    There is a feature in the teams powershell module and the commandlet
    Get-CsPhoneNumberAssignment

    Read more here: https://learn.microsoft.com/en-us/powershell/module/teams/get-csphonenumberassignment?view=teams-ps

    If you need more details please specify, I haven't got a tenant with voice atm, but have some experience with Poweshell.

    Hi @Theo Gordon ,

    Are you referring to phone number assigned in Teams?

    As far as I know, it's not feasible to retrieve the data from a "deleted" user. If it's a recently deleted user(within 30 days), you can try restoring the user's account and then connect to Teams powershell, run the command below to get its phone number: 

    Get-CsOnlineUser <UserIdentity> | ft LineURI

    But if the user has already been deleted permanently, I am afraid it cannot be retrieved any more.
