As @DaveL said, the ComPilot and Paradise don’t work the same for phone calls.
When you paired the ComPilot with your phone, it asked you to share your contact list with it. This allowed you to make phone calls from the ComPilot.
The new P90’s don’t have your contact list available to access. As was said, you can use Siri to make the call. As you rightly pointed out, is a much earlier post on Tap Control (yes it doesn’t work on the P90’s), you can short press to answer a call and long press to reject/end call.
