Telephone System Features are functions that parallel, complement, or match existing telephone features. System features relay on software support or existing phone modules to provide the additional functionality. 

Telephone System features are easy to use and in most cases provide faster access to functions. 

To use most of these features you simply enter a dial code on your phone followed by certain numbers (if needed).

The articles in this folder lists the most useful features. They work the same for all Yealink phones, regardless of model. 

Please note that some features may require initial setup.
