I guess there's a couple of possibilities there. It's hard for me to know exactly what the problem was given we don't have your dad here to tell us exactly what his problem was, but here goes.
Firstly, you should be able to specify in Facetime settings, in the Settings app of your iPHone, what details people can Facetime you on. If you have selected your phone number, then people can Facetime you from any device (Mac or iOS) using your phone number. It's probably a good idea to add at least one email address as well though. It's probably a good idea to have these details the same on all your Facetime enabled devices. Secondly, Facetime only seems to work for contacts in your Contacts (previously Address Book). So your dad would need your iPhone number in his Mac Contacts. So subject to those above two points, your dad should be able to Facetime you from his Mac using whatever details you have specified in your Facetime settings, including your iPHone number. I struggle to keep up with which numbers and emails my girlfriend has enabled for Facetime so I tend to just try each one after the other whenever I want to Facetime her from my Mac, and eventually I get through. Recently I've had best success with using her iPHone number though, so this is definitely possible. Her iPad4 is authorised to use her iPhone number for Facetime, so she usually answers my Facetime calls on her iPad.
