[SR-Users] How to retrieve local socket that will be used to send a message from the branch route

[Karsten Horsmann]

Hi Patrick,

If you don't use tls at this moment, the config from sbc OS is also an good
example of using dispatcher with the socket params to select the right
sendsock and using vars to give rtpengine the right internal / external
directions. They use numbers for internal and external. To figure out where
the direction is, this config use pseudo vars for receiving local socket
