Subject: [Sip-implementors] Unattended Call Transfer

Hi 

Bob sends NOTIFY "terminated" (15th message) to inform Alice that he has
successfully connected with Carol. 

Till Alice gets NOTIFY "terminated", it keeps the dialog details. 

 

My question is: 

1)       Why after doing an unattended transfer and sending BYE to Bob,
Alice would be interested in the last NOTIFY?
<Ranjit> F15 NOTIFY is sent as final response for the REFER (F5)
message. This is per protocol and may not be of interest to Alice.

2)       Do commercial UAs do anything with the body of this NOTIFY
"terminated"?
<Ranjit> No

3)       If say NOTIFY "terminated" body contains "Failure response to
Bob-Carol INVITE", what action Alice takes (generally seen) ??
<Ranjit> Nothing. If it's a failure, I think it should be some 4xx or
5xx rather than NOTIFY message.
 

 

Thanks
