Receive and make iPhone call on MacBook or listen on ipad

Apple and its product are well known for eco system built by itself across various electronics sections like watches with iWatch or Apple Watch, smartphones with iPhone, tablets with ipad and laptops with MacBooks. These are devices from different section but give out more comforts and beautiful features when they are connected under same wifi networks and same account, also they are many things that works out well even when you connected to different wifi networks. Also few features with Bluetooth connectivity. We know many beautiful features like photo stream of photos app, notes being in sync across devices connected with same Apple ID and May such like that which helps our lives to live more comfortably. And one more thing is about calls which I noticed recently. That is when you get a call you can attend from MacBook or you can even listen and answer back on ipad, this thing needs one common thing, these devices should be under same wifi network.
