Expected Duration
210 minutes

To integrate VoIP networks into existing voice networks, you must have the skills and knowledge to implement call routing and design an appropriate numbering plan. A scalable numbering plan establishes the baseline for a comprehensive, scalable, and logical dial plan. This course describes call routing principles, discusses attributes of numbering plans for voice networks, addresses the challenges of designing these plans, and identifies the methods of implementing numbering plans.
A dial plan is the central part of any telephony solution and defines how calls are routed and interconnected. A dial plan consists of various components, which can be used in various combinations. This course describes the components of a dial plan and how they are used on Cisco IOS gateways.
There are times when you might need to manipulate the digits of the telephone numbers that come into and go out of your voice gateway. You may need to remove site codes for intersite calls or add area codes and other digits for routing calls through the Public Switched Telephone Network (PSTN). This course covers digit manipulation and digit manipulation tools.


Introducing Call Routing

  • identify the characteristics of a typical numbering plan
  • list the different types of numbering plans
  • match the attributes of a scalable numbering plan to descriptions
  • recognize how to address overlap numbering plans
  • recognize how a gateway implements the numbering plan
  • identify the principles of gateway call routing
  • Understanding Dial Plans

  • identify the characteristics and components of a typical dial plan
  • recognize the concept of endpoint addressing, including overlapping directory numbers
  • identify the characteristics of call routing and path selection
  • match PSTN dial plan requirements to descriptions
  • identify special ISDN dial plan requirements
  • distinguish between calling privileges and call coverage on a voice gateway
  • Describing Digit Manipulation

  • recognize how a gateway collects, processes, and consumes digits
  • match the digit stripping, digit forwarding, digit prefixing, number expansion, and calling line ID (CLID) commands with their descriptions
  • identify how to implement voice translation rules on a gateway
  • contrast the dialplan-pattern command to the voice translation profiles
  • recognize how to test and monitor digit manipulation on a gateway
  • manipulate the calling number in outbound PSTN calls
