title: How to tranfer the call from one bluetooth device to other bluetooth device from iPhone?
body: <p>I have two bluetooth devices (MFi) connected to the iPhone.Both of these devices support HFP. If Call is accepted from one device(does not have hardware like microphone and speaker),after that I would like to route the call to other device(headset).Is there any API to accomplish this from app or any other way to achieve the same. </p>
  
  <p>I found the following relevant link</p>

  <p>Is there any way to simulate the accept button of the headset from the app or transfer the call session from one HFP device to other HFP device ? </p>
