Is this a company phone? If so, CO stands for Call Out. This error occurs when your main phone system has lost it's programming and there is no outside line identified. You'll need whomever works on your phone system to program it for you.

How to get incoming calls to two handsets

The system should be configured so that the desired lines, whether CO or extensions, are set to "Appear and Ring" on each set.
Config... Terminals&sets... Show Set... (enter #)... Find...Line Access... Line Assignments... Show Line (enter #)... set to "Appear and Ring" on each set that needs to ring.

You can also have a line "Ring Only" without an appearance (dedicated button), in which case it will show as an intercom call.

A180 just showing base and no response

Is the ringer turned off? Or is the volume on the ring tone set too low? Another possibility is that the phone isn't set to receive incoming calls - the Siemens phones I've owned allowed one to specify which handsets could handle incoming calls and outgoing calls on each line.

KX-T7431 try to dial out and dispaly says CO Not assigned, I cannot answer calls either!!!! Hellllppppp

What has happened is that the CO1 CO2 etc buttons have not been programmed to dial the access code for an outside line. You can do this manually by dialling 9 then the number you wish to call. You need to enter the programing mode from the default extension usually EXTN 20 or 21. You need to go into the options and assign the digit 9 and a pause (P). The system will allow you to set different options such as if someone is on CO1 and another user dials 9 from another extension, the system will then assign the next free exchange line, again this must be programmed via the default extension. Let me know if you need further help.

Determining which CO you get when pressing 9

Set outgoing line preference.
Or simply swap the CO1 and CO2 line plugs.
The plug from your service provider that enters in CO1 put it in CO2 port and vice versa.You may need alittle config as well.

Panasonic KX-T7730, we have a 824 phone system and cordless handsets (kx-tg1711) we cannot make outgoing calls on these handests but can take incoming calls and can transfer calls. how do we programme

  • Locate the program and auto-store button on your telephone. You will be using these to customize many of the features on your KX-T7730. The program button is used to enter or exit programming.

  • 2

    Program your outgoing line preference, i.e., the line you prefer to seize when you go off hook. Press "Program" "1" "1" "store" for no line. Press "Program" "1" "2" "Store" for an idle outside line. Press "Program" "1" "3" "Outside Line Number" "Store" for an assigned outside line. The outside line number will be a single or double-digit number that is set through your phone system.

  • 3

    Program your incoming line preference, i.e., the line you prefer to answer when you go off hook. Press "Program" "2" "1 "Store" for no line. Press "Program "2" "2" "Store" for ringing line. Press "Program" "3" "Outside Line Number" "Store" for an assigned outside line.

  • 4

    Program your flexible CO buttons. These are the inner row of 12 lighted buttons. Your outside lines need to be programmed to these--you can choose any of these 12 buttons in any order. Press "Program" "CO Button" "0" "Outside Line Number" "Store." The outside line number will be a single or double-digit number that is set through your phone system.

  • 5

    Program any other unused flexible CO buttons for an extension number or any frequently dialed phone number. Press "Program" "CO button" "1" "Extension Number" "Store" or "Program" "CO Button" "2" "9 + Phone Number" "Store". A "9" must be entered at the beginning of a phone number to tell your phone system to seize an outside line before dialing, e.g., "9-1-212-555-1234."

  • 6

    Locate the programmable feature buttons (the row of 12 solid buttons on the right). These buttons are basically one-touch buttons that can be set for extension numbers or phone numbers. Press "Program" "(PF) Button" "Extension Number" "Store" or "Program" "(PF) Button" "9 + Phone Number" "Store." Remember to press "Program" again to exit programming.

  • 7

    Locate your "FWD/DND" button. This button is used for setting "Call Forward" or "Do Not Disturb" on your telephone. To set call forwarding, go "off-hook" either by lifting the receiver or pressing speakerphone. Make sure you go to intercom and not an outside line. To forward all calls, go off-hook, press "FWD/DND" "1" "extension number" (the extension number that you wish to forward all your calls to) "#". After you hear a confirmation tone, place the receiver on-hook. The steps to set call forwarding for busy/no answer are the same as above, except you will press "2" in place of "1". To cancel call forwarding, press "0" in place of "1".

