RFC 3261 clearly states that a failure of a transaction within a dialogue does
not necessitate tear-down of the session. For example, if a re-INVITE fails,
the session continues with the previously negotiated information. Only in the
case of a 481 or a 408 should the dialogue be torn down.
Out o
An example - An UAS will respond with 500 response when it receives
out of order requests.
This might result in session tear down.
TCP handles OOO packets in a better way and won't let such situation occur.
I think one would use TCP (i.e reliable L4 ) when SIP reliabilility
alone is not enough.

I don't understand it. You are speaking about *network* level reliability
(level 4) but since we are talking about SIP what we need is *application*
level reliability (level 5)

Yes, but also note that SCTP doesn't exist in the real IP world yet...
PS: Operators network (SMS = 0.25€ in 2009 year) is not what I mean "IP
world".

Is there a rule for selecting the the transport layer protocol like when to use
TCP or when to use UDP
