Direct Inward Dialing (DID)
Direct Inward Dialing (DID) lets outside callers directly dial a system extension. DID
saves time for callers who know the extension number they want to reach. To place a
DID call, the outside caller dials the local exchange (NNX) and additional digits to ring
the telephone system extension. For example, DID number 926-5400 can directly dial
extension 400. The caller does not have to rely on attendant or secretary call
screening to complete the call.
.
In addition to direct dialing of system extensions, DID provides:
There are 20 DID Translation tables that can be divided between 2000 entries.
Direct Inward Line (DIL)
A Direct Inward Line (DIL) is a trunk that rings an extension, virtual extension or
Department Group directly. Since DILs only ring one extension or group (i.e., the DIL
destination), employees always know which calls are for them. For example, a
company operator can have a Direct Inward Line for International Sales Information.
When outside callers dial the DIL telephone number, the call rings the operator on the
International Sales line key. The DIL does not ring other extensions.
There are 200 available trunks, 64 Department Groups, 256 extensions and 256
Virtual Extensions.
