Hello,

is the protocol scheme 'sips'? Because if the scheme is 'sip', the lack of transport parameter implies use of UDP.

Cheers,
Daniel

Hi Daniel,
      I solved the problem by add "transport=udp". Thanks anyway.

Cheers
Jesse

Hello,

if you set r-uri to a UDP address, then you can just use t_relay(), and everything needed should be done by kamailio. Be sure you do record_route()/loose_route(), so the requests within dialog are also routed properly.

Cheers,
Daniel

Hi everyone,
     I have a kamailio server with TLS enabled. I need to forword UAC request to a PSTN gateway which only support UDP. Is it possible that kamailio can translate this with proper configuration? How can i do this?
