20 Most Recent Panasonic KX-T7420 Corded Phone Questions & Answers

Press the PROGRAM button in the row of buttons just above the number pad. If you need a manual, you may download a copy here. You'll probably also want a manual for whatever main unit your phone is connected to, since much of the programming is actually done on that.

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.

There are 2 things that would prevent you from being able to answer a ringing phone by picking up the handset. Your phone has to be ringing, and you need to set preferred line ringing on incoming calls.

The second part is easy. Press PROGRAM 99 and dial 22 STORE on your phone. Now when a call rings on your phone you can pick it up. If you can't, then your phone is not ringing.

Ringing is set in system programming.

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.

Voicemail passwords are in the VM system, not the phone system. You add and delete mailboxes and reset passwords from the VM owner's mailbox (999).

There is an installer's password to your TD phone system, it is controlled from the manager's or attendant's phone. If you don't know it, you can't mess up your system. The installation manula has instructions.

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.

You add a Panasonic brand voice mail system. You can do it yourself, but it's easier to call a dealer. You have to have a specific issue software on your TD phone system and it requires programming, both in the voice mail and the KSU. I charge about $700 for the hardware and programming, your Pana dealer will probably charge about the same.

If you want to gamble, you can probably pick up a used TVS voice mail box for less than $400, but again, there are so many boxes that don't work. As a minimum, a TVA-50 would be best, since it's the current manufacture and it can be upgraded.

Program 99 press the button and dial 8 165 STORE. That assumes that you're using the default VM access code.

Take a look at the manual. One of the bits in programming deals with the status of the FWD/DND button. You can make it light solid for FWD and flash for DND. There are other ways to intercept the calls, but trust me, this is the cleanest. You set 7104 165 # and it will forward always on no answer after x rings. Those rings are set system wide and can be adjusted in programming.

If you sit down wiht the PG manual, pay attentiion to programs 202,203,619 and 990 area 9 bits 3&4. A ring cycle is about 6 seconds and the default intercept is TWELVE rings....you should adjust that to no more that 4.

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.

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 :-)

Actually, you have a Panasonic TD phone system and a 7420 phone, but no matter. The feature you have is probably "idle line preference" or "preferred Line Assignment-Outgoing". In TD systems by default, you select lines from highest to lowest. If you only have 2 lines and PLA is set, you get line 2 then line 1. You can change it to get line 1 first, or chage the trunk access order. The first is something you can do from each phone, the second requires access to system programming. The bad thing about the first solution is if line 1 is busy, you won't get any line. The second will give you the entire trunk group.

Anyway, from each phone without picking up the handset, press PROGRAM 99 and dial 1301 STORE. That will give you line 1 when you pick up the handset. Just so you know or can change it, 11 is none, 12 is idle line, 13xx is specific line and 1+the intercom is intercom. Pick up the handset and drop it back down to exit programming.

As far as the noisy line, it's probably a central office issue. It's hard to test as that line is the outer pair of the jack that plugs into the phone sytsem (RJ-14 pair 2), but you can probably take a regular phone and test it at the demarc point.
