How do I fix a home phone that sounds scratchy or robotic to callers?
Answer
Power down the phone if it has a power cord, disconnect the phone line from the handset/base and the modem for two minutes, then reconnect firmly to the modem’s Phone/TEL port. Retest a call; poor seating or a noisy line cord often causes robotic audio.
Before you start: stop right away if…
- Unplug only phone and modem cords as described; do not open sealed modem equipment.
Follow these steps
Power down and disconnect the line
If the phone or base has a power cord, unplug it. Unplug the phone line from both the handset/base and the modem (or wall jack) and leave everything disconnected for about 2 minutes.
You should see: The phone is fully powered down and the line is disconnected at both ends.
Reconnect firmly to the Phone/TEL port
Plug the phone line firmly into the modem’s Phone or TEL port and into the phone base until it clicks. Restore phone power if used. Avoid half-seated connectors.
You should see: Cables feel secure and the phone powers back on with dial tone.
Reseat the modem phone lead once more
Unplug the phone lead from the modem’s TEL/Phone port and plug it back in firmly. Make a test call and ask the other person whether the scratchy or robotic sound is gone.
You should see: Call quality sounds normal to the other party, or you confirm the cord/port still needs replacement.
Swap cord or phone if audio is still bad
Try a different phone cord and a simple corded phone if available. If a corded phone is clear but a cordless set is not, replace or reset the cordless base. If every phone sounds robotic, contact your phone provider and report poor voice quality after reseating.
You should see: You isolate a bad cord/handset or have a clear report for the provider.

Extra tips
What to look for: Callers report scratchy or robotic audio while your dial tone may still work
Before you change anything: Know whether the phone plugs into a modem/gateway Phone or TEL port. Try a second corded phone if you have one. Note whether the problem is on every call or only cordless handsets. Do not share account passwords with unexpected callers.
