Most PBX systems provide a directory search option that allows callers to enter the first few letters of a person's name to determine their extension. As long as a user has a voicemail box, the user will be listed in the directory. FreePBX allows the directory search experience to be customized to taste.
To customize directory search options, click on the General Settings link under the Basic menu on the left as shown in the following screenshot:
Scroll down to the Company Directory section to find the directory search options:
The Find users in the Company Directory by drop-down menu allows searches to be restricted to the user's first name, last name, or both first name and last name.
If Announce Extension is checked, then the extension number of the user being searched for will be played to the caller before the caller is transferred.
The Operator Extension is the extension, external phone number, ring group, or queue number that the caller will be transferred...
