Trunk Group Routing - NEC SL1000 Features And Specifications Manual

SL1000
Description
Trunk Group Routing sets outbound call routing options for users that dial the Trunk Group Routing
code (9) for trunk calls. Trunk Group Routing routes calls in the order specified by system program-
ming. If a user dials 9 and all trunks in the first group are busy, the system may route the call to
another group. When you are setting up your system, Trunk Group Routing helps you minimize the
expense of toll calls. For example, if your system has outbound line groups, use Trunk Group Routing
to route calls to the cheapest lines first.
