Ring Groups
Ring groups allow a group of phones, or devices, to ring simultaneously
or in sequence (ring order). This provides the opportunity for multiple
people to answer a call (ring all) or one person can answer a call from any
phone. The Asterisk Appliance 50 does not come with a default ring
group. To create a new ring group click New Ring Group at the top of the
Ring Groups page.

Note: You need at least one member to be able to define a ring group.
You will not be able to define a ring group without any user
extensions.
