When i answer my phone at times, it goes through multiple applications while i am talking on the phone, so i hear constant buzzing.Took it into ATT and they arranged for a new phone, but i still have the same problem. I also cannot figure out how to let the phone ring longer before voicemail picks up.

The power unit that you are using is bad. It is letting an AC signal go into the machine.

if it sounds fine in the head phones and not though the speakers - unit has a faulty pa stage

The buzzing is probably the compressor. You may have a bad air line somewhere. Or, you may have a bad solenoid. These can be check with an ohmmeter.

If you're talking about the answering machine greeting in the base unit, detailed instructions are here: http://www.uniden.com/pdf/DECT1580om.pdf

If you're talking about the voicemail system provided by your local telephone company, each will be different, but my ATT UVerse voicemail is controlled at http://www.att.com/uversecentral and then click My Account, My Services, U-verse Voice Home Page. Hopefully ATT doesn't shuffle around the menus by the time you read this. This is correct as of Dec 2010.

you can try a master reset which you can get on att.com/wireless or call att

it might be due to EMI(electromagnetic interference). if other phones or internet lines r nearby, u can hear the buzzing sound.. if EMI is the cause, then its best to keep the phones isolated from the devices causing them. Good luck!!

Well umh, u used out the phone talking hours. Most phones have a talking limit. Go to the att store and tell them what happened. The fuse out of your phone died out.

We had the same problem. Unplugging the unit and restarting it again solved the problem.

ok you need to hit your bubble button and your favs will show up for good. it is the lower right button on your skid.

sounds like the earpiece is not grounded properly need to have a tech look at this
