Re: [SR-Users] UDP-TCP bridging in-dialog SUBSCRIBE

Hey Guys,

I have the following scenario:

UA1 (UDP) -> Kamailio Proxy -> (TCP) UA2

As per the signaling sample, I would expect that in-dialog SUBSCRIBEs are bridged between UDP and TCP network but for some reason this does not happen (the subscribe comes in over UDP and leaves still over UDP although tcp is present in the route headers). Are we somehow forced to mangle contact header and add transport parameter to it or the record-route headers should serve for this purpose?

Any tip would be highly appreciated.

Yes, I believe the UDP transport is chosen by default, and there must be a ;transport=TCP based-reason to relay anything via TCP.
