Customer Controlled Routing (CCR)

CCR is a product that enables you to control and route Automatic Call Distribution (ACD) calls entering your Meridian 1 system. You can provide specific recorded announcements, music, and so on before assigning a call to an agent.

Direct Inward Dialing (DID)

An attribute of a trunk. The central office passes the extension number of the called party over a DID trunk to the PBX when offering a call to the PBX. The PBX is then able to automatically route the call to the extension without requiring operator/attendant assistance. In this way, a single trunk can terminate calls for many different extensions (but not simultaneously).

directory number (DN)

The number that identifies a telephone set on a PBX or in the public network. It is the number that a caller dials in order to establish a connection to the addressed party. The DN could be a local PBX extension (local DN), a public network telephone number, or an ACD DN, the pilot or group number for an ACD queue.

Directory Number Identification Service (DNIS)

A service provided on a trunk. DNIS identifies to the called system the last digits of the number actually dialed by the caller. Meridian Link Release 5C and CCR Release 3C, in conjunction with X11 Release 24, support from seven to 31 DNIS digits. The DNIS digits are sent as in-bank DTMF tones on non-ISDN trunks, or using dial pulses on dial pulse (DIP) trunks. On ISDN PRA trunks, DNIS is carried in the called party IE field of the Q.931 Setup message.
