[OpenSIPS-Users] Listening on two different ports? Or two different addresses

[Bogdan-Andrei Iancu]

Hi Kenneth,

not sure what this openims is, but if something from the OpenSIPS 
family, the normal behaviour is to preserve the socket (same inbound 
socket will be used for outbound socket). But there are 2 exceptions:
    - if you cannot route across interface (totally different networks), 
you may enable mhomed option and opensips will try to autodetect the 
right outbound interface based on the destination IP
                http://www.opensips.org/Resources/DocsCoreFcn16#toc58
    - using from script force_send_socket("socket") - to force a 
specific outbound interface.
                http://www.opensips.org/Resources/DocsCoreFcn16#toc101

Regards,
Bogdan
