Using Time-of-Day Routing

With the 4.1 release of Cisco CallManager, time-of-day routing routes calls to different locations based on the time of day when a call is made. For example, User A wants to configure the CFA number to an international number. User A can set this number only during the 8:00 a.m.-to-5:00 p.m. time period because outside these hours the system does not find the international number in the partition that is used to validate the CFA number.

Time-of-day routing can be used for other purposes as well. With time-of-day routing, a least-cost routing system can be designed to choose the cheapest provider for a specific time of day. For example, assume that there are two telephony providers, ABC and XYZ. Between 8 a.m. and 1 p.m., provider ABC is the cheaper provider, so Cisco CallManager routes calls over this provider during that period. After 1 p.m., provider XYZ becomes the cheaper provider, so the Cisco CallManager uses this provider then.

A complete description of time-of-day routing and its configuration can be found in Chapter 13, "Implementing Telephony Call Restrictions and Control."
