Nokia headset hands-free have a button to call up the voice tag facility. Is it possible to redirect this to dial a fixed speed dial stored number?
I'm happy to pay real money to anyone who can provide a flash image for this or tell me exactly how to do this!

Also, anyone know how an in car hands-free unit operates the radio mute facility?, is there some output from the phone to indicate it is in a call?

I want to make alarm units which will dial out on alarm (eg, a PIR) and enable an external amplifier while a call (incoming or outgoing) is in progress.

TIA, Pete.
