Introduction to Telephony

In order to be considered successful, IP telephony applications must be indistinguishable, in all important respects, from "regular" telephony.

Before you can engineer this kind of smooth transition, you must understand what you're replacing, so that you can be sure that you meet user expectations. That is the subject of this Study Guide -- how the telephone system works, what users expect of it in terms of performance, and how it operates. If you understand these things, you are much less likely to disappoint your users when you migrate to an IP telephony network. You'll also be much better prepared to understand and solve telephony-related problems you encounter on Cisco certification exams.
