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.

Line connection


try this;

press sp-phone enter *71029, then enter the outside number, then #, you will hear a tone that means call forwarding is activated.
to cancel press sp-phone *7100# or simply dial 790 for extension data clear

Landline phone constant busy signal


should you dial 9 or another access code for outside calls?

If if you dial an "outside" number on an intercom line it will look at the first 2-3 digits as another extension. You need to dial the Central Office access code, or use a line key assigned to an outside line.

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.

Every extention on the console is showing with the red led light, as if the lines are busy. Therefore I cannot transfer calls, when in actual fact, the lines are not busy


ouch, sounds bad...
possibilities~
1) everyone has DND turned on if so have them disable their call forwarding entirely (intercom*7100)

2) your buttons are all suddenly programmed wrong, reprogram them to the correct extensions
(press "PROG" then the button you want to program, press " 1 " then the extension number, then enter)

3) major error with the system, have a serviceman come out and take a look

I bught a kx-ta824, I just have one CO line and i want to put 4 extensions , but i couldn't. I can just recive 1 call and then the line sounds busy.


With one CO line you can only make or receive one external call at a time. You can have extensions connected on intercom calls, but once your CO line is in use, anyone calling in will get a busy signal, as will anyone in the office trying to make an outside call. You'll need additional CO lines if you want to have several outside calls going on at once.

Multi line system and phone still rings while I'm on another line


courtney,

Unfortunately if the receptionist is using priority call (f69) there's not much you can do. Priority call is an administrator programmed function that overrides when your on a call and when the set is in do not disturb. Maybe bribing the receptionist might be in order.

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.

Internal intercom


If the person you are trying to reach is speaking to another internal extension, none of the outside lines will show in use. If their phone is not Call-Forwarded to any other extension (i.e. second extension or VM), you will get a busy.
