[SR-Users] [Kamailio-Users] Rewrite $tU

[Daniel-Constantin Mierla]

Are you calling msg apply changes after record_route()? Try to do 
record_route() after since it tries to discover the outgoing local 
interface which might not be set at that point.

Btw, is Kamailio bridging between two networks?

The output with '-E -ddd' will be helpful anyhow.

Cheers,
Daniel
