Inside Macintosh: Telephony /

Chapter 3 - Directory Numbers

This chapter describes directory numbers, named reference points that are used to initiate or receive calls on a telephone terminal. For example, the number (408) 555-1212 is a directory number. A directory number is essentially just a telephone number.

To use this chapter, you should already be familiar with the information presented in the chapter "Introduction to Telephony on the Macintosh" earlier in this book. You should also be familiar with the information in the chapter "Telephone Terminals." A directory number is always associated with exactly one telephone terminal.

This chapter describes the data structures and functions you can use to manage directory numbers. See the chapter "Telephone Manager Messages" for a description of the directory number messages that the Telephone Manager can send to your application. See the chapter "Telephone Tools" for a description of the directory number messages a tool can send to the Telephone Manager.
