Use the Time Ranges page to create, modify, delete, and manage time ranges for each administered Routing Policy.

You must specify as many Time Ranges as necessary to cover all hours and days in a week for each administered Routing Policy. For example:

• Routing Policy A can be in effect on all weekdays from 9:00 a.m. to 5:59 p.m.

• Routing Policy B can be in effect on all weekdays from 6:00 p.m. to 9 a.m.

• Routing Policy C time ranges can be in effect on weekends.

These three Time Ranges together determine how calls should be routed throughout the week.

Routing Policies that a Session Manager server selects can be prioritized based on time-of-day routing information. Based on this selection, Session Manager:

• determines the current time at the destination entity. The current time on the Session Manager is converted to the time at the destination SIP Entity using the administered time zone.

• finds the Time Range that you administered. The Time Range contains the time at the destination.

• finds the rank that you administered on the Routing Policy for the selected Time Range.

After the selection, Session Manager orders the Routing Policies in ascending order and tries one route in each priority as per the administered order.
