Cisco VoIP Telephones

Important information about VoIP telephone service

  • Before moving a phone to another office or building, please notify IT Services via the Order IT site so we can update your E911 location information.
  • In the event of a power outage, telephone and network service in most locations should be available for approximately 20 minutes via a UPS (uninterruptible power source). It is important to know the location of an analog phone (also know as "plain old telephone service") for use in an emergency; consult your Department IT Contact if you're not sure where to find one. Depending upon the extent of the emergency, e.g., a major earthquake, cellular service may also be unavailable.


The Cisco VoIP phone transmits calls over the same data network that your computer uses. Combining voice and data over the same network means that you have more control over your phone and its features.

Cisco technology adds the ability to associate your primary telephone number with your login ID, password, and associated profile preferences. Because your profile is associated with your login, you can log in to any Cisco phone within your call group and place or receive calls on that phone as if it were your own.


  • Receive calls from any Extension Mobility (EM) phone with a simple login
