connection to the empeg is just a 3.5mm mono jack

Looks like this noise cancelling mike array is too good to not use for anything else.
How difficult would it be to share this mike with a hands-free cell phone?

I believe my hands-free phone kit has a signal-out that can be used to silence the radio. Would this be strong enough to also drive a relay that switches the mike from Mark to the cell phone?
