As pjsua manual <http://www.pjsip.org/pjsua.htm> states, there are several options that can help you: --play-file=file --rec-file=file --auto-play --auto-rec BTW, if you plan to measure round-trip delays, there is also "mtr" utility (try "apt-get install mtr-tiny") which uses ICMP, but with its options --interval SECONDS and --psize BYTES you can easily emulate RTP traffic. -- Roman Imankulov roman at netangels.ru
