To prove circuit is okay you need to swap phones

It probably is the phone extension line (from the wall)
to the phone.

Again you need to test phones using a known working phone cord. When you rule out the circuit and line cord then you can only point to the phone itself or the demarc point.

Why made phone early now cant just get busy signals?


Sounds like your phone or line is now short circuit and is holding the line so it appears busy to incoming callers. Try disconnecting the pnone and line right up to the incoming point of your house to find the problem.

I have put a main greeting on my Norstar M7310 phone for all 5 incoming lines, however one of our incoming lines has grabbed a personal message form another extension and callers get that personal message...


You need to know what extension is causing the forward directly to voice mail. Chances are that this extension has ringing lines programmed to it and the forward on busy is to voice mail. ANY PHONE THAT HAS RINGING LINES SHOULD NOT BE SET TO FORWARD ON BUSY. If they happen to be on the phone when a call comes in it will go straight to their personal mailbox.

NEC Dterm80 phone, Model DTH-16D-2. We have an Extension that rings as a back-up to the main attendent/receptionist in the event she cannot answer an incoming call. I need to disable the incoming ring at...


Hi if you just want to silence the actual unit, most often you will find a small switch on the unit, that switches OFF the ringer, or often one can turn it down, via a control on the unit. Other times one can set it Off or down in volume via the settings, use the manual in these case to ascertain what to do.

Above is a manual so you can check exactly what and how to do what you want.

If this cannot be done, then take the phones case OFF, locate the "Ringer" and disconnect it from the board, problem solved.

My phones only light up on my panassonic business phones


If you have a PTPM or the maintenance console, you can program ringing. It's a dealer only product in the U.S. Incoming calls are made to ring ICD (incoming call distribution) groups where the ringing is controlled per extension. In our version, even the manager does not have access to that level of system programming.

Tc not work in my pc


Hi Shashi,
please make sure the TC files are extracted in following folders after installation

c:\tc\bin --> all executable files
c:\\tc\include --> all header files with .h extension
c:\tc\lib --> all library files
c:\tc\obj --> all .obj files copy them to c:\tc\bin too

now goto my computer --> c:\tc\bin
copy tc.exe file and right click on desktop and select copy short cut and press enter

Now you can start TC simply doubleclicking this shortcut icon

Please call if having any problem

Can not pick up line on incoming calls from one extension only


That's what happens when you plug in the system and don't program it. You need to review ICD groups.

By default, the phone connected to the first extension is the master phone and the only phone that rings.

Transfering calls


It sounds like your dealer didn't properly set up incoming call distribution groups. They probably just gave you the "default" settings and left you a manual, took the check and said, "Good bye, and good luck!"

I think you mean transfer instead of forward. Your incoming calls should go through an Incoming Call Group - even if you're the only person in the group. Then you can handle the calls as they come in, transfer them out, and if you run out of buttons the system can even queue the calls up until you can get to them.

We have a support package that allows us to make all the changes you need over the Internet for a flat annual fee. If you want your whole system to work properly and all changes to be made for you at a flat budget, call us at 877-236-8376.
