Direct Inward Line (DIL) 2 - 337
Direct Inward Line (DIL)
Description
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.
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 into the Technical Service department.
Conditions
If unanswered, a DIL without delayed ringing rings an extension until the outside party
hangs up.
If a DIL rings a Department Group and all agents are busy, the system routes the call as
follows:
1. The trunk rings the overflow destination assigned in PRG 22-08.
2. If there is no 22-08 assignment, the call rings according to the Ring Group assignments in
PRG 22-04 and PRG 22-05.
3. If none of the destinations in steps 1~2 above are available, the call continues to ring until a
destination becomes free.
The DIL follows call forwarding programming, even to voice mail.
When a call is transferred by Call Forwarding – No Answer, Call Forwarding – Busy, or
DND, the Reason for Transfer can display at the transferred extension.
You can place DILs in trunk groups to make outgoing DIL calls easier.
A DIL can have an Extension (Department) Group as its destination.
If a DIL destination extension is in DND, an incoming call rings according to Ring Group
programming (PRG 22-08 then PRG 22-05).
If a user puts the telephone in Do Not Disturb, calls routed to the telephone in DND do not
follow call forwarding.
