  • Connection Preserving Failover/Fall back
    • Existing stable calls where the talk path exists between two or more parties are not dropped when the media gateway fails over to another server or falls back to the primary server
    • Connection cannot be preserved for:
      • calls that are not in stable state (on-hold, ringing, etc.)
      • calls using IP or ISDN-BRI trunks, or ISDN stations
  • Auto Fall-back to Primary Connection
    • The Media Gateway will automatically reconnect to the primary server when available after having failed over to the Local Survivable Processor (LSP)
    • Automatic reconnect can be administered to allow for orderly return to service without manual intervention
