Chorus Infrastructure Upgrade


Chorus, the university-wide telephony solution, was introduced in 2016 and the Chorus team in IT Services support over 15,000 physical handsets, along with software-phone (softphone) clients for end users and service desk colleagues.

The Chorus Upgrade project was commissioned to upgrade the system to the latest version (OpenScape v10), to maintain in-life support and provide access to new features and enhancements for physical telephone handsets, voicemail, analogue services and contact centre functionality. 

At the same time as the upgrade, the University will move all softphone users and some Web client users (who select a preferred device) over to Telephony over Teams. These Teams users will be able to make and receive external and internal calls using telephone numbers from within Teams, using a headset rather than a physical telephone handset. Unless a change is requested, all existing telephone numbers will remain the same. 

Contact centre users and Web client users who are not selecting a preferred device will continue to use the existing functionality, which will be upgraded. 

Key Benefits

  • An upgrade to the latest version (OpenScape v10)
  • Prolong the working life of existing physical phones
  • Moving to an enhanced virtual infrastructure, to provide increased stability and flexibility 
  • Replacement of end-of-life dedicated network hardware
  • Makes further use of MS Teams functionality, which has been well adopted for calls, collaboration, meetings and internal communications
  • A new strategic access management tool, allowing secure, managed, remote access for third party support engineers


The upgrade is due to be completed in Trinity Term 2022.
