Cannot switch FaceTime call to iPhone after initiating it on my Mac

I initiated a call on my MacbookPro (running OS X Yosemite), but I cannot transfer it to my iPhone while it's in progress, as advertised on the Continuity feature.

The Apple Support article says:

Transfer the call to your iPhone: Unlock your iPhone, then tap the “Touch to return to call” banner at the top of the screen on your iPhone.

When I unlock my iPhone 6 Plus (running iOS 8.1), however, no banner appears at the top of the screen, and my phone seems to completely ignore the presence of a call.

Since there are no troubleshooting steps listed on the Apple Support guide for this issue, is there any way to troubleshoot this issue or to fix it?

Solution 1:

The continuity is only for cellular calls, which are routed through the iPhone, but doesn’t work with facetime calls.

FaceTime would have to just be configured on both devices and you pick up directly without needing a hand-off from one ringing to cause the other to ring.
