Hello,
I have confusion to cancel the UPDATE request and INVITE.
Please consider the following scenario.
UAC UAS
------------INVITE(SDP)------->
<-----------100 Trying--------
<-----------183 ( SDP))-------
------------PRACK------------------>
<------------200 OK(PRACK)-----
--------------UPDATE(SDP)------->
Now UAC want to terminate the session. What message UAC Should send to
UAS?
one CANCEL message is enough or It should send CANCEL for UPDATE and
then CANCEL for INVITE.
In UAS side,
If UAS receive CANCEL request, how it will identify whether the CANCEL
for INVITE or UPDATE.
the same problem may happen for cancelling PRACK also.
Could you please give your view on this.
Reagrds,
karthic kumar J
