Query: Disappointing

Thinking the AT&T company name was reliable, and liking the price for a dual handset model, I bought this set. I put one handset in my home office, and the other downstairs in the family recroom. Initially things seemed to work well, although the sound volume was a bit low even at the highest setting. As the months passed, reception got worse, and there were strange beeps in the background at times (almost as though a fax machine was on the line, although there was no fax activity). After about 8 months they started going out intermittently, and the range droppped terribly. I also own a Panasonic cordless phone, which has been in my kitchen for several years, and which has worked flawlessly for all this time. I'm replacing these AT&T phones with another Panasonic.
