Extension Programming
Extension Programming allows extension users and system operators to customize their extensions to meet personal needs. Multiline telephone users can assign a wide range of features to buttons on the telephone. Many other settings (Call Waiting, for example) that do not require button assignment can be programmed on both multiline telephones and single-line telephones.
Users can program their extensions by dialing programming codes or, on 4412D+, 4424D+, 4424LD+, or MLX display telephones, by selecting features from the display. When an extension user programs his or her extension, the system considers the extension busy; therefore, no incoming calls arrive at the extension until programming is completed. See General Feature Use and Telephone Programming for instructions on how to program features on 4400-Series, MLX, ETR, MLS, and single-line telephones.

Before you begin to program a feature onto a button that already has a feature assigned to it, make sure that any light associated with the button is off. In some cases, if the light is on, the feature remains active, even though a new feature has been programmed onto the button. If this happens, you can turn off the original feature only by programming a new button with that feature and deactivating the feature with that button. You can then delete the new feature. |
