Ops, does it mean that UDP is more suitable in a SIP proxy/server than TCP?
I really would like SIP to migrate to TCP asap.

So, if OpenSIPS tries to do a TCP connection and it takes some time
(some seconds) until a timeout occurs, then that process is unable to
handle other SIP requests. an attacker could send just 100 SIP request
with ";transport=TCP" in the RURI and a RURI host which drops the TCP
connections.
This would cause all the OpenSIPS TCP processes being blocked !! is it?
