Compliments for their support!
One question: you can edit the contact page by inserting an additional field such as “phone”?

Thanks for your help!

At the moment the fields in the contact form are fixed and cannot be configured. You can provide the text asking your users to provide the phone number in the Message field.

A possible solution would be very good, waiting to change fields
Forms of Contact.

But how can you do? How can you enter text that asks users
to provide the phone number in messages?
Thannks!!

If you add the contact page from the template, there is a text section above the form that you can edit. If you add the contact form with an image from the template there is no text section but you can add one by following the instructions here http://www.ubik.com/tutorial/en/mobilizer/editor_textarea.html
