so sipcapture is executing the request route block from the config even 
for packages received on the raw sockets. In this case it does not set 
the socket and its string representation...

Not sure yet the best place where it should be fixed: in usrloc (to test 
for sock and sock_str) or in sipcapture, to set this fields as most of 
the other config function. The second will be safer overall, but might 
not be an usable socket for sending (if someone will attempt to do 
lookup location and relay).

Cheers,
Daniel
