Meridian M7310; just installed replacement phone (used); line 3 disconnects when answered. Lines 1 and 2 work fine. They are in the loop. Line 3 is dedicated fax incoming but can be used as outgoing phone.

Check your button programming using Feature *0 to see if the lines are programmed to your phone.

If you only have one line,why not just lose the Nortel system? You can reuse the wiring from the phone sets to the contoller as regular inside wire,and just plug in regular phones(and maybe put the Nortel phones and controller on EBay and make a few bucks off it!)

Call a tech in that handles the system programming to check the line port if ok and/or call your carrier to report the line as being dead.

Programming is done on M7310, M7324 and T7316 sets.
To set up line appearence you need to enter programming by pressing the feature key followed by **266344.When prompted to enter the password enter 266344.
The screen should say TERMINALS&SETS. The 4 top line/feature keys are now used for programming.
At the terminals&sets prompt,
press the show key (top right arrow).
The display should now ask for an extension number. Enter extension number you wish to program the new lines on.
Press the show key (top right arrow)
The display should sat LINE ACCESS
Press the show key (top right arrow) .
The display should say LINE ASSIGNMENT.
Press the show key (top right arrow) .
The display ask for a line number. press list
The display should say line 001: appear & ring
press the next key (bottom right arrow) till it says 003:unaaign.
press the chng key till the screen says appear&ring
Press the next key(bottom right arrow)
The display should say line 004: unassign
press the chng key til the screen says appear&ring
press the Rls key when finished

You need to unplug something, just not the phone.

The two lines are probably conferenced together. Go find the gray Nortel cabinet and pull the plug on it.

Carl

you can divert calls from lines using line redirection (feature 84) however, it will divert all calls comming in on that line and not the calls going to the phone itsself

You have to remove line 4 from appearing on all of your phones.
Login to your system with Feature ** config.
Go to extensions find lines configuration, and set Line004 not in service on EACH extension.

the easist way to reset that is to reset the system. unplug it for a moment that should clear it.

This should work on M7310, M7324 & T7316

Feature ** 266344 - password 266344 - configuration - line data - line access - show ext (yours) - line assignment ( which lines you have, usually 1 & 2) - show line - appear only/ring/apprear and ring

Hope this helps

Do you have any programming experience on your system ? Is seems like the line has to be asigned to the phone it is ringing on but you will have to do that in system programming.
