Using 6150 as a room bug

[mem]

Hi.
I read somewhere that by temporary connecting a short
on some pins on the 6150 the phone thinks that it connected
to a car handsfree so by seting it to answer a call after 1 ring
you can use it as a room bug (listen in).
BUT I dont remeber how to do it, can someone help ?

The James Bond Trick
If you short-circuit theleft middle and right pins on the bottom of the phone with all connections touching each other, the Nokia software hangs! The profile "Headset" will be activated. Before you do this just activate the "Automatic Answer" in the headset profile and set the ringing volume to "Mute". Now you can use your phone for checking out what people are talking about in a room. Just place it under a table in a room and call it. The phone receives the call without ringing and you can listen to what people are saying.
