Abstract:
Provided are methods, devices, and systems for maintaining a SIP survivable User Agent. The present invention is adapted to allow the User Agent to detect the status of the network, thus providing the User Agent to perform failover/failback operations. The User Agent may be adapted to determine the status of the network based on its own monitoring mechanisms and/or based on messages received from other network components.
