You may not legally connect any device to an FRS radio which has not been
FCC-certified as part of that radio.  This means that you cannot legally
connect anything to the headset jack other than the headset (or other
device) the manufacturer certified for that particular model of FRS radio.
The FCC has not approved, and is not likely to approve, any phone patch or
interconnection device for FRS radios.  A first-offense violation of this
rule will result in a fine of $10,000.  

GMRS and MURS radios have different rules.  I would look to using them for
this type of interconnection.
