[OpenSIPS-Users] drouting and tcp transport

[nick at uni-petrol.com]

UAC--udp--UAS--tcp--UAS 

Additional information: it's only happens
when UAC send INVITE with ";transport=udp" attribute: 

INVITE
sip:xxxxxxx at sip.domain.com;transport=udp SIP/2.0

So question is how to
avoid appending transport attribute that come from UAC when forwarding
this INVITE to upstream UAS?

Thanks in advance.

";transport=udp" to INVITE requests even when I specify diefferent
transport in dr_gateways.
