    I bought this phone set after deciding that I wanted a less cheap phone ... with answering machine included ... it was, I thought, a good investment ... now, I'm supposed to pay extra for "Premium Assistance Plan?  I don't think so!  Doesn't anyone have any answers for me???

Make sure the battery is charged. If the battery is low either because it is old and doesn't hold a charge or needs to be charged, the audio will sound like your talking from the bottom of a swimming pool.

Our line one cuts out even when we're talking on it & we can just barely hear the person on the line but they can hear us clearly. We have unplugged the phone's power cord & plugged it back in...

I have the same sort of My Vtech sorta 'cuts out' when there is noise at my hosue. The person I'm talking to can still hear me but I can't hear them. If my son starts crying or there's any other loudish type noises on my end, it's like the phone is trying to cutout my background noise, but all it's cutting out is the person talking to me. It's not that the noises in my house are loud and I jsut can't hear the person I"m talking to, b/c if i cover the mouth peice then no matter how loud the sound in my house is i can still hear the person i'm talking to but I HAVE to keep the mouth peice covered. It's really annoying!

K800i no call volume

A problem with the internal microphone, or the contact between it and the circuit board, more often on the later, cause a condenser microphone is quite rugged. Anyway, it really needs professional attention, but if you're adventurous enough all you need is a T5 or T6 screw driver to open. Clean it, but don't use any liquid.
Again, it's a delicate job, better handled by professional on that field. You might end up losing your phone altogether.

Hand set goes dead

Next time it goes dead, try wiggling the cord where it plugs in the handset and where it plugs into the phone. If the problem goes away, you will need a new cord.

Hope this helps, and if so, please rate my advice.
