Ok head over to https://www.justanswer.com/phone-systems/6psar-panasonic-cordless-phones-stopped-working-no-dial-tone.html they will help you. Please mark this as helpful and follow me.

if you have more than one phone, unplug them all from the phone line then check one phone at a time plugging it in check for dial tone. if doesn't get dial tone unplug from phone line then try the next. I had one get zap and it stopped all phones from working. soon as bad one removed the other phones worked

Hi Pam,
Try these..1...remove your telephone line from base unit and fix it into a working land phone and check whether is it having normal dial tone.If it's having engage tone(beep beep...)remove paralleled phones and re connect to cordless base unit.
2.If line is ok (normal dial tone with full volume) & still display indicates line is busy, your main base unit must be having faulty components inside.Commonly these defects happen in thundering or surges through telephone lines.You have to take full set to a repair shop.
Rana.

You could plug your non-cordless phone into suspicious phone jack to see if you have dial tone-if you dont have dial tone, the line maynot be connected and you should open the jack to see if there is more than 1 cable attached. If there is more than 1 cable attached and you dont have dial tone at other end of cable the cable might be cut or shorted somewhere inbetween. You can test continuity by tying 2 wires together and test with a multimeter on resistance to see if it is open circuit or maybe even short circuit. To test for short circuit, untie the cables and you should not get a reading. If you do have dial tone when you plug in non-cordless phone the distance might be to far for receiver to pick it up(ie..greater than 10 metres). I hope this has been helpful.

Try phoneing or e mailing the number or e mail address on the box or manual of the phones where you bought them from or get in touch with the company that made them and ask for either a refund or technical help. If your landline is working the storm has disconnected something with the base of your phones

Try punching in the number to call first THEN hit talk.. It should dial and call at that point..

Just like when making a call from your cell phn - dial the # first..

good luck ;o)

It is a static buildup in the box. You will have to keep unpluging router for and cable for 10 seconds and reconnect each time.

Please disconnect your cordless phones from telephone jacks throughout the home. The "line in use" is say that you have a short on the line, or a phone off the hook. So disconnect lines, then replug 1 corded phone in to check for dial tone. If working, continue to plug in 1 phone at a time(rechecking working one each time) to find the equipment that is causing you heartache.

check dialing mode matches what exchange is set to DTMF suspect phone is set to dec = decadic or pulse

The problem was the main phone line not the phone itself
