My problem is simple. I have 2 hosts (host1.mydomain.com and
host2.mydomain.com located in different places) and user1 and user2
are registered in both the servers.(local DBs having identical
records).
Now, I want user1(a)host1.mydomain.com to talk to
user2(a)host2.mydomain.com without issues.
The problem you have is that a lookup() will succeed on host1 when a UAC
is registered to host2 (but stateful firewalls/NAT prohibit traffic from
ipadresses other than host2).
You can either figure out which host was used to register by looking at
the socket value in the location table (using sqlops/avp_db_query) and
send the INVITE to the other host if socket doesn't contain a local
ipadress (by simply setting $rd to the other host and setting $du to
null) or just wait for a failure route (which adds a delay) to trigger
and send the invite to the other host (again setting $du to null and $rd
to the other host).
