the world's best source of information on Panasonic voice processing systems

  • This page will help you get your Panasonic KX-TVA voice processor working in a typical business or home environment, providing both automated attendant and voicemail service, with a Panasonic KX-TD, KX-TA, KX-TAW or KX-TDA series phone system.
  • You can modify the suggested settings to provide the best operation for your particular needs.
  • The work on this page is done AFTER you have made programming changes in your phone system, to prepare it for use with your voice processor.
  • Some of your work will be done from a PC, and some will be done from a phone.
  • "Maintenance Console" is just a fancy stupid name for the software used to program you voice processor. It is provided free, on the CD-ROM packaged with your voice processor.
  • While programming your voice processor, the software will often refer to your "PBX." In this case, PBX means the control unit ("KSU") of your phone system.


  1. This is a new page dealing with new products. Some information may be INACCURATE or INCOMPLETE or in the WRONG order. It will get better. We promise.
  2. Panasonic has published some INCORRECT information. If you RTFM, you may get in TROUBLE.
  3. We revise this page as we learn more. We're all VIRGINS again.
  4. The instructions say that the default password is 1234. That's WRONG. Use "INSTALLER," in all upper-case letters.
  5. HOWEVER, the second time you are asked for a password, you DO use 1234.
  6. The screenshots below may be DIFFERENT from what you see on your PC. Some screenshots were cropped or modified to save space.
  7. The instructions say that the USB drivers are on the CD-ROM. They're NOT on the first CD-ROMs to be distributed (June, July 2005). You can download drivers from
  8. The USB driver may interfere with KX-TD or other Panasonic drivers you may have on your PC. Install the appropriate upgrade from the upgrade site or your CD-ROM.
  9. When you install the USB driver, you may get a warning that Bill Gates has not approved the driver. Bill is a very busy guy, and may not get around to it for a while. Ignore the warning and continue.
  10. Unlike earlier Panasonic voice processors, you CAN'T program with a serial cable. You can program by modem, or through your network, or with a USB cable. This page covers USB programming. We'll add network and modem programming later.
  11. Previous Panasonic voice processors had default programming for use with KX-TD or KX-TA824 phone systems. The default settings for the TVA VPSs are for KX-TDA and KX-TAW systems, and you'll use "quick setup" to set your VPS for other systems.
  12. The initialization sequence takes a few minutes, and you may be tempted to quit too soon. You're not FINISHED until you see bursts of five green "run" LED flashes (which indicated BIG TROUBLE on the older VPSs).
  13. You may have to initialize your VPS several times, to clear out bugs. The less JUNK on your PC, the easier it will be to get going.
  14. Don't be DISCOURAGED. Your VPS will work pretty soon. We promise.
  15. You are an "early adopter," part of an elite group of highly intelligent and frugal technophiles who will influence millions of lesser beings. Enjoy your place in history, and focus on the future. Think how GOOD you'll feel when the setup is over and the robot lady starts whispering in your ear.
  16. Yes, we know this is a LONG page. We may split it in half later. Maybe we wont.
  17. Send comments, suggestions and corrections to

Unlike earlier Panasonic VPSs, you can't program a TVA VPS with a serial cable and null modem adapter. You'll probably use a USB cable.

►TIP: Instead of mounting your voice processor next to the phone system control unit ("KSU"), you can mount it near a PC, so it's easy to make programming changes. It won't take up much space, and the wiring from the VPS to the KSU is very simple -- much simpler than extending a USB cable. (Panasonic recommends that the USB cable be less than about 15 feet long, but you can probably get away with 25 feet.) You may be able to use spare wire pairs that are already in the walls. The VPs can be over 300' from the KSU.

You can also connect your VPS to your Local Area Network, and program from any PC on the LAN that has the software loaded. We'll have instructions for that soon.

You can also program remotely with a PC that has a modem, if the VPS has a modem. We'll have instructions for that soon, too.

Data transfer speed is limited by the throughput limitations of the phone system (typically 19.2kbps for KX-TD and KX-TDA and KX-TAW systems; KX-TA systems may hit 33.6).

Before starting to program the VPS, it must be initialized.
NOTE: you may have to initialize several times before your VPS works right. We're not happy about this, either.
Insert the CD-ROM in your CD-ROM drive. When the first screen appears, click on maintenance console.
A new Window should appear with a "setup launcher" icon. Click on it.
The InstallShield Wizard should then appear.
Click NEXT to continue installation.
Read the license agreement and click on YES.
Choose Destination Location (you can click on BROWSE to change the default if you want) and click on NEXT.
You'll see the progress of the installation.
Installation will complete. Click FINISH, then click YES to copy USB driver files.
Click OK to copy drivers
You should soon see this little window. Click OK
OOPS! You may get this good news even if driver files weren't copied. If it comes up very fast, there is a good chance that the drivers were not on your CD-ROM.  You'll know it didn't work in a minute or two, if after you connect the VPS to your PC, and you don't get the little announcement window telling you that new hardware has been found.

