You are trying to record a meeting while using a Mac, but the microphone keeps connecting to your iPhone? Apart from being annoying, this can result in parts of the meeting not being recorded, and/or echo.
This is due to a new Apple-connectivity feature, but this is a problem which can easily be fixed. All you need to do is disable the Continuity Camera:
On your iPhone, go to Settings > General > AirPlay & Continuity (or AirPlay & Handoff)
Turn off Continuity Camera.
