Final forwarding to a voic number or IVR when the call is not answered is important to ensure call coverage. Translation patterns, external phone number masks, calling- party transformations, access codes, DDIs, and route filters enable a variety of important functions in a dial plan, from changing the calling- and called-party number to enabling transparent calling routing over the IP WAN or PSTN and blocking 900 area code numbers. Partitions and calling search spaces enable calling permissions. Time-of-day routing adds additional granularity.
