The telephone has a built-in directory where you can create contact entries with their names and phone numbers. Please consult the user guide for your particular model of telephone for detailed instructions on how to create and search for directory entries. The procedure varies between models.
The hosted telephone switchboard also has a feature to maintain a company-wide directory of contact names & numbers which is then propagated automatically to each telephone. The shareable directory feature must be enabled by your Solution Provider and it requires some changes to the configuration of your telephones. Please contact your Solution Provider if you would like to set up this feature.
When you have created entries in the built-in directory then you can open the directory menu on the telephone and search for the contact name just as you would on a mobile phone. When you have found the correct entry then press the Call key.
When you receive a call from someone who is named in the directory then their name will be displayed on the telephone screen instead of their telephone numer.
