This appears to be more concerned with specific call processing issues and policies than with SIP. It should be handled outside of SIP. A similar concern could be raised about long duration calls. A stateful proxy will reserve resources for all calls. If no activity is seen on a call for a significant period of time, what should be done? Currently in the PSTN in North America, calls are terminated in the network if they have been up for 48 hours to preserve resources. I do not see this being as SIP issue as well although it will need to be implemented on SIP-enable systems.

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. Bhat. Smart Yantra Technologies Pvt Ltd #57, 3rd Floor, HMT Layout Behind R.T.
