Question about Panasonic KX-T7453 Corded Phone

No Light to show off hook

I had someone switch desks. I moved their extension number to a different jack. The only thing that doesn't work is when he has his phone off hook, his extension doesn't light up on any other phone to show it is in use. I don't know if it has to do with moving the extension to a different jack in programming or not. Thanks!

Start by going to the phones that need to have the button fixed.
[Program], [9][9], [Button] (you should see an incorrect ext number), [2], [Correct ext number] and [Store]
You may need to repeat this at all phones that need the corrected light.

I have a NEC DTH-8D-1 Corded phone. I moved my desk and plugged the phone in at a different phone line port and the screen now reads "Initialize." What is it asking for? How do I set up my phone at th

Your extension is hardwired to 1 jack, if you plug in somewhere else you'll be lucky if the jack is active with another extension. Someone needs to re-wire your extension in the phone room to your new jack. If it won't activate but says Initialize, then that jack probably has a live fax line or analog extension, but not a digital line that works on your phone.

The only way a password will stay with a phone is if the "Extension Relocate" feature is turned on. This means that when the phone is moved from one desk to another it retains the same extension number. To verify this do a Feature *0 and press the intercom button to view your extension. Now move the phone to another desk and repeat the process.
Passwords are related to the voice mailbox and there are verbal commands using the dial pad to make any changes. Usually 1 is for yes and two for no or 1 to change and 2 to accept. Not knowing which voice mail system your have it is hard to give anymore detail.

Our phone system crashed not to long ago and had to get new equipment we had someone come in and reprogram the phones. Everything was fixed except a few extension were switched around. so say the person at...

Go look at the system cabinet. The processor (the card with all the jacks in the center) are numbered. If it's an R8 card, then they number 10-18 from left to right and top to bottom. (actually 10-14 and 15-18) 13 and 17 are right next to each other :-)

It's fairly easy, you ought to be able to start moving jacks and figure it out.

How to move my ext# to a new phone location Nortel t7316E

The system has a built-in feature called "Set Relocation", which will allow you to move your phone to another active telephone jack in your office and the extension number, voicemail box, and all features will stay with your phone.

Have your system administrator turn on Set Relocation, or check your Norstar administration manual for programming details. Or, you can call your telecom service company and have them send a technician.

Not in service

Whoops, the second part of that is press FEATURE *0 and the intercom button before you move it and see what extension it is.
Do the same thing after you move it. It will tell you what extension it is and if it stayed the same.

The system CoOrdinator or installer can turn off that Auto Set Relocation feature :-)

Change/reprogram extensions

The easiest way to do this is move the cross connect in the closet. Get the jack number from each location and swapped the cross connect(wire). You could change the extension number in MB4-10 but it depends on the type of system you have.
