Hi All,

My pre has started to act up. Every once in a while it mutes the microphone. I have hard reset the device and no luck. I did a test by calling it and it seems like every ten calls or so it does this (no a scientific test by any means). It happens on outgoing calls also but I haven't tested to see how often it happens. You can hear the other side, but nothing is leaving the phone. What I noticed is that it routes the voice to the ear speaker instead. I have tried plugging in a headset to see if it's a problem with the jack but I have kind of ruled that out.

Thanks for any input.
