Direct Inward Dialing
Direct Inward Dialing is a trunking arrangement that allows an incoming call from the switched network to reach a specific PBX station directly, without an attendant's assistance.
A customer with a PBX does not need a dedicated line for every employee. Employees can have a unique telephone number and use a pooled trunk group for incoming and outgoing calls. It saves time and reduces cost.
A smarter system
Calls go directly to the right people
Fewer attendants and attendant stations are required
Hold time is reduced and incoming traffic can be handled more efficiently
Individuals can conveniently receive after-hours calls
DID may be provided where Central Office facilities are available and the PBX system or customer-provided switching equipment capabilities permit. DID is available in all Central Offices in the states of AZ, CO, IA, ID, MN, MT, ND, NE, NM, OR, SD, UT, WA and WY.
