Patent ID: 7853696

Claim:
A method comprising: receiving, at a presence server, a command to watch a first campee endpoint and a second campee endpoint, the command received from a plurality of camper endpoints currently camping on the first campee endpoint and the second campee endpoint; determining that the first campee endpoint has a presence state that is currently available to participate in a communication session with the camper endpoints, the first campee endpoint, and the second campee endpoint; determining that the second campee endpoint has a presence state that is currently available to participate in the communication session; setting a timer in response to the first and second campee endpoints being available; notifying a first camper endpoint of the availability of the first and the second campee endpoints when the timer expires by: sending a first status indicator to the first camper endpoint indicating that the first campee endpoint has a presence state that is currently available; and sending a second status indicator to the first camper endpoint indicating that the second campee endpoint has a presence state that is currently available; and notifying a second camper endpoint of the availability of the first and the second campee endpoints if the first camper endpoint fails to complete a call to the first and the second campee endpoints by sending the first and the second status indicators to the second camper endpoint.
