A line can be configured to present its incoming calls to one of the 6 hunt groups (rotary) or 4 calling groups (ring all).
Rotary Ringing
This mode of ringing is used by the 6 Hunt Groups. The groups can be rung directly or used as the coverage destination for incoming calls on trunks and trunk channels.
A call to a hunt group first alerts the first available member (not on another call) of the group after the one who last answered a group call. If after approximately 15 seconds the call has not been answered, it changes to alerting the next available member of the hunt group in extension number order. When alerting the currently targeted member of the group:
•If the user does not have a line appearance for the line, it alerts on an intercom or call appearance button.
•If the user has a line appearance for the line, the call alerts on the line appearance button with the standard indication of a ringing call for me (slow green flash). The line's ringing options are overridden and the line always rings immediately.
•Any other users, including other group members, with the same line appearance will see the line button indicate a ringing call but not for me (slow red flash).
•A call targeted to a group does not go to voicemail. Instead it will alert the group until answered or abandoned.
•Any extension in the system can answer the call using the line appearance of the line or using one of the pickup features (active line pickup, call pickup, group call pickup).
If the currently targeted user has forwarding to another extension set, the call is forwarded. Forwarding to an external number is not used, the call will alert the original extension instead.
If coverage is active at the targeted hunt group extension, it is not followed and alerts the normal number of rings before hunting on to the next hunt group extension.
Ring All
This mode of ring is used by the 4 Calling Groups and the Operator Group. The groups can be rung directly or used as the coverage destination for incoming calls on trunks and trunk channels.
A call to the hunt group alerts all members who are idle (not on another call). The call alerts in the same way as for a rotary group but does not hunt if not answered after 15 seconds, instead it continues to alert the same members until answered.
