Availability and service charges for external Caller ID in your area may

Calling Groups — These allow incoming calls to be simultaneously
directed to a particular group of telephones. This means the call is more
likely to be answered and also means that calls can be directed to a group

Hunt Groups — Hunt groups allow you to establish informal “call
centers” which ensure that calls are never missed. Calls ring to one
member of the group. If there is no answer, the call rings to the next
