When I received calls on my iPhone 6 my iMac (2011) used to ring also. I could answer my phone from my computer if I was in the other room and it was very convenient. After resetting my Apple password I had to re-login to all my iCloud accounts and I got everything to work again. iMessage/SMS works flawlessly on my iMac and iPhone, but when I get calls it only goes to my phone. My phone is on the same WiFi network as my iMac. Do I need to pair them over Bluetooth to get it to work again?
