A group is a collection of users used for a special purpose. For example, a group can be used as the destination for incoming calls on an external trunk.

The system has a fixed set of groups. You cannot add or remove groups. However you can edit the the user membership of all the groups. A user can be a member of several or even all groups.

While call to a group alert at user extensions, they will not go to user voicemail. They will follow user forwarding if set to forward to another extension. They will not follow external forwarding.

The following different types of groups are used:

Calling Group
This type of group can be set as the Coverage Destination of a trunk or trunk channel. It can be also the destination of calls routed using DID call mapping or call-by-call settings. Calling Group 1 is also used by the Simultaneous Page function (*70).

Hunt Group
This type of group can be set as the Coverage Destination of a trunk or trunk channel. It can also be the destination of calls routed using DID call mapping or call-by-call settings.

Night Service Group
When the system is put into night service, this group overrides the Coverage Destination of all trunks.

Operator Group
This option is only available for systems with their Mode set to PBX. By default the group contains the first extension on the system. For PRI and BRI trunks, it is fixed incoming destination for calls unless DID Mapping is applied to the call. It can also be selected as the destination for incoming SIP calls.

Pickup Group
Users can be pickup calls currently alerting any member of a pickup group. They do not need to be a member of the group.
