Is voice path before 200 OK is valid ?

 

Pls look at the call flow:

 

    A                                B

 

              INVITE

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

            180 Ringing

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

           RTP (g.723)

    <-------------------------------->

            200 OK

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

            RTP (g.723)

     <------------------------------>

            ACK

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

            BYE

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

            200 OK

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

 

Is this a valid call flow?

Can RTP come in to the scene before 200 OK?

 

- Thanx
