[Kamailio-Users] SIP proxy is expecting "Route:" header to befilled information from the last "Contact:" header ?

By the way, a short description of record-routing, strict vs loose:

http://sip-router.org/docbook/sip-router/branch/master/sip/sip_introduction.html#record_routing

If you have kamailio 3.0.0 source tree, you find it under doc/sip/ 
directory as well.

Hope it helps.
Cheers,
Daniel
