Re: [Sip-implementors] Timeout condition in hold state

[Aditya.R.S]

Hi,   >Is there any provision in SIP to take care of the timeout in holding condition ? Yes One way of getting out is through periodic refresh of the session between the participants in a session. Draft "draft-ietf-sip-session-timer-08.txt" suggests the addition of the "Session-Expires" and "Min-SE" headers that help in refreshing a session periodically.   A single UA in a session supporting "draft-ietf-sip-session-timer-08.txt" can handle this situation.   Let me know of any other way out !   Reg Aditya.R.S Knowledge Systems Pvt Ltd 470, East End Main Road 9th Block Jayanagar Bangalore 560 069 Telephone: +91-80-6545252 ----- Original Message ----- From: Nagaraj To: [EMAIL PROTECTED] ; [EMAIL PROTECTED] Sent: Monday, March 25, 2002 11:45 AM Subject: [Sip-implementors] Timeout condition in hold state Hi all,     Consider a situation:   ua-A  establishes a SIP session with ua-B. After some time ua-B requests for a hold by using INVITE method. ua-A goes into "hold" state and waits for ua-B to resume.   If now network goes down at ua-B, and he disconnects without sending any more SIP messages, how ua-A will come to know about it.   Is there a mechanism for determining timeout value for ua-A, so that he wont wait forever.   Regards,   -Nagaraj.   Nagaraj.
