Hi Victor,
I think you are mixing 2 different concepts:
- SIP domain (used by domain module) and which has the meaning of domain
to be locally served (a domain may be served by multiple SIP servers)
- IP of a server, as listener for SIP traffic
In opensips, RR module, to see if a Route hdr points to itself, checks
the RR content both as IP (against local listeners) and as domain
(against the domain table) - this last check is the one you do not have
in kamilio.
Now, if you want your opensips not to handle the Y.Y.Y.Y ip as local,
why do you place it in domain table ? make no sense as it is not its IP.
Regards,
Bogdan

Hi All!
I have the following situation with loose_route() which looks strange
for me.
X.X.X.X is OpenSIPS-1.7.0
Y.Y.Y.Y is next-hop SIP device
Z.Z.Z.Z is SIP UAC
The following ACK come to OpenSIPS

--------------
If Y.Y.Y.Y is known as local domain from domain table, then
loose_route() decide to send ACK to himself
I hope this request will be send to Y.Y.Y.Y because topmost Route
indicate this proxy and it will be removed and next Route will be used
to route request
If Y.Y.Y.Y is NOT known as local domain (deleted from domain table)
then request routed properly
Also, I try old kamailio-1.5.1 with this configuration and request
routed as expected by me
Is this bug/feature or my misunderstood of loose_route (again?! :-) )
Thanks!
