Hi I am using IMS bench SIPp. My SUT is close to a usual B2BUA. I've taken the config generated by ims_bench.pl and did the following changes: - removed registration phase (my SUT doesn't support registration) - removed all registration and messaging scenarios, leaving only uac and uas - removed route from UAC/UAS scenarios (it was taken from REGISTER response, so I don't have it and I don't need it for my simple system) - in the users_inf file, changed initial pool from 0 to 2 for all users (to consider them "registered" without runnign the registration scenario). When the UAC sipp sends INVITE, it goes through my SUT and the SUT sends it to the UAS. However, the UAS doesn't see the INVITE (but it sees recvRMT - screen dump below). I've seen on Wireshark that the INVITEs are really sent to the UAS sipp address/port. What can be the cause of ignoring them? Could it be related to the user reservation mechanism? The "From" header after going though my SUT is the same as original "From", except the tag. Can the tag be problem?
