Hi,
Does the scenarios uac/uas work when uas is contacted via a proxy ?
In my setup the uac client is contacting a remote sipp uas via a
proxy(kamailio).
This fails because the uac scenario sends the ack to the proxy rather than
the remote client. The proxy sends the ack on to it's own port 5060
(local loop)
and generates unknown user as a spam control measure.
Should I change the uac to send to the uas port directly or is the
proxy misbehaving?
Well I did pick up the the Contact address via next_url and used the
setdest to set remote_ip
and that worked for the subsequent ACK, but for the following BYE,
remote_ip is again set to the proxy without intervening messages.
cheers
