    Phone system is flashing (right back corner) and phone extension is showing Extension In Use. No dial tone, no service. When caller calls in - it reads on their phone that Line is in Use.



    Please provide feedback ASAP.

    I have the same phone, and the same problem. I'm using VOIP and found
    that if I plug the 5840 base directly in to my VOIP unit, the phone works,
    however if it is plugged into any one of my jacks, it displays "Extension in Use" and the line is dead. Other phones work fine on all my jacks...

Phone line doesn't ring


First, lets get rid of the static. Try Feature #86. This will turn off background music. When a music source is not attached you get static.

Enter programming by using Feature XXX66344 password 266344. The display should show "Terminals&Sets" press the top right button with an indicator in the display. The display should show "Show set: ____ enter the extension number that you want to check or program. The display will show ***:name. Press the top right button three times. The display will show Show Line:____ with options to Scan or List. If you select Scan it will show the lines assigned to that phone. If you select List it will start with the first line in your phone system showing one of four states 1- Unassigned, 2- Ring Only, 3- Appear&Ring, 4- Appear only. Change the selection on the line by using the CHNG soft button. This is where line assignments are changed from the four states for each extension.

The only other thing that will keep an extension from ringing is "Do Not Disturb" or DND. Feature 85 and #85 will turn this feature on and Off.

Phone not ringing in normal mode


I believe this is a programming issue.

To change the ringing assignments on extensions enter programming mode by pressing Feature **266344 and password 266344 if it hasn't been changed. You have to do this from an M7310 phone. The top two buttons on each side will move you through programming. The top right button is the SHOW button and the button below it is the NEXT button. The top left button is the HEADER button and the button below it is the BACK button.

Your first category should be TERMINALS & SETS. Press the SHOW button and using the dial pad enter the extension number. The display should show the extension number or name. Press SHOW three times and the display should show LINE ___.
With options to SCAN or LIST. Pressing SCAN will show the lines assigned to the extension. Use the CHNG option to change how the line is on the phone. RING ONLY - UNASSIGNED - APPEAR ONLY - AND APPEAR & RING. Change the lines you want to ring in NORMAL DAY MODE to APPEAR & RING for this extension and press SCAN to move to the next assigned line. Use this same method for any extension you want to change the ringing on.

I am also trying to change the extension names but for some reason when I press program the only thing that shows up is "Program No?" what do i do next?


Start by pressing ** and see what the display shows. If it doesn't show anything but beeps, then you have the wrong phone. Try looking for extension 101 or the first phone in the system.

When you find that phone and press program **1234, you'll go into programming. Dial 004 and press ENTER. If you press ENTER again, you'll be looking at extension 101, or you can dial an extension and be looking at a name. Now you spell out the name on the keypad using the letters and the arrow key if necessary and press ENTER (the center of the Navigator button) to store the name. Notice that the 4th time you press a 3 letter ALPHA key, you will get lower case letters. Punctuation is under the 1, * and # keys and Q appears under the 1 and 7 keys :-)

Next steps you to the next extension and you can just pick up the handset and set it back down to end programming.
