WHY MY PHONE WONT RING AT MY STATION - NEC Electra Elite DTU 16D-2 Corded Phone

You said "it seems to ring once then stops." One possible cause of what you're describing is called a "Ring Trip." It is characterized when the button that flashes to indicate an incoming call changes to steady red (which would normally indicate the call is answered) although no one actually answered the call. If that occurs, then you have to test to see whether you can tell where the problem is coming from. If you unplug all the phones, you can then call in (from a cell phone or other phone that's not part of the system) and see if the incoming call rings unanswered, as it should when no phones are attached. If all rings in OK, plug just one phone in at a time and call in to see if any particular phone causes the problem. If one causes the ring trip, then disconnect that broken phone. If ringing still stops when no phones are attached, you'll have to disconnect the phones' connection wires (Station Wires) at the phone system box that plug into the "Station Ports" (label them before you unplug any!). Do not unplug the plugs for the wires that feed phone company lines into the phone system, the jacks are called CO line ports. With the "Station" wires unplugged, see if If all rings in OK by calling in from a cell phone or other phone that's not part of the system. If all rings in OK, plug just one station wire in at a time to see if one causes the problem. If one station wire causes the ring trip, then disconnect that troublesome wire and inspect its "system box jack" and its phone jack for water damage, carpet cleaning solvent, exterminator spray or any other corrosive liquid damage. Sometimes a staple through a wire where there's humidity can cause the problem. This process will find the offending wire, jack or phone that causes a "Ring Trip." There are many other possibilities, but the extremely limited description you've provided "it seems to ring once then stops." doesn't help me send you a better answer yet.

if you know your password for your phone system do this. enter programming mode by pressing transfer key, type 800 enter your password then volume up key then speaker key. go to program 601 station groups find unused station group ie 510. make this group unconditional and under members add all thr extensions you want to ring then press speaker key. then go to program 406. enter line number of line and under night mode tell it the station group number you programmed above

I had the same problem - faulty mains power supply to primary base station (where the BT line connects)

You must go into CO line programming and put that station into the ring assignments for each outside line you want to ring at that station. It's Flash 40, page A, button 10.

this sounds like you are either out of range of the base unit or your base station isnt plugged into the mains, ensure you have the base station plugged into the power and the phone line from the wall socket is plugged in, the base station controls all the handsets, if it isnt plugged in they wont work, good luck

The extension is not programmed to ring. Re-program that station to ring.

There is only 3 beeps when you call the station because it is set in th privacy mode (HTP) on bottom of phone. Change it to T for tone. Any further, don't hesitate to ask. If this don't work, let me know.

Answer to the second problem :-

1. The changes in the ring tone has to be made by accessing the Avaya server where the phones are registered.
2. Log in to the avaya server...... enter change station <station number> on the command prompt
3. In the personalized ring pattern field, you can select one out of the 8 available options by typing any digit between from 1 to 8.

4. The ring pattern of that particular station will change accordingly.

5. Keep the personalized ring pattern of all the stations different by assigning different digits against this value

Sounds like your station (phone) is set to not ring. You need to check your ring assignment.
Feat # *
Enter password (default is 000000)
Press the soft key under "show"
Press the soft key under "next" until 1. STATION appears in the display.
Press the soft key under "show" SHOW STA:_ appears.
Enter your station number and press the show soft key
Press the "next" soft key until RING ASSIGNMENT shows on the display.
Press the "show" soft key. You will see CO LINE 1 : followed by NONE or DAY or NITE or BOTH.

If it says NONE, your phone never rings for an incoming call. If DAY or NIGHT your phone rings depending on the time of day and the time definitions for DAY and NIGHT programmed into the KEY unit. If it says BOTH, your phone should ring all the time.

If you need to change the setting, press the "chg" soft key until the desired setting comes up.
When you're done with LINE 1, press the "next" soft key to move to the next line. Repeat the process for all your active lines. Obvisously changing settings on lines with no CO connection will have no affect.

While your in the mode, check your RECEIVE ASSIGNM as well to make sure your phone is configured to receive incoming call. It was the station feature just before the RING ASSIGNMENT feature.

Hope this helps.

You have to get into your database programing "Feat, #, * " Says enter password, Default is 00000000. Enter into "Staion" then where it says "Show sta" enter 11,12 13 etc. "show" scrole to "CO Line Ring Assignment" Enter "Both" on each station you want to ring. Station #10 is the only default station that will ring without reprogaming the other ones to ring along with it. Hope this helps.
