Direct Inward Dialing (DID) 2 - 327
When ordering DID service, provide the Telco with the following information:
Conditions

Analog DID requires installation of a DID(4)-U10 ETU (provides four DID ports). Depending
on programming, the system may assign both trunk and extension ports (if OPX is selected
in Program 10-03-01) when this ETU is installed.

DID service must be purchased from your local telephone company.

DID Intercept for each DID number works for DID trunks with a trunk service type 3 in
Program 22-02. Other trunks may use the DID table, but the DID intercept feature for each
DID number is not yet supported.

T1 or PRI DID requires a DTI-U40 ETU.

When a call is transferred because of Call Forwarding No Answer, Call Forwarding Busy, or
DND, the reason for Transfer option can display to the transferred extension when the call
is ringing to their telephone.

Direct Inward Lines (DILs) also allow outside callers to dial a system extension, virtual
extension, or Department Group directly.

DISA also allows outside callers to dial a system extension directly.

The Off-Hook Signaling provide DID calls with signaling options. Refer to Off-Hook
Signaling for specific details.

DID trunks do not ring external page speakers. Only trunks defined as normal in Program
22-02-01 ring external page speakers.

To simplify answering DID calls, assign function keys as line keys for the DID trunks.

SMDR can print trunk port names or received dialed number for ANI/DNIS or DID trunks. If
enabled, DNIS digits can be printed on the SMDR reports instead of the trunk name.

Transferred calls on DISA, DID, DIL, ISDN trunks, or from the VRS can display the reason
a call is being transferred (Call Forward, Busy, No Answer, or DND).

When defining trunks as DID or DID Mode in PRG 22-02-01, DID translation (PRG 22-11 or
PRG 22-17) must be used, even if the incoming digits match the extension number.
