Ok, let's look at that (UDP vs TCP for realtime stream). Let's call the

Doesn't surprise me if Microsoft tries sending RTP over TCP. Maybe their
engineers didn't know basics of VoIP when they were programming their
communication server.

Not quite - doing SIP over TCP rather then UDP is the right thing to do
(tm). It's just that everyone started out with UDP

RTP stands for Real-Time Transport Protocol. TCP is not designed to deal
with real-time data transfer as it takes time to acknowledge packets and
re-send them if missing. All audio video data transfer happens in real time,
and it doesn't make any sense to retransmit missing packets. Real time

Adobe has not been successful in VoIP. I have worked for two companies who
were trying to make flash phones, and it always came down to the issue of
RTP over TCP. This is the primary reason there are no successfully working
flash phones out there though some companies are trying to offer service

I don't think RTP can be sent over TCP at all, it would defeat the whole
purpose of RTP. Even if you somehow manage to do so, voice quality will go
down the drain.

If you had to add firewall exceptions/PAT config for the TCP SIP traffic,
you'll also need to add the same for RTP traffic as well.
