function Set-TeamsCommonAreaPhone {
  <#
  .SYNOPSIS
    Changes settings for a Common Area Phone
  .DESCRIPTION
    Applies settings relevant to a Common Area Phone.
    This includes DisplayName, UsageLocation, License, IP Phone Policy, Calling Policy and Call Park Policy can be applied.
  .PARAMETER UserPrincipalName
    Required. The UPN for the new CommonAreaPhone. Invalid characters are stripped from the provided string
  .PARAMETER DisplayName
    Optional. The Name it will show up as in Teams. Invalid characters are stripped from the provided string
  .PARAMETER UsageLocation
    Required. Two Digit Country Code of the Location of the entity. Should correspond to the Phone Number.
    Before a License can be assigned, the account needs a Usage Location populated.
  .PARAMETER License
    Optional. Specifies the License to be assigned: PhoneSystem or PhoneSystem_VirtualUser
    If not provided, will default to PhoneSystem_VirtualUser
    Unlicensed Objects can exist, but cannot be assigned a phone number
    PhoneSystem is an add-on license and cannot be assigned on its own. it has therefore been deactivated for now.
  .PARAMETER IPPhonePolicy
    Optional. Adds an IP Phone Policy to the User
  .PARAMETER TeamsCallingPolicy
    Optional. Adds a Calling Policy to the User
  .PARAMETER TeamsCallParkPolicy
    Optional. Adds a Call Park Policy to the User
  .PARAMETER PassThru
    Optional. Displays the Object after execution.
  .EXAMPLE
    Set-TeamsCommonAreaPhone -UserPrincipalName MyLobbyPhone@TenantName.onmicrosoft.com -Displayname "Lobby {Phone}"
    Changes the Object MyLobbyPhone@TenantName.onmicrosoft.com. DisplayName will be normalised to "Lobby Phone" and applied.
  .EXAMPLE
    Set-TeamsCommonAreaPhone -UserPrincipalName MyLobbyPhone@TenantName.onmicrosoft.com -UsageLocation US -License CommonAreaPhone
    Changes the Object MyLobbyPhone@TenantName.onmicrosoft.com. Usage Location is set to 'US' and the CommonAreaPhone License is assigned.
  .EXAMPLE
    Set-TeamsCommonAreaPhone -UserPrincipalName MyLobbyPhone@TenantName.onmicrosoft.com -License Office365E3,PhoneSystem
    Changes the Object MyLobbyPhone@TenantName.onmicrosoft.com. Usage Location is required to be set. Assigns the Office 365 E3 License as well as PhoneSystem
  .EXAMPLE
    Set-TeamsCommonAreaPhone -UserPrincipalName "MyLobbyPhone@TenantName.onmicrosoft.com" -IPPhonePolicy "My IPP" -TeamsCallingPolicy "CallP" -TeamsCallParkPolicy "CallPark" -PassThru
    Applies IPPhonePolicy, TeamsCallingPolicy and TeamsCallParkPolicy to the Common Area Phone
    Displays the Common Area Phone Object afterwards
  .INPUTS
    System.String
  .OUTPUTS
    System.Object
  .NOTES
    Execution requires User Admin Role in Azure AD
    This CmdLet deliberately does not apply a Phone Number to the Object. To do so, please run New-TeamsUserVoiceConfig
    or Set-TeamsUserVoiceConfig. For a full Voice Configuration apply a Calling Plan or Online Voice Routing Policy
    a Phone Number and optionally a Tenant Dial Plan.
    This Script only covers relevant elements for Common Area Phones themselves.
  .COMPONENT
    UserManagement
  .FUNCTIONALITY
    Changes a Common Area Phone in AzureAD for use in Teams
