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. To use DISA, the
employee:

Dials the telephone number that rings the DISA trunk.

Waits for the DISA trunk to automatically answer with a unique dial tone.

Dials the 6-digit DISA password (access code).

Waits for a second unique dial tone.

Accesses a system trunk, uses a selected feature or dials a system extension.
DISA calls ring system extensions like other outside calls. If an extension has a line
key for the DISA trunk, the call rings that key. If the extension does not have a line
key, the extension must have a Call Appearance (CAP) key to answer the call.
You can set DISA operation differently for each Night Service mode. For example, a
trunk can be a normal trunk during the day and a DISA trunk at night. You can also
set the routing for DISA trunks when the caller dials a busy or unanswered extension,
dials incorrectly, or forgets to dial.
DISA allows 15 users, 15 DISA Classes of Service and 200 trunks.
Enhancements
With Version 3000 or higher system software, if an outside caller dials an invalid
extension number when connected to the VRS Automated Attendant or calling in
on a DISA trunk, the following new options are available to route these calls:

Extension Number (e.g., operator)

F-Route Dial (e.g., outside phone number)
