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
-------------- next part --------------
