Routing service
Routing service allows you to assign alternate routes to calls. You can take advantage of lower
costs available on selected routes for some days and at some times. You can also use this service to
set up overflow routing, to allow calls that come into line pools that have no available lines to be
answered through an alternate line pool. IP telephones use this service to route calls over a ground
line if the VoIP trunk signal is not strong enough to support a call.
Both the normal and alternate routes are programmed by your installer. Refer to the Programming
and Operations Guide and the IP Telephony Installation Guide for information about overflow call
routing.
Defining services activation mode
Three programming settings: Manual, Automatic and Off, control how the system uses the
different services and their schedules. These settings are specified through the Unified Manager
programming by your installer or system administrator.
• Manual allows you to turn the service on and off at any time from a control telephone using a
feature code.
For example: You may have a restriction service Night schedule that prevents callers from
making long distance calls. Since the Manual setting does not recognize any timing schedules,
you can turn this service on at any time and it will be in effect immediately. To allow long
distance calls, you would turn this service off at the control set, or specify a different schedule
that contains a different set of restrictions.
• Automatic allows you to use the pre-assigned stop and start time for a service. You can enable
and cancel the service by entering the appropriate feature code at a control telephone. If you
select this setting, you use the start and stop times programmed by your installer.
For example: If you want your evening calls to be routed through a different carrier, you can
create the timing for this on one of the spare schedules. You would then find the same schedule
under Routing Service and set it to automatic. When you turn Routing Service on, and choose
this schedule, the telephone will automatically route all calls through the alternate carrier for
the times specified.
• Off prevents the service from being activated.
For more information about programming service schedules and setting up schedule times using
Unified Manager, see the Business Communications Manager Programming Operations Guide.
Note: VoIP lines and PRI lines are automatically set to auto-answer and, therefore,
require target lines. BRI lines that are set to auto-answer also ring at target lines.
Therefore, by specifying target lines in a ring group, all auto-answer lines can be
forwarded to the telephone(s) indicated.
