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 in the early ages of 
SIP - also think about the benefit of "TLS".

As for MS OCS: That uses TCP for SIP and UDP for RTP.

Where MS failed: OCS _only_ does SIP over TCP, whereas Asterisk _only_ 
does/did SIP over UDP. Neither is/was RFC compliant.
