Hi readers, my 1st post so be gentle.. SE k800i, sometimes when I make an outgoing call, the handset will make, & connect the call, but i get no ringing & of course, no speech thru the earpiece or any connected headset, be it wired or bluetooth. (I have proved the fact that the call connects by ringing my landline). The only way to get over this is to re-start the phone. Any1 else had any similar problems?
