Registering with a call manager includes connecting to a first call manager and a second call manager. The endpoints register with the first call manager and send keep-alive signals to the first call manager and the second call manager. If a failure is detected in the first call manager, the system initiates a failover process. The endpoints re-register with the first call manager when the first call manager regains operability.
