I want to add more than a phone in contact

Hello First, congratulations on the template, I really like it. I have a need that I don't know how to solve. I have two phone numbers and no faxes. I would like to add two phones and keep the headset icon in addition to the option to call directly. If I use one of the telephones as a fax, it won't let me call when I press and the icon it shows is not correct. How can I do this? Thanks a lot.
