Question about Panasonic KX-TA824PK Phone

1 Answer

Toll restriction override by account code.

I am trying to program my kx-ta824 to be able to override cos3 restrictions by entering an account code after pressing '9' to get a CO-line.
the problem is: after i press '9' and enter the first 3 digits of the account code, i get a busy signal. i tried changing the extension CO-mode to verify-toll, forced, or verify all, in all cases the i get a busy signal after entering the first 3 digits of the account codes entered in program 310. (account codes)
note that all my extension jacks have COS3 for day, lunch and night time. COS3 is restricted from calling 00 (international code) but i want users to be able to access it when an account code is used.
Please help, i went through the progamming manual, operating manual and feature manual and couldn't figure out what i was doing wrong or missing.
i even upgraded the firmare of the machine to version 3.0.2 (up from v1)....nothing changed.

    i am not trying to configure the walking COS, but instead the verify toll feature of the TRS. (1.1.118 Toll Restriction (TRS) Override by Account Code in the feature manual) !

  • fixya825 Feb 17, 2009


    the probem is when i press '9' and grab a CO, i enter one of the codes in 310, but at the third digit i get a busy signal....i am nt able to use the code to make the toll call!!!

    i tried doing the verify all....then when you press 9 you have to follow it by one of the 4 digit codes of 310, i get a busy signal as soon as i enter the 3rd digit...

    i would like to thank you for your help, but at the same time would be gratefull ifyou considered my intellectual level to less than complete stupidity.

    verify toll will change the COS to level 2 which is fine with me.

    i am using SLT not proprietary phones, and have no blinking buttons.

    i have already programmed a similar older pbx by phone programming and everything (TRS override by account code to move from COS 3-5 to COS2) worked perfectly..

  • fixya825 Feb 17, 2009

    humm....i knew it was something simpl...but couldn't find it myself...i guess i was confused by section 1.3.86 which only said by entering the account code before dialing the number...and didn't cross reference section 1.3.2.....

    i thought my description was as clear as possible when i wrote it :)...what i was doing wrond was actually pretty obvious in it now that i am re-reading what i wrote:

    "the problem is: after i press '9' and enter the first 3 digits of the account code"

    Thank you very much for your help!

It's not thatt simple. Look at 1.3.90 in the OM. You need to set a password and an extension COS on a secure set. For example, if you have a spare extension like 114, reclass it to COS 1, give it a password, then you can dial 7*xxxx114# press any line and dial the world.

The SMDR of the Walking COS user will show where it was made from. Needless to say, if the code is compromised, you have no security and no toll restriction, so be prepared to change the extension security code often.

The other variation is that you just change the class of service on those users authorized to make 00 calls so they can do it from their phone and let them use walking COS on a restricted phone.

    Perhaps I wasn't clear. YOU CAN'T OVERRIDE COS WITH COS VERIFY. That's why nothing changed. You have to either change the COS of the extension you're dialing from or use walking COS.

    We set this up in restaurants where you can't call out at all (verify all) without the code. Then we use a set of codes in 310 to let the managers dial out on that phone. You can do the same thing with verify toll, but only those with codes can call ANY toll calls.

    Is that clear?

    Look at your buttons. One of them will flash. Press it and enter your 4-digit code.

    Oh, and when you get to the part that Verify Toll doesn't change the restrictions to COS 1, look into Walking COS.

    The blinking button is FWD/DND

    And I would be grateful if you had told the COMPLETE story at the beginning. The fact that you had COS 2 defined as ability to dial 00, that you were using single line sets, that you actually understood the manuals...oops guess not. Go to section 1.3.2 of the OM. Under Account code entry, you dial 9 either ** or 49 and the account code, then dial your number.

    After that the rest is easy.

I have the Panasonic KX-T7633 and when I dial a certain number is rings engaged and comes up with ACCNT - please how do I unblock this?

You don't. It's looking for an ACCOUNT number, which are assigned by the system manager. The number you have dialed is restricted by class of service. If you have a class override code, you can use that, or go to a different phone.

