Considerations

DGC groups are particularly useful when the answering group receives a high volume of calls. Call completion time is minimized and attendant assistance is not required.

Any number of outside trunks may be administered to feed into a DGC group. A trunk may feed only one DGC group.

Interactions

●Attendant Camp-On:For V1 systems only: if the attendant attempts to camp-on a

second call to a DGC group, it is immediately returned on the console.

●Attendant Direct Extension Selection: When all stations in a DGC group are

busy, the status LED on the Selector Console lights steadily.

●Call Coverage: When a call rings at DGC station that has Call Coverage, the call will receive that station’s coverage. Calls directed to a busy DGC group do not receive call coverage. Instead, after a predefined number of rings, the call will be

transferred	to a delay	announcement	(if provided), or	ringing will	be transferred to
all button	appearances	of the line and	the SLAC queue	(if trunk has	ringing enabled;
V2).

●Call Pickup: A DGC group member can also be a member of a Call Pickup group.

●Direct Group Calling Delay Announcement: Provides a recorded announcement

to an outside caller who has been placed in queue for a DGC group.

●Direct Inward Dialing: An incoming DID call may match a DGC group access code.

●Direct Station Selection (DSS): A DSS button can be assigned to a DGC group.

The associated LED lights steadily when all stations in the group are busy.

●Modem Pooling: Modem Pooling supports calls to data endpoints that are part of a DGC group. While an incoming data call is in a DGC group queue, the caller receives ringing. The conversion resource is inserted if the call is completed to a digital endpoint.

●Personal Lines: An outside line directed to a DGC group can be assigned button

appearances in addition to the DGC group assignment. When an incoming call is ringing at a DGC group, the status LED on the voice terminal button appearance lights steadily, indicating that the line is busy. If the call goes unanswered for a pre-determined number of rings (and no delay announcement is provided), ringing will be transferred to all button appearances of the line and the status LED will flash.

●Station Message Detail Recording (SMDR): For an incoming call to a DGC group that was connected to an announcement but was never answered, “O” will be reported in the “STN” field of the call record. If the call was answered by a station

after receiving the announcement, that station will be listed in the “STN” field.

●Tie Trunks: Calls to a busy DGC group via auto-in tie trunks will be queued, but will not receive a delay announcement. Calls to a busy DGC group via dial-in tie trunks will not be queued; these callers will receive Busy Tone.
