Using Feature Codes
General Instructions
For those features that require you to dial a feature code, this section provides general instructions.
In general, you dial # and a feature code to access a feature. and # ✱ and the same feature code to cancel the feature. Chapter 5 describes each feature and how to use it; Appendix B provides a summary of features and feature codes.
N o t e:
To use # to access features, you must not be on an outside line — that is, you must be listening to the system’s dial tone, not the telephone company’s dial tone.
