Section 3: FeaturesProduct Description 1213Trunk Group RoutingDescriptionTrunk Group Routing sets outbound call routing options for users that dial the Trunk Group Rout-ing code (9) for trunk calls. Trunk Group Routing routes calls in the order specified by system pro-gramming. If a user dials 9 and all trunks in the first group are busy, the system may route the call toanother group. When you’re setting up your system, Trunk Group Routing will help you minimizethe expense of toll calls. For example, if your system has outbound WATS lines, OCC lines andDDD lines, use Trunk Group Routing to route calls to the WATS lines first.Trunk GroupsDescriptionTrunk Groups let you optimize trunk usage for incoming and outgoing calls. With Trunk Groups,users can have loop (rotary) keys for trunk calls. Incoming trunk group calls ring these loop keys.For outgoing calls, the user presses a loop key to access the first available trunk within the group.You set the access order in trunk group programming. The system allows up to 100 trunk groups.Loop keys give an extension user more available function keys, since the user doesn’t need a sepa-rate line key for each trunk. The user only needs one loop key for each trunk group. This simplifiesplacing and answering calls.Aspire• Available- 100 trunk groups and 100 routes.Aspire• Available - 100 trunk groups.OCCModeratelyExpensiveWATSLeast ExpensiveDDDMost ExpensiveThird ChoiceSecond ChoiceFirst ChoiceOutbound CallRoute 1 Route2 Route 3
