With the Sharing Mapping among Communication Manager PBXs feature, you can share the station name and station mapping information among multiple Communication Manager using SIP subscriptions. Extension to Cellular users can be recognized on another PBX where they are not administered. When the foreign Communication Manager acquires the shared information, it creates a temporary mapping to associate the shared cell phone number with the shared extension and the station name. Any calls with a calling number matching a temporary mapping can use the shared station name and extension for incoming call displays.
