Anyone heard of this with the Beo Com 5, after about 5 minutes on the phone (not in speaker mode) it will mute itself (not completely you can still here a faint sound) until you re-dock it and then it snaps out of it. Happened while I was hold once (after 5 mins) and once when my Wife was on the phone with her mother... (although I've switched off after 5 minutes talking with her mother and theres nothing wrong with me!..er.. yeah) So what do you make of it? Faulty and worth a return? Or just a setting I am missing? Battery is fully charged and have had no problems with battery life on the handset.
