Hi there and welcome
Can you please remove the power to the base unit and the batteries from the handset
Then wait 10 minutes, connect the power to the base unit, put the batteries in the handset and tell me if you can now get a dialtone please.
thanks, ***** ***** possible your provide is having an outage at the moment.
How long have you had this issue for?
ok, it is very likely an issue with your provider, who is your phone provider?
how often has this been occurring in the last month and do you have another phone there for a test?
how do you mean your landline also?
The Panasonic is your landline correct? Or you Do have a different phone there as well?
