Hi Guys. I have been making calls using my iMac 5k, using the "call on other devices" feature on the iPhone. Works flawlessly and i love it, except one thing. I have been told the recipient of the call can hear an echo of themselves. I presume this is because the iMac speakers are repeating with a slight delay (understandable). Is there a way to fix this? It does not happen over Facetime. Thanks!
