DNIS
Last modified: Monday, May 05, 2003
Short for dialed number identification service, a telephone service that identifies for the receiver what telephone number was dialed by the caller. A common use for this type of system is 800 and 900 phone numbers that often channel multiple phone numbers into the same PBX system. Once the call enters the PBX system, the DNIS will identify which number was dialed and record that information.
