How to fix caller ID not showing on Panasonic Telephone?
- N
  Nathaniel BarkerAug 23, 2025
  If caller information is not displayed on your Panasonic Telephone, make sure that you subscribe to a Caller ID service. Also, if your unit is connected to any additional telephone equipment, remove it and plug the unit directly into the wall jack. If you use a DSL/ADSL service, consider connecting a DSL/ADSL filter between the base unit and the telephone line jack. Other telephone equipment may be interfering with this unit. Disconnect the other equipment and try again.

Why is my Panasonic Telephone not recording new messages?

  Rodney EvansAug 29, 2025
  If your Panasonic Telephone is not recording new messages, ensure that the answering system is turned on. If the message memory is full, erase unwanted messages. Check if the recording time is set to 'Greeting Only' and change the setting if needed. If you subscribe to a voice mail service, messages are recorded by your service provider/telephone company, not your telephone. Change the unit’s number of rings setting or contact your service provider/telephone company.

Why can't I hear a dial tone on my Panasonic Telephone?
- J
  Jill SteeleAug 26, 2025
  If you cannot hear a dial tone on your Panasonic Telephone, ensure that you are using the supplied telephone line cord, as your old cord may have a different wiring configuration. Check that the base unit’s AC adaptor or telephone line cord is connected properly. To further diagnose the issue, disconnect the base unit from the telephone line and connect the line to a known working telephone. If the working telephone operates properly, the unit may need repair. If the working telephone does not operate properly, contact your service provider/telephone company.
