Can I make phone calls while I record meetings?

No, it's not possible to record meetings and speak on the phone at the same time.

If you receive a call while recording is in progress, the recording will be paused. This is because the microphone can only be used by one function at a time in your phone.

When the call is over, the recording will auto-resume, so you can continue recording the meeting. It is an option that is automatically set under "Settings".
