During a call, other end of the line hears themself
I've setup centrafuse 2.1 with bluesoleil to work with my blackberry pearl. During a call the sound to the speakers sounds good and the mic sounds clear on the other end. But the other person can hear themselves because the mic obviously picks up their voice while they speak and relays it back to them, resulting in an echo. Is there a way to turn off the mic while the other person is speaking? so that I can hear them through the speakers, but they can receive it back in the mic?
