Setting up the VoIP schedule
Once you have configured the routing and destination codes, ensure that the Routing Service
schedule allows fallback (Overflow) and allows you to activate the service from a control set. You
will note that the Routing Service does not have a Normal schedule. This is because the Normal
schedule is the schedule that runs when no routing services are active.
Follow these steps to set up the VoIP schedule for routing services:
1 Rename Schedule 4 to VoIP (Services, Telephony Services, Scheduled Services, Common
Settings, Schedule Names). Refer to the Programming Operations Guide for detailed
instructions about renaming schedules, if required.
2 Open Services, Telephony Services, Scheduled Services, Routing Service, and click VoIP.
The VoIP schedule screen appears in the right frame.
3 Change the Service setting to Manual.
4 Change the Overflow setting to Y.
Activating the VoIP schedule for fallback
Before activating the VoIP schedule, calls using the destination code are routed over the PSTN.
This is because the system is set to use the Normal schedule, which routes the call over the PSTN.
Once the VoIP schedule is activated, calls made with the VoIP destination code are routed over the
VoIP trunk.
The VoIP line must be activated from the control set for the VoIP trunk, which is specified when
the trunk is created (Services, Telephony Services, Lines, VoIP lines, Enabled VoIP lines, Line
XXX, General). For information about control sets and configuring VoIP line records, refer to the
Programming Operations Guide.
Activating the VoIP schedule:
1 Dial FEATURE 873 from the control set for the VoIP trunk.
The phone prompts you for a password.
2 Type the password.
3 Press
OK.
The first schedule appears.
4 Scroll down the list until VoIP is selected.
5 Press
OK.
The VoIP schedule stays active, even after a system reboot, and can only be manually
deactivated.
