you do not need it to set the socket before the record routing. When the 
sip request is reeived from a different IP interface than one used for 
sending, you will see two Record-Route headers.

For the messages within the dialog (e.g., re-INVITE, BYE), loose_route() 
and t_relay() do all the job, so you do not need any forcing of the socket.

Cheers,
Daniel
