Section 700 - Operation

Several types of CO ringing are available for the System including the following:

•

Direct Inward Dialing (DID) Ringing

•

Direct In Line (DIL) Ringing

•

Direct Inward System Access (DISA) Ringing

•

Multiple Ringing

These ringing types may be used in any combination in the System.

DID Ringing allows calls on a common CO to be directed to ring to a specific extension or group of 
extensions, etc. based upon the final digits dialed. These final digits are received from the DID trunk 
and compared to a DID Table that determines where the calls should ring. Depending on the 
assignments in the DID Table, names or trunk numbers are displayed. (Names can be up to 10 digits 
long.)

DID Ringing can be very useful by sending calls directly to a specific extension, hunt group, etc. 
based upon the number dialed. Since a relatively small number of trunks handle the DID calls, this 
can be more cost efficient than DIL trunks or attendant group answering and transfer. (DID may send 
a call to a group using the Virtual Extension feature.) DID Busy/Delayed Ringing is also available 
with DID Ringing. (See “DID Day/Night Busy/Delayed Ringing” on page 3-50.)

Caller ID takes priority over the DID name assignment.

•

Only one of the two DID tables may have name assignments.

•

If the DID/DIL destination is a Directory Number (DN), the call goes to an extension that has a 
destination key even if the Primary Directory Number extension is busy or does not answer.

•

If the DID/DIL destination is an UNA extension, the UNA will ring depending on DID number 
tenant group/ DIL incoming CO tenant group.
