Hi Max and Bogdan-Andrei, Very grateful for your comments. However, at a first glance, I find that RFC 4208 says in Section 8.3: "When the current time equals or passes the session expiration for a session, the proxy MAY remove associated call state, and MAY free any resources associated with the call. Unlike the UA, it *MUST NOT* send a BYE."
If I don't misunderstand it, RFC 4208 requires a proxy server not to send a BYE to the other user agent in my issue. RFC 4208 seems to suggest that the two UAs are responsible for whether their session has timeout. So I guess I don't have to implement any mechanism to terminate that kind of dialog in my issue. Any comment is appreciated.
