With Mac's OS X Yosemite, you can now answer a call from an iPhone on a Mac device, using the Continuity feature. To do this, you will need to be signed into the same iCloud service, and FaceTime, across both devices. Your iPhone has to have iOS 8 installed, while the Mac has to have OS X Yosemite. Both devices also needs to be on the same wifi network. Wifi calling from your iPhone has to be turned off. When you get an incoming call, a notification will pop up at the top corner of the Mac devices' display. You can answer, send the caller a message, or send it to voicemail.
