Direct Inward Dial PBX Trunks

Connect Incoming Calls Quickly and Cost-Effectively

Allow customers to directly call a specific extension on your PBX system.

Requiring each incoming call to go through an attendant increases cost and delays the response your callers receive. CenturyLink® Direct Inward Dialing (DID) service allows an incoming call from the switched network to reach a specific PBX station directly, without an attendant's assistance. Incoming and outgoing calls are routed through a pooled trunk group, eliminating the need for a dedicated line for each employee while still allowing each employee to have a unique telephone number. Reducing cost while improving service, CenturyLink DID provides a direct connection into your organization for customers, partners, and opportunities of all kinds.

How It Works

CenturyLink Direct Inward Dialing service is available with switching vehicles served by trunk service (trunk side of Central Office). Answer supervision is required from the customer's PBX. Seven-digit local exchange numbers are assigned to each DID station (by PBX programming) from a block of numbers reserved for the customer. When the number is dialed, the serving Central Office directs the call to a dedicated pool of one-way incoming analog DID trunks assigned to that number block. The Central Office then outpulses the last three or four digits (depending on the customer's PBX requirements) to the PBX. The PBX routes the call directly to the called station without going to the attendant.
