But for a production system you usually do not want this feature. Practically this paragraph from RFC 3261 is non-sense as it brakes communication with SIP clients.
Residential customers SIP clients are mostly behind NAT and often do not even support TCP. Thus, automatic switching to TCP will cause problems as you can not reach the clients anymore.
Usually administrators look how to turn this feature off instead of turning it on.
is it supposed to happen even if UA binds location with UDP contact? I thought is used manly for inter-proxy/scb communication.

Hello Daniel & Klaus, thanks for your replies.
I'm going to try sip-router. And, AFAIK, at least one IP pbx works as stated by RFC (automatically switch to tcp when trying to send big messages) when registered to a sip proxy.
Thanks a lot.
