Thanks for your reply. I do not assume that there will be a return audio stream in all cases, or even in any case, just in the normal case. In scenarios where two-way audio is expected the lack of a return stream is an error, as would be with most commercial sip servers. So if the implantation was a command within the XML scenario it could be used to test for the dreaded one-way audio condition, with the corollary that an echo server would be present at the terminating end to guarantee return of the sent audio content. Perhaps another use under the same conditions would be to capture files for post processing to generate MOS scores (or some more precise metric). Known sent content could be compared with returned content for rigorous analysis.

It will send an outbound RTP stream, but it's up to the system-under-test to send an RTP stream back. Personally, I haven't had any need for SIPp to do any analysis of an inbound RTP stream. What sort of "analyzing/reporting" did you have in mind? Todd. ps. Sorry for reformatting your message. It came across as one really long non-wrapping line. ________________________________ From: Rod Thomson [mailto:rthom...@pofp.com] Sent: Friday, August 28, 2009 12:13 PM To: sipp-users@lists.sourceforge.net Subject: [Sipp-users] RTP testing feature I am hoping that I am wrong in my conclusion that SIPp does not process in any way the RTP stream returned (or not) from a call to "play_pcap_audio". I see error management for local socket setup and writs to same but nothing for the receive socket. I think there would be some value to analyzing/reporting the received stream. Probably something best done asynchronously or even batch post processing.
