Cisco CVOICE 8.0: Path Selection and Calling Privileges

This course is included in our On-demand training solution.


Path selection is one of the most important aspects of a well-designed VoIP system. High availability is desirable so that there is usually more than one path for a call to take to its final destination. Multiple paths provide several benefits, including redundancy in case of a link failure or insufficient resources on that link and a reduction in toll costs of a call. This course introduces the path selection strategies and methods to implement them.
Calling privileges on Cisco IOS gateways are dial plan components that define the types of calls that a phone, or group of phones, is able to place. This course describes the concept of calling privileges and how they can be implemented on Cisco IOS gateways using class of restriction (COR).
