Hi all,
Suppose we have two UAs that one invites the other, then they start a media
session and then the
connection is terminated. How exactly the media session is being terminated?
I mean, one of the UA terminates the Media Session and then sends a BYE SIP
message to the other party;
or once the media session is opened and the UA decide to close it will send
first a BYE message and
then will close the media session?
UA1 UA2
|-----------> INVITE
<-----------| 100 TRYING
<-----------| 180 RINGING
<-----------| 200 OK
|-----------> ACK
|-----------> Open Media Session
|-----------> Close Media Session
|-----------> BYE
<-----------| 200 OK
or......
