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) The FULL Model Number of the phone system you are working with? Since this is a cordless system, that model should be printed on a sticker on the bottom or back of the MAIN base and START with KX-TG, but NOT have an "A" in it (that is for the cordless handsets or chargers.
2) What phone service provider (phone company) you have for this phone line?
3) HOW LONG did you have the phone CORD disconnected - before reconnecting it?
4) Do you have ANY other devices (NOT part of the Panasonic system) attached to this same phone line and if so, are they working properly?
Please REPLY using the box below and the SEND button.
I see it has been a few days and I haven't seen a response on this page, so 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)
