Panasonic KX-T7420. There are several of these phones in our office, I would like to know how to reset all extension numbers at each phone and create new ones.

    Ah, yes, thank you. I understand. I also have a question about voice mail...and since I'm here, I hope it's okay to ask....our office actually has both T7420's and T7433's, and now I'm trying to work on changing the initial voicemail message, as well as having each individual extension receive their own voice mail, password to access it, etc. It has been set up before, but I am new to the company and I have no record of anyone's old vm passwords or any other similar information. I've tried looking through both T7433's, did PROGRAM **1234 and it says USR PGM NO instead of SYS PGM, like I've seen in the manuals and other threads.. so the [###] are limited and I'm not quite sure what the next steps are. I suppose I might post this up as another question as well, but If you could please help, I would really appreciate it!

Reset? How about you just program new ones over the old? I'm guessing you mean intercom DSS buttons, so you dial PROGRAM 99, press the button and dial 1+ the new extension STORE. Keep doing that to all the buttons you want to program and then pick up the handset and drop it back down again when you're done.

    Let's pretend you have a TVS/TVM voice mail product. It's the one you dial 165 to get. You need the password for mailbox 999. When you dial 165 from anywhere, dial #6*999 and a password. It will let you adminster the mailboxes and one of the options is to reset the password of an individual mailbox. The messages, as in custom service menus, is administered from a terminal and recorded from mailbox 998. (something like option 5 then 4). If you post your model number of the TVS system, I probably have a manual or you can search the internet for a TVS something installation and user guide.

ON PHONE KX-T7420 NEED TO CHANGE HANDSET RINGTONE . WE HAVE FOUR IN ONE OFFICE AND ALL SAQME RINGTONE.

The phone has 8 ring tones. From the idle phone, press PROGRAM and dial 99. Press the intercom or a CO line button TWICE and dial 2-8 on the keypad (1 is already default). When you're satisfied with the tone, press STORE. You have to do this for each line and the intercom you want to change and you need to do this at each phone. Pick up the handset and drop it back down to exit programming.

Need to change the ringtone on Panaswonic KX-T7420. How do I do that?

I'm going to guess here, sort of. In the TDA's, it's PROGRAM press the button twice, and dial a number and store. So, in your TD system it should be PROGRAM 99 press the button twice, and dial a number from 1-8 (1 being the default) and STORE

You have to do this from each line and intercom you want to change.

Panasonic KX-T7420 New arrival in the company.old employee's message is on voice mail, plus I don't have the password. How do I reset?

You log into the system owner's mailbox (999) and follow the prompts to edit the mailboxes. One of them will let you reset the password.

Need to change password on voicemail extension on

If it's a Panasonic brand voice mail, you administer the system from the System Owner's mailbox (999). With that, you can use option 4 or 5 and reset the mailbox password to any and all mailboxes (except 999 :-)

How do i pre-set an area code so i don't have to dial it every time? The office uses the panasonic kx-t7420 phones. Thanks

What phone system are you using? we will need to know the exact PBX or KSU to help. If your phone is a 7420 could be on a number of units, you will also need a 7430, 7453 or other display phone to program. In some cases this may not be an option or could require programming software by your vender to make work.
Reply and we can take this the next step.

PIN Number

O.K. Here's your solution, but it's only available to you until next Monday. Go here http://public.carl.airpost.net/ and get both TDA EXT PIN files. One is the extension users guide and the other is the admin sequence to reset it. Please comment and/or rate this solution so I know you have it and I can take it down earlier.

This is one of the codes that can't be posted in a public forum.
