Why can't I rec or make calls?

What is happening when a call comes in are they getting a busy signal? If so your line is shorted out.. unplug all phones and see if caller hears a ring.. Then 1 at a time plug phones in. Check for a dial tone and press a digit, hang up and check and see if dial tone returns, repeat this on all phones, until you get to the phone that does not give you dial tone back after dialing a digit. That will be your bad phone... If the line was ring busy after all phones unplugged, call repair service..

Call forward will not turn off, have tried *74 & *73 , have rebooted and turned off then on, call divert symbol still on and phone calls still diverted.

To set Unconditional Call Forward ON Dial "*72" for a dial tone. Dial the forwarding number followed by "#". Wait for dial tone. LCD will display "Call FWD Activated"
To Cancel Unconditional Call Forward: dial "*73" and get the dial tone, then hang up. LCD will display "Call FWD Activated

but, since you have tried those two, it could be that there might still be a different type of call forward option that is still ON, on your phone like Busy Call Forward and Delayed Call Forward 1. To Cancel Busy Call Forward: dial "*91". Wait for dial tone. Hang up.
2.To Cancel Delayed Call Forward: Dial "*93" for a dial tone, then hang up.

Let me provide you a link to the website which I used as a reference for your future reference.

I cannot send fax

Hi there!

For you to send a fax with the Brother Fax you can try these steps:

1. First make sure that you have a dial tone by lifting the handset or just by pressing the hook/speakerphone button. Once you have verified you have a dial tone press the hook button again to return to the main screen or hang up the handset. LCD should display the date & time

If you don't have a dial tone make sure that the telephone line cord is connected on the fax machine's Line jack. If you don't have a dial tone still, connect it to another working outlet. If you don't have a dial tone still, connect a working telephone on the wall jack to see if you'll get a dial tone. If you get a dial tone on the regular phone then problem is either with the line cord or the fax machine.

2. Once you have the date & time on the LCD screen, Load the document that you want to send on the automatic document feeder which is directly above the LCD screen.

3. The LCD screen should change from the date/time to "Enter Fax No. & Press Start" Once you got this screen dial the fax number and then press Start.

Hope this helps. Rate if it works.

L7780 cannot get dial tone on 2-line outlet. Are there any work arounds to this problem?

There is a problem either with the Line Interface Unit (LIU, also known as the fax/phone line connector) or the fax hardware, because the unit is having problems sending or receiving faxes. The unit may hang on "Initializing." This document explains how to troubleshoot the LIU and fax hardware. SOLUTION: Please perform the following: Front panel hangs on "Initializing"
  1. Pull the power cord connector from the back of the base unit to recover from the error.
  2. Unplug the LIU from the back of the ADF. It is located on the left side (facing it), and is where you plug in the telephone lines.
  3. Plug the power cord back in, power it up, and see if it hangs without the LIU inserted.
  4. If it does not hang without the LIU inserted, power the unit down, plug the LIU back in, and power it back up. If it hangs, the LIU is faulty.
  5. If it does hang without the LIU attached, unplug the ADF from the base and see if it hangs. If it does, the base is faulty.
Testing the LIU The primary test for the LIU is whether or not you get a dial tone. Sometimes, you need to re-seat the phone line several times to get a good connection. If after trying the things below, there is still no dial tone, or initialization hangs, the LIU may need to be replaced.
  1. Verify that the phone line is connected directly from the wall jack to the plug in the LIU that says "To Wall Jack."
  2. Verify that the LIU is plugged securely into the product. If it is not, there will be a message at power-up saying the LIU is not connected. If it is, the date and time will display.
  3. If the LIU was re-seated, cycle the power on the unit. The unit should display the date and time.
  4. Unplug all other accessories, like a telephone answering machine or modem. If the LIU appears to work fine after unplugging them, these accessories may be interfering.
  5. Place a document in the Automatic Document Feeder (ADF). The display will flash "Document Loaded."
  6. Press Start Fax to verify there is a dial tone. If so, try sending a fax.
  7. If there is not a dial tone, unplug the product from the wall jack, and plug in a regular telephone to verify there is a dial tone at the wall jack.
  8. If there is no dial tone on the telephone, the wall jack or phone line may be faulty

Don't confuse the two. In most systems, the RECALL button gives you new dial tone on the line you're currently on, and the REDIAL function will dial the last number dialed or a saved number.

Since you're asking about a phone and did not list the SYSTEM, if you set has Last Number (LNR) or just redial, when you press the button, it will either try to use the last line dialed, or you may have to select an outside line and get a dial tone, then press the LNR button. It will dial out. If you press the RECALL button, it will drop your present call and give you new dial tone without having to hang up, pick up the handset, and select a line. You may actually have to press both buttons to effect a LNR sequence.

Phone won't transfer to next free line when a second call comes

If you are not getting a dial tone then something is holding the line off hook. Disconnect any other device you have on your lines and check to see if you get your dial tone back. If you still have no dial tone unplug each phone and check again. You may have to disconnect everything for a minute or two so the phone company will reset its equipment. Plug in your phones one at a time and check your dial tone every time you add something new.

If you add something and you loose your dial tone immediately you may have a crossed connection in the wall socket, any splitters or in the phone plug. Check to make sure all of the wires in those sockets are straight before you plug in your phone wire.

If you add your CC machine and everything is good but it fails after you run a transaction you will have to contact the supplier of your CC machine. It is not hanging up the line.

There was a power surge, and now my phone is stuck on pulse dialing, how do I get it back to tone? I can use the star key to bypass the pulse and put the phone on tone, but it only works one call at a...

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

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.
