-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rosa Maria Martinez Perallon Sent: Tuesday, January 22, 2008 4:00 PM To: [email protected] Subject: [Sip-implementors] Call-id for Dialog event package Hello, I have checked the RFC 4235 about the Dialog Event package and there is something that I don't understand. The paper claims that a subscription MUST contain the next parameters: call-id, to-tag, from-tag. Let's imagine the case for Automatic Callback. User A calls user B but he is busy. When user B hangs up, user A is alerted. What I don't understand here is how A can send a SUBSCRIBE which contains the call-id, to-tag and from-tag of B's dialog with another user in order to be alerted to the end of that conversation. How can A be aware of this information?
