Hunt Groups 237If the Total Timeout value exactly matches the sum of the Per-DeviceTimeouts, the behavior of a single incoming call is the same for bothlinear and circular hunt groups.When a second call is routed to a linear or circular hunt group, thetelephone on which the second call first rings is different:■ For Linear Hunt Group, the new call rings on the first telephone in thegroup.■ For a Circular Hunt Group, the new call rings on the telephone that isnext in the ringing sequence.Calling Groups In this special type of hunt group, an incoming call rings on all telephonesin the group simultaneously. After the Total Timeout value is reached, acall 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 oftelephones in a calling group.Call Coverage For each hunt group, you can define where the NBX system routes anunanswered call (the call coverage point):■ Voice Mail — An unanswered call goes to the hunt group extension’svoice mailbox, or to a configured operator.■ Auto Attendant — An unanswered call goes to the AutomatedAttendant that you specify.■ Phone Number — An unanswered call goes to the extension thatyou specify, such as the receptionist, or another hunt group.Hunt GroupSupervisoryMonitoringYou can configure the NBX system to allow a privileged user to join anongoing conversation in a hunt group with or without the knowledge ofthe parties involved in that conversation. This feature is called SupervisoryMonitoring.The monitoring user is called the supervisor. The supervisor, who may ormay not be the system administrator, can join a call between a personcalling into the system (for example, a customer) and a person on-sitewhose job it is to accept incoming calls. Joining calls in progress can helpensure proper customer support.The NBX system does not support Supervisory Monitoring on outgoingcalls.
