You can use any directory contact to make a call.
You can also use the directory to select a contact anytime the Dir soft key is displayed in the function’s menus. In that case, the system automatically only shows the types of contacts supported for the function.
All - All directory entries.
Personal - Your own personal directory entries.
External - Directory entries stored by the telephone system for all users to use.
Users - The names and numbers of other users on the telephone system.
Groups - The names and numbers of hunt groups on the telephone system.
Pressing a key enters all of the characters represented by that key. Pressing another key adds the characters from that button to the previous key press.
For example, dialing 527 matches all names starting with JAS (for example "Jason") and with KAR (for example "Karl") plus any other letter combinations from those 3 key presses. See How the Directory Search Works.
To remove all the characters entered so far, press Clear.
