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.
NOTE
In addition to direct dialing of system extensions, DID provides:

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 400 available trunks, 64 Department Groups, 960 extensions and 512
virtual extensions.
DIL Delayed Ringing
Extensions in a Ring Group can have delayed ringing for another extension DIL. If
the DIL is not answered at its original destination, it rings the DIL No Answer Ring
Group. This could help a Technical Service department, for example, that covers
calls for an Inside Sales department. If the Inside Sales calls are not answered, they
ring to the Technical Service department.
Direct Inward System Access (DISA)
DISA permits outside callers to directly dial system extensions, trunks and selected
features. This could help an employee away from the office that wants to directly dial
co-workers or use the company trunks for long distance calls.
