Telephone field ALWAYS visible

Hi,

We don't need the Telephone field when a user checks out, so I disabled this field and I disabled it from front-end AND back-end view.
On the checkout page all seems well and the Telephone field is not there as expected.

However, when I fill in the name, etc. and click on save, the name, etc. appears AND the Telephone field label appears too.

I cannot see how to make this field go away. Everything for this field has been set to disabled and not showing.

Please help.
Maurice

Hi Nicolas,

It worked great for the checkout page.

Do you also know where and what to edit for the same effect in the backend Customers->Customers page?
When I open the Customer page, in the Addresses pane, I also have the Telephone label.

In the e-mail that is sent to the customer, the telephone label is also still visible.

Thank you,
Maurice
