To add a ring group from the 3CX Management Console:
Select “Ring Groups” in the navigation menu.
Click “Add Ring Group”
Define the Ring Group Options:
Name – the name for the ring group.
Virtual Extension Number – accept the default or specify a different one.
Ring Strategy – select the appropriate ring strategy for this ring group,
– Prioritized Hunt – ring the first extension, then the second, etc.
– Ring All – ring all phones at the same time.
Ring time – the time the phones should ring for.
Group Members– add the extensions that belong to this ring group, moving them up or down to prioritize.
Direct Inbound Dialing– optionally assign a DID number to the ring group.
Destination if no answer– set the action to perform if the call is not answered by the ring group.
Click on “OK” to save the ring group.
Note: Unlike a Call Queue, a Ring Group predetermines the available internal extensions and hunts for those, disregarding any extension(s) that become available during the ring cycle.
