This timer specifies how long the Communication Manager server preserves registration and any stable calls that may exist on the endpoint after it has lost the call signaling channel to the endpoint. If the endpoint does not re-establish connection within this period, Communication Manager tears down the registration and calls (if any) of the endpoint.

While the IP Telephone is hung-up, this is the maximum time period that the IP endpoint expends attempting to register with its current Communication Manager server. Using this timer, the customer can specify the maximum time that an IP endpoint spends on trying to connect to the Procr before attempting to register with a Survivable Remote Servers.

While the IP Telephone’s receiver is lifted, the endpoint continues trying to re-establish connection with the current server until the call ends.

This timer is started when the telephone’s registration is taken over by another IP endpoint.

The timer is cancelled upon successful RAS registration.

When the timer expires, the telephone tries to re-register with the server.

Default timer value: Dependent on the number of unsuccessful periodic registration attempts. As long as the RRJ error message continues to be “Extension in Use,” the endpoint continues to attempt registration with the current gatekeeper address.

Sample field values apply unless the endpoint is interrupted, such as by power loss, or the user takes manual action to override this automatic process:

• 20 means once every 20 minutes for two hours, then once an hour for 24 hours, then once every 24 hours continually.

• 60 means once an hour for two hours, then once an hour for 24 hours, then once every 24 hours continually.
