sip uses UDP but the elements that are in topology of your environment have to use TCP sometimes.on the other side ACK is a method for SIP that is a kind of "action reminder" if you search RFCs you can understand that ACK is used for UAs and SIP elements (redirect servers etc...) internally for functinality.good day,halit> Date: Mon, 16 Jul 2007 22:02:48 -0700> From: nazeema_guttur at yahoo.com> To: discussion at sipforum.org> Subject: [SIPForum-discussion] SIP uses TCP or UDP??> > hi,> SIP works on TCP or UDP?> > if UDP then why do we get ACK> > > >  > ____________________________________________________________________________________> Need Mail bonding?> Go to the Yahoo!
