Configuring Advanced Dial Plans
Although a Cisco Unified Communications Manager (UCM) server can perform digit
manipulation, perform path selection, and enforce calling privileges (for example, through
the use of partitions and calling search spaces), voice-enabled Cisco IOS gateways can
perform similar functions. In fact, IOS gateways have even more granular control of call
routing, as compared to UCM (for example, being able to route based on caller ID information).
This chapter demonstrates a variety of approaches to manipulate numbers on
IOS gateways. Additionally, path selection is discussed, and you will learn how the Class
of Restriction (COR) feature can be used to implement calling restrictions on dial peers.
