In survivability mode, incoming PSTN (Public Switched Telephone Network) DID (Direct Inward Dialing) calls will be routed to the DN (Directory Number) associated with the phones registered on the RG8700. Calls directed to phones which are no longer reachable can be directed to a single answering position. For outgoing calls, TKGs (Trunk Groups) will continue to direct calls in an orderly manner.
Since the Lotus Sametime Unified Telephony routing mechanism is no longer available, some PSTN services may no longer be accessible for the brief time until communication with the Lotus Sametime Unified Telephony is restored.
