[SIPForum-discussion] Is TCP feasible for SIP??

[Medve, Steve]

Yes 

 

TCP is great for accurate delivery rather than timely delivery, and can
sometimes get into long delays while waiting for out-of-sequenced
packets or retransmissions of lost messages/sessions. It has been said
that it is not particularly suitable for real-time applications such as
Voice over IP but, I've personally used and seen it work just fine at
the larger CLEC's operating in the US.  You may also choose UDP for
these such applications as protocols like Real-time Transport Protocol
(RTP) running over the User Datagram Protocol (UDP) are usually
recommended.

Yes ,

TCP can be use, but it will attract delay.
