My att cordless phone mics
It's not that the handsets have bad mics, the problem is in the base unit. That's what's sending audio into the phone line, and something has gone wrong there. Try unplugging the power from the base and give it a minute, then reconnect the power. This will allow the computer inside to reset and may straighten out the trouble. If it doesn't, you're probably best off replacing the system.
AT&T doesn't say anything on their site about service, just to call their Customer Support and Service Center at 1-800-222-3111 for more information. If your phone is out of warranty, it's probably easier and maybe less expensive to buy new.
