Abstract

Storing and restoring a communication session includes establishing a communication session by exchanging dialog. Dialog from the communication session is stored to a persistent storage. Endpoints participate in the communication session to assert functionality to a monitoring module. If a failure occurs during the communication session, an endpoint receives the stored dialog from the persistent storage. Furthermore, the endpoint restores the received dialog onto a protocol stack to continue the communication session without loss of dialog.
