Configuring routes for fallback
Configuring routes allows you to set up access to the VoIP and the PSTN line pools. These routes
can be assigned to destination codes. The destination codes then are configured into schedules,
where the PSTN line is assigned to the Normal schedule and the VoIP route is assigned to a
schedule that can be activated from a control set.
For details about route and schedule configuration, refer to the information under the headings
below:
• “Adding routes for fallback” on page 114
• “Adding the destination code for the fallback route” on page 116
• “Setting up the VoIP schedule to overflow” on page 118
• “Activating the VoIP schedule for fallback” on page 119
Pre-configuration requirements
• If you have not already done so, remember to define a route for the local PSTN for your own
system so users can still dial local PSTN numbers.
• Ensure the PSTN and VoIP line pools have been configured before you continue with this
section. For information about creating a VoIP line pool, see “Setting up the local gateway” on
page 91. Configure PSTN lines under Services, Telephony Services, Lines, Physical Lines.
Note: If you already have routes for your PSTN or VoIP line pools configured, you do not
need to configure new routes, unless you cannot match the dialed digits.
