Calling Groups; Call Coverage; Hunt Group Supervisory Monitoring - 3Com NBX 100 Administrator's Manual

If the Total Timeout value exactly matches the sum of the Per-Device
Timeouts, the behavior of a single incoming call is the same for both
linear and circular hunt groups.
When a second call is routed to a linear or circular hunt group, the
telephone on which the second call first rings is different:

Calling Groups

In this special type of hunt group, an incoming call rings on all telephones
in the group simultaneously. After the Total Timeout value is reached, a
call that is still unanswered is routed to the group's call coverage point.
The value in the Per Device Timeout field has no effect on the behavior of
telephones in a calling group.

Call Coverage

For each hunt group, you can define where the NBX system routes an
unanswered call (the call coverage point):
Hunt Group You can configure the NBX system to allow a privileged user to join an
Supervisory ongoing conversation in a hunt group with or without the knowledge of
Monitoring the parties involved in that conversation. This feature is called Supervisory
Monitoring.
The monitoring user is called the supervisor. The supervisor, who may or
may not be the system administrator, can join a call between a person
calling into the system (for example, a customer) and a person on-site
whose job it is to accept incoming calls. Joining calls in progress can help
ensure proper customer support.
The NBX system does not support Supervisory Monitoring on outgoing
calls.
For Linear Hunt Group, the new call rings on the first telephone in the
group.
For a Circular Hunt Group, the new call rings on the telephone that is
next in the ringing sequence.
Voice Mail — An unanswered call goes to the hunt group extension's
voice mailbox, or to a configured operator.
Auto Attendant — An unanswered call goes to the Automated
Attendant that you specify.
Phone Number — An unanswered call goes to the extension that
you specify, such as the receptionist, or another hunt group.
