Hi Jiri,
Could you explain how to "use RFC-3261 transaction matching". Is this something I can switch on in the ser.cfg?
Thanks, Ricardo

Ok i first overlooked a problem in the messages. I think the ATA is guilty because the request URI of the ACK is not the

Thanks Nils -- indeed, that's an ATA bug -- the URIs must be the same.
To fix the problem, I urge ATA users to urge Cisco. You can use some
workarounds
(like disabling tm "ruri_matching" tm parameter in the about to be
released
ser 0.8.11 version) but ATA is the primary place to fix. Actually, the
best
thing to do with ATA is to use RFC-3261 transaction matching -- 2541
matching
has been obsoleted quite a while ago.