My phone will NOT let me call out when i dial a number it says its restricted. how do i fix this problem???

Here's a phone system lesson. Panasonic discontinued your TD phone system about 8 years ago, so you either got a super deal or the system has been installed that long ago. Restrictions are programmed into the system by an installer and manager. There's a Class of Service override access by dialing 47 on the intercom and a code. Since the 7436 is a special phone, it's probably the one attached to extension 101. If that phone is restricted, clearly whoever owns the system doesn't want whatever you're dialing to be dialed.

Now you wouldn't be asking "someone on the internet" for instructions on how to beat the restrictions would you?

I didn't think so. Check with the system owner or installer.

Hi, Can you help me my problem. I Need programming manual for KX-ta308. Specially for the restriction of outgoing calls on local extensions. Already downloaded a manual but cannot find outgoing...

Under alphabetic FEATURES, look at TRS (Toll Restriction) and COS (Class Of Service). It explains the concept of call restriction and how to program it.

We have a different 308 in the US, one that was built on a 624 platform, so a 624 features set will work, it just has a smaller number of lines :-)

Dear Sir, I am using KX-TEM824 PABX system and KX-T7730 master phone.I have installed and configured all extension no by installing CD.But i want to block my staff to call in mobile number for eg. number...

That doesn't explain so well in a free forum. Try the features manual under TRS (toll restriction). COS (Class of Service) and Verified Toll calling. With restrictions, you set up a numbering plan that will bar mobile calls, then either verify and override, or alow only certain phones the ability to dial outside calls to those numbers. If you absolutely have to allow access to certain mobiles, you can add them to the Speed Dial tables where the call can be allowed by the fact it's in a speed call table.

It will take you 30-60 minutes to read and set up the programming.

How to block "0" for international calling and mobile calling in our office phone panasonic model no kx-t7730x

As was pointed out to me, you could take a screwdriver and pry the 0 key off the tone pads :-)

Panasonic systems restrict calls by tables called Toll Restriction (TRS). It's a complete section in the installation and programming manual. It involves setting tables, usually in the 302-306 area, then picking a class of service for the phone that acts on the numbers dialed.

In the simplest systems, the TA series, you have 20 restrictions per class 2-5 and one 80 entry exception table. It's a little tricky to set up in that a COS-2 extension has all the restrictions in COS-2 tables, but a COS-5 extension has all the restrictions in COS-2,3,4, and 5 :-)

Your Pana installer can do this fairly quickly, but if you plan on doing it yourself, please read the TRS examples carefully.

Use only for intercom that is why we need to block the out going

There are a couple of things that make this a difficult answer. First of all, Panasonic made 2 different TA-308's, one for the U.S. market and one for the rest of the world. The U.S. 308 is non-expandable.

Pretty much, the TA-s have a similar program, so this specifically applies to the U.S. version, but it should also work for the other. This also assumes that you know how to get into system programming and are familiar with the 3 digit programming of a Panasonic system.

Do you need to allow for emergency dialing? In some areas, you cannot block it. If you don't have to worry about 911, then you can restrict access to outside lines by programming 405-407 for no line access. If you have to allow for 911 or other emergency numbers, then you have to use Toll Restriction and Class of Service.
Programs 601-603 set the COS and the manual has TRS examples, but it basically means you set the COS to something other than 1, like 5, then go into 305 and put all digits into the denied digits (using PAUSE as the wildcard). 911 will override by 309's emergency dial number set.
In passing, program 306 lets you store 80 exception codes to COS restrictions.

Switchboard KX-T7730

The electronic station lock requires a couple of things, first it's dependent on the system, second, it requires some toll restriction programming, and then you can put in a lock code. At a minimum, in a TA-824 series, dial 77 xxxx xxxx #, where xxxx is a 4 digit number repeated twice. That locks the set, but it might not do anything different. It's released by 77 xxxx #. If you need help, consult your programming and features manual, or post back with the model of your phone system. Carl

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.
