	SRTP has nothing to do with the transport protocol, and in fact works 
over TCP or UDP, although common sense says that it doesn't make much 
sense to transport audio (either RTP or SRTP) with TCP. :)

	There is some effort underway to support SIP over TCP, which can make 
some sense.  Note that SIP and RTP are two separate (although often 
confused) protocols that can use a mixture of UDP/TCP (TCP for the 
signaling - SIP, and UDP for the audio - RTP).  Or, %100 UDP as it is in 
Asterisk now.
