If the handset is not responding normally, you may need to reset your telephone system. Complete the following steps to reset the telephone system:
Step 1: Disconnect the power to the telephone base.

Step 2: Disconnect the handset battery.

Step 3: Wait a few minutes and then reconnect the power to the telephone base.

Step 4: Reconnect the handset battery

Step 5: Wait about one minute for the handset to re-establish a link with the telephone base and then test the phone again.

I disconnected the battery, waited a few seconds, reconnected the battery and set it on the charger. Working great!

Did you recently replace you old phones with these phones? Maybe the old handset of the phones are interfering with them...remove batteries from old handsets, as they may be searching.

hould fix the problem.

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.
