You probably just need to Pair the handset with the base again.
So, you have to set the phone in the main base, not just a charging base.
Some of the AT&T phones need you to disconnect the battery for about a minute to reset (this will not lose you stored numbers). Then pair the phone and base again.
Some models have a PAIR button on the bottom of the base.
Press and hold the PAIR button until the MUTE light on the headset base turns on (about four seconds) and release the button.
Return the headset to the headset base for registration.
Registration may take about 30 seconds to complete. The MUTE light on the headset base turns off. The headset ON/OFF light turns blue
on the first headset registered. The headset ON/OFF light turns orange on the second headset registered.
You should be good to go!
All the best to you,
