That's what the rfc says (assuming UDP is used for in-dialog
communication)
" A UAC MUST NOT initiate a new out-of-dialog MESSAGE
transaction to a
given URI if there is a previous out-of-dialog transaction pending
for the same URI. Similarly, A UAC SHOULD NOT initiate overlapping
MESSAGE transactions inside a dialog, and MUST NOT do so unless the
route set for that dialog uses a congestion-controlled transport at
every hop."

Subject: Re: [Sip-implementors] Overlapping requests
From: "Dima Polsky" <[EMAIL PROTECTED]>
What requests are allowed to overlap (several concurrent requests
with
the same dialog id) ? I know that for MESSAGE, INVITE and UPDATE it
is
forbidden, what about INFO, NOTIFY?
I know that using a lot of MESSAGE requests within a dialog is not
recommended, but is it forbidden to overlap two MESSAGE requests?
