Hi Mr.Bogdan,
Yes, the REGISTERs are replicated between the 02 SIP servers cos I can see them on 'location' tables on both servers.
I found out what is problem:
When UA1 register with SIP1, it opens the port on NAT with the public IP is of SIP1
When UA2, which is registered with SIP2, call UA1 (registered with SIP1), the SIP2 send INVITE to UA1 using correct port on location table, but the problem is here: the NAT router does not has the any information about SIP2 IP on it NATed table, so the INVITE message cannot come in to UA1.
I think this t_replicate() function does not work with my case. Should you please suggest me another solution to make a failover system (one SIP server got failure, other one can handle).
Thanks in advanced
