UDP
Uniform Dial
dial plan that allows a caller at any
same number of digits to reach any other extension in the private network, even if
the originating extension is physically connected to one communications system
and the terminating extension is physically connected to a different
communications system.
Unambiguous Numbering
Practice of numbering of extension ranges, remote access codes, or other
system components to avoid routing conflicts in network or local calling. For
example, Extension 441 is unique when compared to Extension 4410; however,
this is ambiguous, because the system routes as soon as it matches the digits
sent for a call with the digits in a
extension range. When a caller dials 4410 , therefore, the system routes the call
to Extension 441 without considering the last dialed digit.
