[OpenSIPS-Users] Local Route Socket

[Bogdan-Andrei Iancu]

Hi Samuel,

Any change of the send_socket in local route should be taken into 
consideration - be sure, by placing some xlog, that the execution gets 
to the $fs assignment. Also check the logs, maybe the socket you are 
setting there is not matching any opensips listener, so ignored.

Best regards,
