Vacant Intercept

If a caller misdials or dials an extension that does not exist, or there is a DID Translation Table error,
Vacant Intercept handles the call routing. Vacant Intercept is always enabled. Since Line Over

ow is dis-

abled by default, Vacant Intercept by default routes to Key Ring (and cannot over

ow).

- If the telco doesn’t send any digits into the system, or

If the digits sent by the telco don’t correspond to a DID Translation Table entry, or
If the destination extension is out of service:
The call follows the

3112-Termination

routing for the line. This includes the settings for Day Ter-

mination, Day Over

ow, Night Termination, and Night Over

ow. The call is handled the same as

an analog line and follows the normal system timers.

- If the digits sent by the telco have a DID Translation Table entry with no corresponding destination

programmed:
No routing occurs and the caller hears busy tone.

❥

DID Camp-On

DID Camp-On sets what happens to DID calls to busy extensions when you have Busy/DND Intercept
disabled. With DID Camp-On enabled, a call to a busy extension camps-on to the extension. Without
DID Camp-On, the caller to the busy extension just hears busy tone (or follows the intercept program-
ming if enabled).

By default, DID Camp-On is disabled.

❥

DID Routing to Voice Mail

If a DID call is unanswered and is eventually routed to voice mail, it will route to the mailbox of the ini-
tial DID destination. This is true regardless of whether the call routed to voice mail via DID Line Over-

ow, Call Forwarding, or Extension Hunting.

ANI/DNIS Support

The system is compatible with telco's T1 Automatic Number Identi

cation (ANI) and Dialed Number Infor-

mation Service (DNIS) services. ANI/DNIS services can be provided on T1 loop start, ground start, and DID
lines (but not E&M). ANI/DNIS Compatibility provides:

❥

Selectable Receive Format

You can set up the system for compatibility with any combination of ANI, DNIS and Dialed Number
(Address) data provided by the telco.

❥

Flexible Routing

The system can route the incoming call based on the received DNIS data and the entries stored in the
DID Translation Table.

❥

Caller ID

The system can use the received ANI data to display the caller’s number on the called extension’s dis-
play. The ANI data can be up to 10 digits long. (Note that the T1 PCB can alternately receive normal
FSK-based Caller ID if provided by the telco, but cannot route on that data.)

Direct Inward Line

A Direct Inward Line (DIL) is a line that rings an extension directly. Since DILs only ring one extension,
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’s phone number, the call
rings the operator on the International Sales line key. The DIL does not ring other extensions.

Assigning a DIL to an extension automatically provides immediate ringing and incoming access for the line,
with no additional programming required.

A DIL can ring:

❥

Extension numbers (including the attendant’s extension)

❥

Ring Group master numbers

❥

UCD Group master numbers (including the voice mail master number)

A DIL lets an employee know which calls are just for them.
