Problem "solved".
I had added Alice as trusted for oser1 and using directly the IP of
oser2 to call Bob (no DNS yet :( ). Using the onsip config files, the
forwarding section within is_uri_host_local does not contain any line
for solving NAT of Alice's UA and this info was lost in the way to
oser2....who added oser1's IP as the contact when using
fix_nated_contact.
So,..for all those people using onsip config file be aware of this
fact if you want to forward to other proxies....

I think it is a configuration "problem" as
usual :P
I guess some info about nating is lost when forwarding from one ser to
the other....I have to dig into logs....maybe I find out the problem
soon.
Don't worry about your openser instances...

Hi all,
Might be related to the mail I just sent about the username in the
record-route or to another problem but the thing is that I can not
close the session from the callee side...i'll try to explain:
There are two users registered to two different openser instances. In
the session initiation, the record route headers contain the usernames
of both users and are therefore stored in the end points.
When the caller sends the BYE, the callee's openser receives the BYE
and rewrites the URI with the record-route (shouldn't it consider the
request for itself and check the Req-URI instead??).
NExt is the diagram and some more info...

guess F9 should be F7

F2: INVITE Bob@oser2
Record-Route:<sip:Bob@oser1;nat=yes;lr=on>
F3: INVITE Bob@bob_contact_ip
Record-Route:<sip:Bob@oser2;nat=yes;lr=on>
Record-Route:<sip:Bob@oser1;nat=yes;lr=on>
OK,ACK not shown..
F4: BYE Bob@nat_fixed_ip
Route:<sip:Bob@oser1;nat=yes;lr=on>,<sip:Bob@oser2;nat=yes;lr=on>
F5: BYE Bob@nat_fixed_ip
Route:<sip:Bob@oser1;nat=yes;lr=on>
This should be
Route:<sip:Bob@oser2;nat=yes;lr=on>
F6: BYE Bob@bob_fixed_ip
Everything ok, session closed.
But, and here comes the problem:
F7: BYE Alice@alice_fixed_ip
Route:<sip:Bob@oser2;nat=yes;lr=on>,<sip:Bob@oser1;nat=yes;lr=on>
strange, I never had any problems. Can you dump the full messages F7 and
F8 and the looping requests?

When this message arrives to ser1, it sees the
route header and, make
a strict routing process and rewrites the header in the Req-URI to
Bob@ser1.
oser1 resends itself the message, and when it receives it again looks
for use Bob in the local bindings which obviously does not exists (Bob
is in oser2).
