Abstract
A method for recovering a communication session after failure of an endpoint includes establishing a communication session between a first endpoint and a second endpoint, receiving keep alive signals from the first endpoint, detecting an interruption in the keep alive signals, and transferring the communication session with the second endpoint from the first endpoint to a third endpoint. A network device includes an interface that receives keep alive signals from a first endpoint in a communication with a second endpoint, and also includes a process or service that detects an interruption in the keep alive signals and transfers the communication session with the second endpoint from the first endpoint to a third endpoint.
