This interactive "feature teacher" includes several phone models. Your phone is a 6920. 

This walks through the use of the conference phones but it also includes some content that doesn't apply to us. Please ignore the video conferencing portion. This feature can be added at any time but doubles the cost of the phone.

The phone system comes with a web-based tool.

Please note: we have limited access to this tool and will need to work out ways to reserve it. We'll address the number of licenses we own after the phone system has been up and running.