You may also see this warning screen:

If this happens, Here's what you gotta do:

  1. Download drivers from
  2. Uninstall the Panasonic software.
  3. Re-initialize the VPS.
  4. Re-install the software from the CD-ROM.
  5. Follow steps 17 through 24 below.
Connect your voice processor to your PC.
Left click on the KX-TVA Maintenance Console icon on your desktop
Select your VPS model.
Enter the Programmer Code. ►WARNING: Your manual may show that the default password is "1234." That's WRONG. The correct password is "INSTALLER" (all upper case letters).
You should then see the Set Default Parameters screen. In the PBX Type drop-down menu, select the model of your phone system. The Integration Mode shown may automatically change to match the capability of your phone system.
STEP 17 (may not be necessary)
Go to the file folder where holding the downloaded driver files, and click on "Extract all files"
STEP 18 (may not be necessary)
You should then see the Folders Extraction Wizard. Click on NEXT.
STEP 19 (may not be necessary)
You will then select a file folder to hold the un-ZIPed files. A directory will probably come up automatically, but you can click on BROWSE to change it. Click NEXT to proceed.
STEP 20 (may not be necessary)
You should then see a window that shows "Extraction Complete." Click on FINISH.
STEP 21 (may not be necessary)
You should then see a window that shows a file folder containing the drivers. Click on the file icon,
STEP 22 (may not be necessary)
You should then see a window that shows file folders for different versions of Windows. Click on the file icon for your version.
STEP 23 (may not be necessary)
You should then see icons or a list of individual files. You don't have to do anything here, but you might feel better if you know that you have the driver files.
STEP 24 (may not be necessary)
One more check: in Device Manager, you should see the Panasonic VPS USB driver. If it's not there, you should be able to locate it and re-install it. We got it right on the 13th attempt. Don't be discouraged. (Your screen probably won't look the same as the screen shot below.)  
Click on Connect to get a drop-down menu, and then select USB.
You should then see a USB Parameters window. Enter password 1234 (unless you've changed it) and click NEXT.
You should then see a window that says "Connected!" Click on FINISH.
Click on the Utility drop-down menu, and then click on Quick Set Up.
Soon you should see the System Security window. Click on NEXT.
Next you should see the PBX Environment window. Double-Cick on the PBX type shown below "value," and you'll get a dropdown menu where you can select your phone system. The screenshot below is for KX-TDA and KX-TAW phone systems (default). Your screen will be different if you select a different type of phone system. Click on NEXT.
You should next see "Start Auto Configuration?" If your VPS is properly connected to your phone system, and the phone system is programmed for use with a VPS, click on OK.
You should next see an animated screen showing the VPS and the phone system exchanging information. When the animation stops and there's a green check mark next to each entry, click on NEXT.

You should next see the Select Extensions screen. The number of extensions should correspond to the number of extensions (also known as stations and phones) your phone system is equipped for. Unless you have a good reason to make changes here, don't make changes here. Just click NEXT. Don't be concerned about missing names. You'll take care of them soon.

You should next see the Mailbox Edit screen. Just click in the columns below First Name and Last Name and type in the names of people who will have mailboxes. You can tab from first name to last name, and to other parts of the screen. You may have to double-click before you can type. After you've entered the names, click on NEXT. Don't mess around with any other settings now. First get your system working, and later you can play around.
You've been working a long time. Go to the john, take a nap, have a snack, call mom, take a walk, play with your dog, do anything at all. Just get away from the darn computer for awhile. It will be here when you get back. You've come a long way, and will be finished soon. You deserve a break. If you're setting up the system for someone else, till him that the union contract guarantees you a break.

You should next see the Port/Trunk service screen, where you can assign specific services (such as menus) based on the line a call comes in on, or the port in the VPS. We recommend that you leave this screen alone for now, and just click NEXT. Later, we'll show you how to make changes. The important thing now is to make the system do basic stuff.
This is an exciting time. Correct the time and date if necessary, click on Finish and then Yes; and if the gods on Mount Fuji are smiling on you, you should have a working voice processor in a few seconds.
You now should get two confirmations. The PC screen should say "Quick Setup Completed" and the flashing green LED on the VPS should go steady. Congratulations! You did it.
Now it's time for a quick thrill.

