Description

The current service behavior is as follows: if OS contains several network interfaces and the service has a listening TCP socket (or UDP with 'mhomed=1' setting) on the second (third, fourth and so on) interface, then the outbound SIP messages will be always sent from the first (default) interface.
These changes make the outbound SIP messages always going through the network_interface/address, which is taken for listening by service.
