Rahul, ? Ack doesn't need a response because the receiver of the Ack stops sending the 200ok when it receives Ack. Otherwise, it keeps sending the 200ok until Ack comes or timeout. --- On Sat, 1/14/12, rahul yadav <connect2ry at gmail.com> wrote: From: rahul yadav <connect2ry@xxxxxxxxx> Subject: Re: Doubt about PRACK To: "pjsip list" <pjsip at lists.pjsip.org> Date: Saturday, January 14, 2012, 5:11 AM thanks peter ! Actually i was comparing PRACK with ACK. ACK is also an important message.
