skype phone number transfer to teams

Hi,

If your number is in Skype for Business you do not have to transfer it, you can move your users to Teams Only and continue using the phone number.

If you are using Skype, it will not be end of life, that consumer edition of Skype will continue. But you can transfer your number.

Depending on what country your number belongs to you might use a wizard.
