Hi All, I'm looking for an app I can use to make phone calls using my iPad Air WiFi. The User Guide for iOS 8.3 says I can call people in my Contacts, Calendar, Facetime, Messages, Spotlight or Safari. I don't want those restrictions. I want to be able to call anyone in any country who has any type of cell phone, landline, etc. I saw an app called 'RingCredible.' I can use it, but it uses my cell phone number. I don't want that, I'd like to do all my calling with my iPad Air and not need my cell phone or its number for calls. I also saw that the App Store offers plenty of apps for voice calls. There's one catch- I want/need 'bank-level security' for my calls. So, as far as security goes, what's going to be more secure? A cell phone, or an iPad Air WiFi with an 256 bit AES VPN that could be being used at a hotspot? Do you have any advice/recommendations? Thanks. Much Appreciated!
