Cisco Voice over IP

This course is intended for System Engineers and Channel Partners/Resellers.

• Identify the components, processes, and features of traditional telephony networks that provide end-to-end call functionality
• Describe two methods of call control used on voice and data networks and provide one example of a protocol for each
• List at least five components or capabilities that are required to provide integrated voice and data services in campus LAN, enterprise, and service provider environmentsSelect the appropriate analog voice connection to a Cisco device given the types of analog connections and their susceptibility to line quality problems

• Choose a voice compression scheme that best suits your needs given the fundamentals of digital voice encoding
• Describe the appropriate signalling method to deploy in a telephony system given the type of signalling: between PBXs; between PBXs and central offices; or specialized, such as ISDN