  • 8

    Program "Do Not Disturb," which stops your phone from ringing--any callers will just hear a DND tone. To program, go off-hook, press "Program" "4" "#" on-hook, to set. Press "0" instead of "4" to cancel.

  • 9

    Locate the message button--this works in coordination with your message light at the top right of your telephone. If the light is lit, press "message" to hear a message left to you either by another extension or a voice mail system. The message button can only be programmed as a message or one-touch button. To program as a message, press "Program" "Message" "3" "Store." To program as a one-touch, press "Program" "Message" "1" "Extension Number" or "Program" "Message: "2" "9 + phone number."

  • 10

    Return your KX-T7730 to its default settings by pressing "Program" "#" "*" "Store."

    I need to record an listings of our holiday closings and assign a # in our outgoing message if someone wants to hear the closings.

    You should call a tech out or tech support. You need to program a Virtual extension to make the closing listings in and assign the 1 key options in your main greeting. You need cosession software to connect to the voicemail.

    When we installed our kx ta1232 our children were young so it was programed for them not to be able to make or receive phone calls.Now that they are older we want them to be able to make and receive phone...

    I think I've stepped into the Twilight Zone. Asked and answered a few days ago, but here's the long answer.

    If you don't have a complete set of manuals, go here

    At the very least, you need the FEATURES manual and the PROGRAMMING manual. Since you're the only one with programming access to the 1232, you'll have to find out HOW the system was programmed. There are several ways to restrict extensions. The easiest is COS. The FEATURES manual, page 194 describes setting up Toll Restriction. The companion to that is 500-514 which describe how the phones will perform when different COS's are assigned. Program option 601 defines a station class. COS 7&8 are the most restrictive, meaning you can't dial out, and 1 is the most permissive.

    Besides COS, a phone has to have lines assigned to it in order to make calls. That could be as simple as mapping the CO's to buttons, or as complex as physically assigning the lines in programming. Button programming starts with a display phone on the extension and using PROGRAM 99 and pressing the buttons to see if they are assigned. 0xx STORE saves CO's to buttons. If they are assigned, they may also be restricted. Those are the 605&606 areas I mentioned in the previous post.

    That pretty much covers outgoing calls. Your toll restriction tables reside in 301-305 for restrictions and 306-310 for allow numbers in COS 2-6. Toll tables and ARS plans can take minutes or hours to design, it just depends on the complexity of the situation.

    Incoming calls are probably just the ringing assignments in 603&604. Changing each extension from NoRing to Immediate will solve the incoming ring problem.

    I think the TA-1232 was sold as a non-restricted DIY system :-)
    It's a dumbed-down TD-1232 system. Believe it or not, there's even a DOS based programming tool that you can get. If you get desperate, you might want to contact me at for arrangements. You need a system with a serial port and a DB-25 male to whatever your serial port needs cable to program it.

    Tel KX-T7330

    The system that the 7330 is connected to controls how you program it and how it behaves.

    In the U.S. and for only a short time, the 7330 phones were connected to a TA-624. In fact, those phones were called "Euro Style" so you may be in the U.K.

    I don't recall if they have a PROGRAM switch in the back or a PROGRAM button on the face, but they are programmed with PROGRAM press the button you want to program and read the display.

    In Panasonic, all C.O. lines are assigned with 0 plus the CO number 1-6 in a 624's case and STORE. So you can reprogram the buttons in top to bottom or bottom to top order with 01 STORE 02 STORE etc. In passing, all extensions are programmed with 1 plus the 3 digit extension number as in 1101, 1102,1103 etc.

    If the puttons are physically sticky, you can use alcohol and clean them, or just reassign them.

    I hope this helps :-)

    Group forwarding after a delay

    In memory block 4-1 for the extension's port, The Lkey for the CO line is lit green for immediate ringing, red for delayed ringing, and off for no ringing.

    In memory block 1-1-77 you enter the CO's delayed ringing timer in seconds.

    I wouldn't try and deal with seperating into tenants.

    What I would suggest is in 4-19 restrict outbound trunk access (corresponding Lkey for CO line is lit to restrict)
    For example:
    Stations 1-4 would not be allowed to dial out on CO lines 5-6
    Stations 5-6 would not be allowed to dial out on CO lines 1-4

    This way Company A is not tying up Company B's CO lines for outbound calls and vice-versa.
