Dialed Number Identification Service

DNIS Recognition Telephony Applications

dnis software Database Systems Corp. provides computer telephony integration technology to the call center industry. DSC offers CTI Software and phone systems as well as outsourcing call center services that employ telephony technology.

Inbound phone calls are processed using our ACD Software and interactive voice response (IVR) that answers calls without an operator.

One of the many criteria and variables that this software uses in routing phone calls is the phone number that was dialed by the caller. This number (or service) is referred to as DNIS.

What Is DNIS?

    DNIS (Dialed Number Identification Service) is a telephone service that identifies for the receiver of a call the number that the caller dialed. It's a common feature of 800 and 900 lines. If you have multiple 800 or 900 numbers that are answered by the same phone system, DNIS tells the controlling program on this system which number was dialed.

    DNIS works by passing the touch tone digits or DTMF (dual tone multi frequency) to the processing unit where a special facility can read and display them or make them available to the call processing application.

DNIS Applications

DSC software utilizes DNIS in several of our computer telephony software applications.

ACD and DNIS Routing

ACD systems employ DNIS as the primary call routing mechanism. Calls are processed using our automatic call distribution system which determines the called number and transfers this call to an agent hunt group.

Call center agents or workstations are identifed to the phone system and placed in various user groups. As a call is received, the DNIS of this call is used to lookup the agent group associated with this DNIS. The next available agent in this group is determined and the call is routed to this workstation.

IVR and DNIS Processing

IVR Software utilizes DNIS in several ways. First, IVR programs are initially invoked based upon the call's DNIS. Thus, a specific IVR program can be assigned to each identified phone number routed to a phone system.

Once the IVR program has been invoked, it in turn can query the phone system to determine the number dialed. This is important when multiple phone numbers route to the same IVR program.
