We need your information – preparing for internet phone calls

13 Dec 2022

If you are a UK-based colleague on a Microsoft 365 staff licence, you need to submit your details via our online form, so we can assign you a phone number to make calls via Microsoft Teams Voice

Teams Voice

We are preparing for the national telecoms switchover to internet-based phone calling, when all copper wire landlines will cease to work.

To make this switch we need your individual details, so we can give you access to internet phone calls via Teams Voice. This applies whether you currently have a phone number or not.

All colleagues with a Microsoft 365 staff licence will be given a phone number and you will be able to make external calls through Teams on your laptop, desktop, smartphone, or other device. Internal calls can continue to be made via Teams-to-Teams video calls.

What do I need to do next?

Recently you will have received an email containing our online form. If you have not done so already, please submit your details via the form below by 5pm on Friday, 16 December.

Some of this data may already have been collected within your department – but this survey asks for some additional key information about your role, so please do complete it. This switchover is being managed by the External Calling (Teams Voice) Project.

What does this change mean for me?

  • If you are based in the UK and have a staff Microsoft 365 licence, your external phone calls will move to Teams Voice.
  • Where possible, you will retain your existing University phone number. If you do not have a University phone number, you will be given one.
  • Please note the roll-out is only making changes in buildings where phone lines are provided by the University.

When will this change happen?

The roll-out will be gradual, based on phone number order and it will begin early in the new year. When we contact you next, it will be via email with an invitation to a live training event and following that you will receive your individual transfer details. In the meantime, you can access our Microsoft 365 training and accessibility resources.
