How to modify telephoneNumber AD user property ?

Hello,

I am getting the following error once I changed the Telephone number for an AD user.

Type the new TELEPHONE Number:: 3034938004

Are you sure, you want to replace the following Title "303-493-8004" by "3034938004" (Y/N): y
Set-ADUser : A parameter cannot be found that matches parameter name 'telephoneNumber'.
At C:\scripts\AD\test.ps1:136 char:58
+                                 Get-ADUser $AD_User.sAMAccountName  | Set-ADUser -telephoneNumber $Input ...
+                                                                                  ~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Set-ADUser], ParameterBindingException
    + FullyQualifiedErrorId : NamedParameterNotFound,Microsoft.ActiveDirectory.Management.Commands.SetADUser

Thanks for your help,
