Hello & Welcome to Just Answer,
Sorry to hear of any issue you may be having with your phone(s).
May I ask:
1) Do you have a DIFFERENT phone - such as a BASIC CORDED PHONE - that you can connect IN PLACE OF the MAIN BASE UNIT of the Panasonic system? NOTE: This is for TESTING purposes only, and even a borrowed phone will do.
2) Can you CONFIRM that you are going through a "Wireless Home Phone Base" - to get your "landline connection"? If so, have you also reset that wireless base unit (taken power away from the device for a minute or two, then applied power again)?
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved?
I look forward to any further questions or results that you may have.
Thanks, ***** *****--. .-(im)
