Direct Inward Dialing (DID) 2 - 321
Direct Inward Dialing (DID)
Description
Direct Inward Dialing (DID) lets outside callers directly dial system extensions. DID saves time for callers
who know the extension number they wish 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.
 Direct Inward Dialing requires DID service from Telco.
In addition to direct dialing of system extensions, DID provides:

DID Dialed Number Translation

Flexible DID Service Compatibility

DID Intercept

DID Camp-On
There are 20 DID Translation tables that can be divided between 2000 entries.
DID Dialed Number Translation
DID allows different tables for DID number translation. This gives you more flexibility when buying DID
service from Telco. If you cannot buy the exact block of numbers you need (e.g., 301~556), use the
translation tables to convert the digits received. For example, a translation table could convert digits
501~756 to extension numbers 301~556.
The Electra Elite IPK II system has 2000 DID Translation Table entries that you can allocate among the
20 DID Translation Tables. One translation is made in each entry. For a simple installation, you can put
all 2000 entries in the same table. For more flexibility, you can optionally distribute the 2000 entries
among the 20 tables.
In addition to number conversion, each DID Translation Table entry can have a name assigned to it.
When the DID call rings the destination extension, the programmed name displays.
Enhancements
Version 1500 or higher is required for the DID Call By Time Schedule feature.
