Hi,
You can make use of Session-Timer for indicating the time for which
a session is valid.
You can refer to draft-ietf-sip-session-timer-09 draft for the details...

Subject: [Sip-implementors] how to detect that one end of a call has gone
away
After a SIP call has been established, what is the preferred way to detect
that the far end is no longer participating in the call due to some
external
cause, such as a power outage, network partition, etc? The far end did not
send a BYE, and will never send a BYE, but the near end thinks it is still
connected and continues to send out RTP packets. One possibility for
handling this situation is to detect that no RTCP packets have been
received
from the far end for some time period, and then disconnect the call.
However, many IP endpoints do not support RTCP, so this solution is of
limited use. Another possibility is to send an occasional (how often?)
RE-INVITE request to the far end, and if no response is received, terminate
the call. What is the preferred way of handling this situation according
to
the SIP and RTP standards? What is done in practice? Thank you for any
information.
