Chorus phone system upgrade project


This project successfully completed a major upgrade on 5 July 2022 to telephone lines and the supporting infrastructure for these, to provide the University with increased system stability and security.

Key changes

  1. The Chorus Upgrade was completed on 5 July 2022, to improve system stability and security, but not change the features of physical desk phones, voicemail, or other services
  2. Specific features previously used by approximately 1,200 people in Chorus are no longer available in the new version. The relevant people were contacted and moved over to Telephony over Teams in advance of 5 July, with input from IT support staff (ITSS) and telephone coordinators in colleges, departments and elsewhere in the University 

Future plans

Over the next few years, we would like to help move everyone to the solution that works best for them, which is likely to be Telephony over Teams for many people, but not all. This work would be covered by future projects, which are dependent on funding. The Chorus Upgrade project will set the foundation for a service that is Microsoft Teams-compatible.

Expand All