Call the extension number of your VPS (usually 107 for the KX-TA624 and 824, 295 for the KX-TD308, 165 for the KX-TD816 and 1232, and maybe 165 for KX-TDA and KX-TAW systems).

You should hear "Welcome to the Panasonic voice mail system..."  If you call into your phone system from the outside, you should get answered by the VPS if a human being doesn't grab the call first.

Now we start customizing. The most important task is conceiving, constructing, and recording the various announcements and menus that callers will hear.

You will start forming the actual menus, by associating an action with a caller's key stroke on a touchtone phone. It's a good idea to write out a script before you start programming the buttons.

Any key stroke can send the caller to a person, or to a group of people in a department, or to a mailbox, or to another menu, or to the main menu, or can repeat the current menu, or allow the caller to type in a few letters of a last name to reach someone, or do other things.

Create a “tree” diagram to design a route leading callers to the desired person, department, mailbox, or next menu. This tree should include all available caller options and cannot be deeper than eight layers. You might want to discuss available options with users before programming the system.

The top of the tree (at left below -- our tree fell down) should include what callers will hear after a brief company greeting (in the TVS50, it should be a replacement for the pre-recorded prompt # 819 -- more about it in the big yellow box below). Then create a branch for each option. Fill in each box so you can easily see what action corresponds to each keystroke, and make sure that your spoken message corresponds to the programming.

Remember that it is possible and often necessary to have one custom service lead to another custom service. For example, if someone presses [1] for sales, you might want another menu to say “for cars, press [1]; for trucks, press [2].” This way callers are routed directly to the person best suited to handle them.

The first menu (Custom 1) could be something like:

"If you know the extension number of the person you are calling, you can dial it at any time. For a staff directory, press one. To dial by name, press two. For sales, press three. For customer service, press four. For travel directions, press five. For our fax number, email address and website, press five. To repeat this menu, press six. Thank you."


see pg 113 in programming manual
  • The next screen is where you start to set up the menus that callers will hear.
  • Type 1 and press ENTER.
  • NOTE: You can establish a maximum of 100 Custom Services with the possible depth of 8 layers.
  • Someone will have to record Custom Service Menus so that callers will know which key to press.
Now you'll enter some settings that affect the way your first menu (custom service 1) works.
  • In "Description," enter a name that makes sense for you, such as "day menu."
  • In items 2 through 5, use the suggested settings. You can change them later if you have a good reason or just feel like playing around.
  • In item 6, you tell the voice processor where you want it to send callers who either have rotary-dial phones, or are too bewildered to do anything.
  • After typing in an entry, the cursor will automatically move to the next position.
  • If you press ENTER, the cursor will move to the next position.
  • You can also use the cursor to move left, right, up and down.
  • If you make a mistake, press the backslash button (\) to move back one screen, and then make your correction.
  • Maybe change the "Call Transfer Anytime" setting to "No."
This parameter specifies the destination to which the call will be transferred. The "Extn." setting (enter "E") enables callers to be transferred directly to their intended party by dialing the extension number. The "Mbx" setting (enter "M") enables callers to leave messages in a mailbox by entering the mailbox number. The "No" setting (enter "N") disables extension transfer and mailbox transfer; only 1-digit entries work (following the Custom Service menu).

This parameter should be set to "No" when Subscriber Service is specified as a Custom Service option and it is desired that digits can be entered very quickly to specify a destination. Therefore, in most cases, "No" is the best setting
for this parameter. This is especially true if you do not want to explain "Call Transfer Any Time" in your Custom
Service menu recording ("If you know the extension number for the person you are calling, you can enter it now.")
  • Don't change the "Wait for Second Digit" setting.
This parameter resolves the problem when the first digit of the extension or mailbox number is the same as one of the Custom Service menu choices. The VPS waits the specified period of time for a second digit to be dialed. If the time period expires without a second digit being entered, the system assumes the caller has selected a menu choice. Use this parameter only if "Call Transfer Anytime" is set to "Extn." or "Mbx".
  • "No DTMF Input Operation" determines what happens when a caller doesn't press any touch-tone button. By default, the call will go to the Operator, usually the person at phone #101. You can change the destination by typing in a letter representing one of the selections near the bottom of the screen, and then type in additional information as needed, such as an extension number.




