[OpenSIPS-Users] I have a query regarding loadbalance of opensips .

[Bogdan-Andrei Iancu]

Sasmita,

OpenSIPS can open a new TCP connection towards an UAC IF:
     1) the registered IP is public
     2) the UAC is not behind a NAT.

The 477 reply is generated by the inability of OpenSIPS to open a TCP 
connection - you can see some error messages into the logs too.
