Weak or hard to hear audio
If a caller's voice sounds weak or soft, the signal might be blocked by large
metal objects or walls; you might also be too far from the base, or the
handset's battery may be weak.

Try moving around while you're on a call or moving closer to the base
to see if the sound gets louder.

Make sure the handset's battery is fully charged.

Try adjusting the earpiece volume.
