Hi Zeinab,

                  In simple language we can explain SIP 183  message as a Provisional Ack message for a call which is still being set  up.

.

If we recieve a Session progress 183, then the media will start flowing from the farend to our side and vice verca.

If you make a call from your side to the PSTN, then , There will be an

Originating               Terminating

Gateway                    Gateway

    --------------------------------->

           INVITE   

    <---------------------------------

          100 Trying

   <------------------------------------

     183 Session Progress (One way SDP)

   <========================

       One way voice path

   <------------------------------------

               200 OK     

     ------------------------------------>

               ACK

<========================

           Two Way Voice Path

then we get Bye, Release, Release complete, and then 200 OK  .

hope this helps.
