send socket is set if you do force_send_socket() or assignment to $fs.

It is a bit hard to get outgoing socket while processing the incoming 
message. As a rule, if it can be routed from same socket as the message 
arrived, then that one is used.

You get the error above as you didn't added the branch, so the branch 
index was not updated and it is out of range what you want to access. 
Use $fs to get the send socket from the sip message structure.

Anyhow, not sure it really helps, as it might not be the used value at 
the end, can you give more details of what you look for?

In the very close future, you can get it via using the send_route with 
kamailio 3.0.

Cheers,
Daniel
