Hello & Welcome to Just Answer,
I'm Greg and will do my best to assist you today.
Sorry to hear of any issue you are having with your phones.
To help you with this issue, may I ask:
1) What phone service provider (phone company) you have for this phone line?
2) Can you CONFIRM that the messages are stored in a "Voicemail system" - with your service provider (vs. the built-in "Answering system" of the Panasonic)?
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)
