This makes no sense at all. If a client behind NAT opens a TCP connection with a server outside, and later the server is restarted and the TCP communication terminated, there is NO WAY for the server to open a new TCP connection with the client. Of course, there is NAT! > To resolve problem of NAT. Peer should send request with rport > parameter in Via header. This also makes no sense at all. rport is JUST useful por SIP over UDP.

And again, another ugly comment. Do you know how TCP responses are sent?? You are *totally* wrong. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
