Abstract
A method and apparatus for terminating a communication session at a first communication device that had established a communication session with a second communication device in response to a determination that the first communication device has not received any media packets from the second communication device within at least one predetermined time period. In the event the first device determines that no media packets have been received from the second device within a first predetermined time period, a probe is sent to the second device. If a positive response is not received by the first device within a second predetermined time period from the sending of the probe, the first device terminates the session. If a positive response is received by the first device in response to the probe, the first device transmits additional probes during the session whenever media packets are not received from the second device within a third predetermined time period and the session is terminated by the first device if a response to the respective probe is not received within the second predetermined time period.
