Last year I've had plenty of Facetime calls with my dad (Macbook Pro 2011 to iPhone 4s). The issues started suddenly last year. In October I purchased an iPhone 6. iOS 8.1.2 is installed on both the iPhone 6 and the iphone 4s. I've done a lot of research and tried a lot of things. It's just not possible to use Facetime anymore. Even when I'm using my Macbook Pro it's not working anymore. Here's what always happens: we're both connected to Wifi. The Facetime call goes through, then it says "connecting..." . But nothing happens afterwards. I can use Facetime with a friend of mine who also owns an iPhone 6 without any problems. I can use Skype with my dad without any problems. I don't know anymore what to do about Facetime...I would appreciate any help.
