) */
if ((strncmp(request, "INVITE", 6) == 0)
|| (strncmp(request, "ACK", 3) == 0)
|| (strncmp(request, "PRACK", 5) == 0)
&& (hasMedia == 1))
get_remote_media_addr(msg);
#endif
