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.
Voice over IP (VoIP) is one type of telephone service available in campus offices, classrooms, and other areas at Illinois State University.
Four models of desktop VoIP phones are available for use on campus:
- Cisco IP Phone 7911 – A basic VoIP phone with a small screen
- Cisco IP Phone 7945 – Standard office VoIP phone on campus
- Cisco IP Phone 7965 – VoIP phone with six programmable buttons
- Cisco IP Phone 7975 – VoIP phone with eight programmable buttons and a touch screen
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 Telecommunication & Networking.
