[SR-Users] Kamailio TCP Proxy

[Daniel-Constantin Mierla]

Hello,

Contact header is not used for routing of current message, it is there
to indicate to the receiver where to send back follow up requests.

As I can see in the trace you attached, the request URI doesn't have any
transport parameter, which means to use UDP, the transport that kamailio
uses for relaying.

You can enforce a transport for kamailio, by adding transport parameter
to uri or using some dedicated functions -- see the readme of tm module.

Cheers,
Daniel
