About office telephone equipment at IU

On this page:

Before you begin

Teams Calls provides office telephone service for faculty and staff at Indiana University.

For more, see About Microsoft Teams Calls at IU.

For most individual employee phone lines, UITS recommends audio devices that depend on a computer, namely:

  • Headsets: USB headsets provide ease of use and the greatest number of feature options. Many models of USB headset work well with Microsoft Teams Calls.
  • USB speakerphones: In private work settings or conference rooms, USB speakerphone models will work well for those who desire a phone.
  • USB phones: Where a telephone is desired for an individual employee in an open office environment, a USB phone may be appropriate.
  • Internal computer audio devices: In some private work settings, faculty or staff may prefer to simply use a laptop's internal speaker and microphone for calls or meetings.

Some shared phone situations, such as front desks, common areas, labs, classrooms, and conference rooms without a computer, require IP phones, which connect directly to a wired network jack and will not require you to be logged into a computer. Older IP phone models (see below) no longer work. Replace these with a device that is compatible with or certified for Microsoft Teams, whether they are being used in a shared phone situation or at an individual's desk.


If your department plans to take payment card transactions, contact the Office of the Treasurer for guidance.

Obtain audio equipment from UITS

For the best user experience, UITS recommends USB devices and headsets whenever possible, but all equipment below (including the IP desk phones) will work with Teams Calls.

Departmental purchase of equipment

UITS encourages departments to purchase audio equipment through the process listed above.

Many different headset models will work, but IP phones may be incompatible unless they are designed to work with Teams Calls. For assistance in choosing equipment, use the UITS Telecommunications Request form to contact UITS Communications Planning and Implementation.

UITS does not provide webcams; departments that want to provide them for employees can order them as described below.
