Dial tone on speaker-phone but no dial tone on line 1

If I understand you correctly, when you leave the handset in the cradle and press a line, you can hear the dial tone. But, if you lift the handset and then select a line you don't hear anything through the headset. If this is correct, I suspect the handset is damaged, the cord is damaged, or if you're lucky, the clips may not be plugged all the way in on both sides. If you have another phone that is the same, you can switch handsets to test this theory.

Intercom button/s provide dial tone when they are pressed. They are required to call other phones on your system.
Sounds like your button is stuck or issue with the motherboard.

LOL Guessing you have turned BGM (background music) on. Without picking up the handset, press "1". Voila! No music.

Hello Tedelen,

Be sure to meet all the requirements of the phone to make calls and to be fully operational. These requirements can be found here (Requires Adobe Acrobat Reader).

To make a phone call follow these instructions:

Making calls with the Handset
1. Pick up the handset and the phone automatically selects the priority line. If the priority line is occupied, it selects an open line.
OR
Pick up the handset and press a LINE button to select a line.
2. Wait for a dial tone, then dial a phone number.
3. Hang up the handset when finished.

Making Calls with the Speakerphone
1. Press the SPEAKER button and the phone automatically selects the priority line. If the priority line is occupied, it selects an open line.
OR
Press a LINE button to select a line.
2. Wait for a dial tone then dial a phone number.
3. Press SPEAKER button when finished.

If you are having problems refer to the given link to the User Guide.

The battery in the handset could be bad . First I would test that the base unit is recieving dial tone by pressing speaker button on base unit. If there is dial tone then problem is in handset or in base unit communication to handset. Try resetting power to base unit. Check manual for any re-initialization procedure. If the base unit is not receiving dial tone then I would test that the phone line is delivering dial tone to the base unit by connecting a known good phone to the line cord. If the dial tone is not present , problem could be in line cord from outlet, outlet, building wiring, or service provider.

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.

You have the headset feature active on your phone. You more than likely dialed the headset code inadvertently, there are two ways to turn this feature off. 1) If you have a headset key programed on a key on your phone turn it off. 2) Dial the headset off code, you can obtain this from your local admin.
Sorry I didn't have quick fix for you.

I would double check your phone cord. There is usually 2 jacks in the back of the fax machine. 1 is for Line, and 1 is for phone.
Your phone cord should be hooked up in the LINE jack that goes to the wall.
I would also double check your phone cord on another phone to make sure the cord is good.
If you look at the clear connector that you plug into your wall and fax machine, does it have 4 copper/gold color wires contacts imbedded in the clear plastic connector?

Another thing to try, if you fax machine has a Line and a Phone connector, try plugging in a phone in the PHONE connector. Then hook up another phone cord going from the LINE to the WALL jack.
If you get a dial tone on your Phone, then you know you have it connected correctly. If no dial tone, then I would go back to the phone cord.
check those things and get back to me and I will see if I can help you with more suggestions.
Good luck.

If you are sure that both cords are good (use another phone to test), make sure the Speaker button light is off. If both lines stay lit up when the phone is on the hook, your phones has problems. Can't help you there.

Hope this helps, and please rate my advice.

You’ll need either a 6-button or a 24-button set SPIRIT CS administration.

First the control unit ADMIN switch must be ON, the administration overlay must be in place on station 10, and the set must be plugged into control unit jack 10 (call processing is interrupted only at station 10).

After moving the admin switch, and before dialing Ftr 7 -
From station 10 press intercom,
Press speaker,
Dial *0,
Dial 1,
Then Press Ftr 7.

Each line indicator light will show the current dialing type for that line. If the light is OFF, that line is set for touch tone dialing. If the light is ON, the line is set for dial pulse
dialing.

To change the dialing type for a line or lines, press the line button(s) and dial the
appropriate digit from the table below. You may press more than one line button to make the change on more than one line. If you enter a digit without first pressing a line button you will hear the error tone.

Be sure to turn the admin switch back off when you’re finished.
