[OpenSIPS-Devel] How to make OpenSIPS reuse client's TCP/TLS connection (and not try to connect on its own)?

[Bogdan-Andrei Iancu]

Hi Ivan,

The OpenSIPS reuses the TCP/TLS connection only if the connection point 
(where it tries to connect to) is already involved in a established 
connection.

In your case, maybe the connection point looks different than any 
existing connections, so a new one is opened.

Regards,
Bogdan
