Telephone Services for Stanford Health Care and Stanford Children’s Health

University IT (UIT) offers Cisco VoIP (Voice over Internet Protocol) for Stanford Health Care (SHC) and Stanford Children’s Health (SCH) departments requiring telephone service. VoIP technology offers a variety of advanced features and gives you the freedom to move your phone from one office to another within the same building without having to place a service call.

Important information about VoIP telephone service:

  • Before moving a phone to another office or building, please notify UIT via the Order IT website so we can update your emergency 911 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.


Cisco VoIP 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
  • Up to three calls per line, with a fourth reserved for conferencing and transferring
  • Set up six-way audio conferencing from your phone
  • Look up directory services from your phone
  • Look up, manage, and create directories via a web user portal
  • Remotely call-forward your phone number
  • Ring a primary phone number and up to two remote destinations

Note: VoIP phones plug into a network port instead of a phone port. There is a simple login procedure at initial setup for Extension Mobility (EM) phones. Most phones in common areas are static and do not require login. See How to Use Your Phone Equipment for instructions.
