Restart If you want to simply force an immediate manual fail-over, then you can request a Restart from the Management Console.

WARNING

The N+M reliability strategy provides a highly available service environment. The fail-over mechanisms enable an instance of the SIP Application Module to survive failure condition(s) by migrating to a standby server where it can resume the processing of new sessions.

In such a highly available service environment the failed instance loses all knowledge of sessions started before the fail-over event. Therefore, the stability of these pre-existing sessions cannot be guaranteed. For example:

Sessions involving SIP clients will survive until the clients encounter a "no response" or "unknown call" response to a request on their active session. At that point the clients will release the session and its associated media resources.

Sessions involving the MCP SIP PRI Gateway will survive until there is no response to the SIP PRI Gateway-generated SIP "ping" to the SIP Application Module(s) handling the active sessions on the gateway. If there is no response to the SIP "ping" then the gateway will tear down the associated call and recovers its resources.

Also, sessions involving the MCP RTP Media Portal will not survive a manual fail-over because intentionally LOCKing the SIP Application Module initiates the automatic recovery of all resources (including RTP Media Portal resources) associated with in-progress sessions.

For more information, see the Configuration chapter in this document.

OAM&P strategy

The Management Module manages the OAM&P functions for the SIP Application Module. For additional information, refer to the MCP Management Module Basics and the MCP System Management Console Basics documents.
