How can I change Beti’s phone number?

At the top right, click on the configuration menu (the one with the mesh tool), then go to phones, click on buy Phone, look for your area code, and add the number. After adding the number, in that same page, erase the number your want to remove. And then click on the configuration menu again, then go to departments, edit a department, and then checkmark the new number you just added to attache it to the department, and then click on save.
