User failed over to Branch Survivability Server

Last Updated : May 01, 2016 |

This event occurs when one or more users fail over to their branch survivability server due to a loss of connectivity with their core Session Managers. Users active on the Survivable Remote Session Manager (BSM) do not receive the full service of the core. The only sequenced application available in survivability mode is the Communication Manager application for the Communication Manager subtended by the branch. To place calls from a branch SIP user to a user outside the branch, dial the call using the public number of the user. To place calls to a branch SIP user from outside the branch, dial the public number.

The possible causes are:

  • Lost connectivity between the branch and core.

  • The Session Manager experienced partial network outages.

  • The core Session Managers are overloaded.

  • The core Session Managers are in the Deny New Service state.

  • The core Session Managers are in an error state which is preventing consistent survivability state service.
