Does the headset automatically activate the cell phone interface if a call

The cell phone interface is active immediately upon plugging the
interface cable into both the phone and the headset battery pack. In
other words, you are able to hear the phone number tones when you are
dialing, as well as when the cell phone is sending or receiving a call.

If so, does it automatically mute the cell phone audio
if the aircraft audio is active?

No, the cell phone audio is always active, regardless of reception or
transmission over the com radios. Only the music audio has the mute
feature, but this can be disabled by pressing and holding one of the
buttons on the battery pack (I forgot which as I do not use the music
input feature of the headsets).
