After Lotus Sametime Unified Telephony processes incoming external calls arriving over a SIP or SIP-Q trunk interface, the call can be diverted to a valid preconfigured alternate destination if translation of the called party results in an invalid destination.
Only calls that fail translation receive this treatment. If calls are translated correctly, but the route assigned is unavailable or unreachable, the existing capabilities are used to handle the call.
The Lotus Sametime Unified Telephony administrator provisions this call diversion by assigning a new service to each endpoint profile. This service is activated when the called party fails translation for any reason, and the call is then routed to a destination the administrator also specifies — for example, an attendant or hunt group pilot number.
The following are examples of failure conditions that can cause this to occur:
Incomplete digits received in the signaling for the called party.Parent topic: Routing and Translation
Dialed number that is not assigned to a subscriber.
