Hi again and thanks for that information.
OK - let me see if I have this correct:
You have the KX-TG9382 system - with 3 cordless handsets AND
It is being used for connection to a single line AND
Line 2 is UNUSED - and not available.
AND line 1 of the phone line is connect to a "computer".
So does that mean that the computer & internet connection is "dial up" service?
Also, do you have for can acquire (borrow, find, purchase) a DIFFERENT phone (basic corded is best) - to connect to the phone line and TEST for a dial tone?
This is a very basic test, that will tell us if this is a "line issue" or a phone issue.
Another way to TEST is to take the main base unit and one handset to a different location with working phone service (friend, neighbor, etc.) and TEST it there - to see if you can get a dial tone.
Can ANY of these tests be done?
