We have a Panasonic KXT7731 and our line one needs to be assigned can you help me do this

The "CO Not Assigned" error on your Panasonic KX-T7433 handset indicates that the Central Office (CO) line has not been properly assigned to the handset. Since you've mentioned that other handsets in your office can connect to CO-01 without any issues, the problem seems to be specific to certain handsets. Here are a few steps you can take to troubleshoot and potentially resolve this issue:

1. Restart the Handset: Sometimes, a simple restart can resolve temporary glitches. Try unplugging the handset's power cord for a few seconds and then plugging it back in.
2. Check CO Assignment: Double-check the CO assignment settings on the problematic handsets. Make sure that the CO-01 line is correctly assigned to those handsets. Follow these steps:
   • Press the "Program" button on the handset.
   • Dial 1 (CO Line Access).
   • Dial the line number you want to assign (in your case, 01).
   • Press the "Auto Dial/Store" button to save the assignment.
   • Hang up the handset.
3. Reset the Handset: If reassignment doesn't work, you can try resetting the handset to its default settings. Keep in mind that this will erase any customized settings on the handset. To perform a reset:
   • Make sure the handset is not in use.
   • Press and hold the "Program" button while you reconnect the power cord.
   • Keep holding the "Program" button until the handset displays "Initializing..." and then release the button.
   • The handset will restart and return to its default settings. You'll need to reconfigure any personalized settings afterward.
4. Firmware Update: Check if there are any firmware updates available for the Panasonic KX-T7433 system. Outdated firmware can sometimes cause compatibility issues. Refer to the user manual or Panasonic's official website for instructions on updating the firmware.
5. Contact Panasonic Support: If none of the above steps resolve the issue, it might be best to contact Panasonic's customer support. They can provide specific guidance based on your model and system setup.
6. Physical Check: Ensure that the physical connections and cables related to the CO-01 line are secure and functioning properly. A loose connection could lead to communication problems.

Keep in mind that these steps are general suggestions and may need to be adjusted based on the specific model of your phone system and any unique configurations in your office. If you're not comfortable performing these steps yourself, it's recommended to seek assistance from a professional technician or the manufacturer's support team.

The KX-T7731 isn't an answering machine.

If the voicemail is on an answering machine connected to your phone line, consult its manual/

If the voicemail is on the phone company's server, look up the instructions in the phone book, or conrtact the phone company.

make sure that your service provider has installed 3 individual lines into the building
check that the 3 incoming lines are not all together in the plug at the wall
you may need a telephone technician to check it out

There is a bell symbol on the side with three positions.

Did you not assign a speed dial CO buttton to an extension

Lines are assigned in program 400. Normally, they are assigned by default so someone had to work very hard to unnasign them even though you didn't have the hardware.

Keep pressing the * key on an idle phone. It has 3 steps.

I've never heard of the ability to reassign an intercom button as it's a fixed feature, but maybe so. Start by assigning the lower left phone button back to CO1 and let's see what happens. WIthout picking up the handset, press PROG the button and dial 0+01 STORE or ENTER.
Pick up the handset and drop it back in the cradle to exit programming.

Did that work? Making button 1 into CO1 will drop the programming from the intercom button and it should default back to intercom.
