Telephony Services Application Programming Interface.
An application programming interface that allows computer
telephony applications to be used. TSAPI is supported by
the MERLIN LEGEND Communications System Release
5.0. See also TAPI and CTI.
(touch-tone receiver) Device used to decode DTMF
touch-tones dialed from single-line or Remote Access
telephones.
(Uniform Dial Plan) Composed of the local dial plan and
non-local dial plan . A dial plan that allows a caller at any
extension in a private network to dial the 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.
The 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, it is ambiguous, because a system routes as
soon as it matches the digits sent for a call with the digits in
a local plan or in a non-local dial plan extension range.
When a caller dials
Extension 441 immediately, without considering the last
dialed digit.
