Abstract
When Internet telephony service is provided using SIP protocol, The session initiation protocol (SIP) does not define a keepalive mechanism for the sessions it establishes. Although the user agents may be able to determine whether the session has timed out by using session specific mechanisms, proxies will not be able to do so. The result is that call stateful proxies will not always be able to determine whether a session is still active.