Fill in the Keypad Assignments, by typing in appropriate letters and numbers.
  • You will now work your way through all the buttons on a touchtone pad, starting with zero.
  • We're showing just one here, but they all look the same.
  • Try to structure your menu with relatively few choices at each level (probably no more than 5). People often try to remember each choice while waiting to see if a better choice is offered, and it's hard to remember more than three.
  • If you offer lots of choices, make one choice to repeat the menu,
  •  such as "R" (7 on key pad) or "star."
  • Make sure you program some function for every possible keystroke on a touchtone pad. If you are only offering a few choices in a particular menu, program the other buttons to send the caller to a receptionist or someone else who can help, or make the extra buttons repeat the menu (type in the letter "l") or go back to the main menu (type "m").
  • Press the backslash key ("\") several times to reach "Program - Service Setting" menu, and repeat steps 27 through 30 as needed, to create additional Custom Service menus.
  • When you are through entering menus, backslash out to the main page and then exit the program, and move down to step 35.
  • NOTE: Callers cannot jump between Custom Service menus more than 8 times.


STEP 32 - OPTIONAL! for Caller ID Routing only
  • Type 1 for "Enter,"
    and press ENTER.
STEP 33 - OPTIONAL! for Caller ID Routing only
Enter a number for the first Caller ID entry, and press ENTER. This is NOT the phone number, just an identifying number for a position on the list. Start with "1."
STEP 34 - OPTIONAL! for Caller ID Routing only
  • Type in a phone number without spaces or punctuation.
  • Press ENTER. The system will then put hyphens into the digit  string.
  • Type in a description.
  • Press ENTER.
  • Indicate destinations for each day part by typing in letters from the bottom of the screen, and then specific destinations. Press ENTER after each entry.
  • "*" (star) substitutes any number (star = wild card). For example, to route all calls from Area Code 201, enter "201 * (star)".
  • To have a "Private" call (no CID provided) automatically forwarded to a desired destination, enter "P".
  • For an "Out of Area" call, enter "O".
  • When you are through with this page, press backslash ("\") to return to the menu shown in in STEP 35, so you can enter another phone number if you like.
  • When you are through entering phone numbers, backslash out to the main page and then exit the program.



Once you have finished entering the settings for each digit in each menu, the menu "messages" or "prompts" should be recorded. Menu messages tell the caller what options are available and what keys correspond to those options, so the messages must match the programming.

IMPORTANT: Unless you make changes, the first thing that callers will hear will be "good morning" or "good afternoon" or "good evening" and "welcome to the voice processing system." These prerecorded phrases are called System Prompts.
You can eliminate or modify these prompts if you want to, so callers will hear your own message as soon as the system answers. (For the KX-TVS50, see section D6 in the appendix of the PDF manual, or section 6.1.4 in the HTML manual.)

IMPORTANT: Make sure you have selected "User 1" not "system" prompt in the custom service setting menus, and the port service or trunk service menus, or your changes will not take effect.
  1. Access the "Message Manager's Main Command Menu": dial the intercom number for the voice processor (usually 165 in KX-TD816, KX-TD1232, KX-TA1232, KX-TAW848; 295 in KX-TD308, 107 in KX-TA624 -- unless you used a different number), then press  #, 6, *, 998 (or 98 for the KX-TD308).
    IMPORTANT: This will not work if a PC is still connected and in the programming mode.
  2. Press [5] to modify messages.
  3. Press [6] to modify the user prompts,
  4. Press [1] to change user prompt 1.
  5. Press [1] to change a specific prompt.
    OR ON NEWER SYSTEMS, press [1] if you want to re-record a prompt with your own voice,
    or press [2] if you want to turn off a prompt.
  6. Enter the prompt number you want to change.
    • Prompt 819 is "welcome to the voice processing system."
    • Prompt 248 is "good afternoon."
    • Prompt 249 is "good evening."
    • Prompt 250 is "good morning."
  7. Continue following instructions. You can press 3 to turn off a prompt.
  8. ►NOTE: by eliminating the pre-recorded prompts, you will cause a delay between the end of ringing and the first sound that callers will hear. To minimize the delay, we recommend that you replace prompt 819 with your own brief message ("Thank you for calling Acme International") which will be be played immediately before your main menu (usually "custom 1").

The next sequence shows you how to record the custom service menus.

  1. Access the "Message Manager's Main Command Menu": dial the intercom number for the voice processor (usually 165, 295 or 107), then press  #, 6, *, 998 (or 98 for the KX-TD308).
    IMPORTANT: This will not work if a PC is still connected and in the programming mode.
  2. Press [5] to modify messages.
  3. Press [4] to change the custom service menu.
  4. You will hear: "Enter the Custom Service number [1] through [100]. To record the Custom Service Exit prompt, press [0]."
  5. Press the button on your touchtone pad corresponding to the custom service menu you want to record or change.
  6. Follow the instructions until all Custom Service prompts have been recorded, using the tree that you created as a guide.
  7. IMPORTANT: After you have entered and recorded all menus, it is important to try the program yourself to see that all functions perform properly. Dial into the system and try all the choices to see if you are routed correctly. Verify that each menu choice works as it should.
