My preference is not to use FaceTime while on a call but to use my BlueTooth earpiece. If you have an iPhone, a simple couple of steps can move the call to your phone itself.
Start with the Panorama Preferences > Channels set to Dial using FaceTime.
In FaceTime Preferences > Settings, check Call from iPhone.
On the iPhone, under Settings > Phone > Calls on Other Devices, turn it on and set it to allow calls on the desired Mac.
Back in Panorama, run a procedure with
A Notification should appear showing the number and “Click Call to make this call” with options to Call or Cancel. Click Call.
Once the call is initiated, you’ll see a green bar at the top of your iPhone screen. Touch that and it goes to a screen where you can change the audio to the iPhone or a BlueTooth device.
Once you have it set up you’ll find that it’s very quick and easy and you can automatically call anyone in your database via a procedure.
