Voice over IP (VoIP) is a communication technology that allows telephone calls to be placed using a broadband network instead of a regular analog phone line.

Telephone Models

Four models of VoIP desktop phones are available for use on campus:

• Cisco IP Phone 7811s – VoIP phone with High resolution, graphical grayscale display for easier viewing. More Information.
• Cisco IP Phone 7945 – Standard office VoIP phone on campus
• Cisco IP Phone 7965 – VoIP phone with six programmable buttons

• Cisco IP Phone 7841 – VoiP phone with 4 programmable buttons
• Cisco IP Phone 8841 – VoiP phone with 8 programmable buttons

The 7965 and 7975 can both accept an optional sidecar which contains twelve additional buttons, and each sidecar allows for two “pages” of buttons. In effect, one sidecar can store a total of twenty-four phone numbers.

For assistance with programmable buttons on the 7965 and 7975 models, contact the Technology Support Center by submitting a Ticket, by phone (309) 438-4357 or by email at SupportCenter@IllinoisState.edu.
