Turn the ringer on for external calls.

Go into the extension programming and change the line settings to no ring. It is best done if you have a display phone so you can see the changes. If not, then you will need to look at the flashing line lights when you enter the programming mode.

Press Feature 00. This will take you into the programming mode. You should see the line buttons lit up green. They will be Solid (Immediate Ring) or Slow Flash (Delayed Ring) or Fast Flash (No Ring). I assume yours is solid so push each line button until it changes to a fast flash. Once done press Feature 00 to exit the system and save the settings.

Here some solutions for your problem + a link to the user manual.

**Selecting the Ring Tone and Volume
Your phone has five different ringer tone/volume combinations you can choose from.
To select the ringer:
1) With the phone in standby, press [vol/ / ] or [vol/ / ].
2) The phone will sound the different ring tones at different volumes. To turn the ringer
off, select RINGER OFF.
3) When the phone sounds the ring tone and volume you wish to use, press [end].


**Temporarily Mute Ringer
If the handset is off the base while an incoming call is ringing, simply press [end] to mute
the incoming ring. The ringer will sound with the next incoming call.
Note: You can only mute the handset ringer if the handset is off the base when the phone starts
ringing.

If you use strata emanager it would depend on how your system was set up. One way is to go to Advanced configuration tab Station tab, multiple call group tab, click on the group number (far right), then member tab and select extention and ringing option. Another way is to go again from the advance configuration tab, then assignment tab select the extention number on the right select key assignment tab, and on the incoming extention line double click it nd select no ring.

firstly read the operations manual for that phone look on how to adjust the settings of your phone it probably sure was indicated there, because the way i see from what you posted it has no internal circuitry prob. it just needed an adjustment.. hope this advice helps... ;-)

The volume control adjusts the handset, hands free, headset, and ringer volume. Someone may have fiddled with the buttons and turned the ringer down enough that it doesn't sound when a call is incoming.

goto the name and hit store it will restore the name and when going threw the store process it should show you old parameters
or goto phonebook find name and edit its preferences for that name phone ringers are set ringers so when you pick one for gereral use thats going to be the general use ringer but special ringers is what i descriped in first part
menu handset setup then ringers for a general ringer you can change to a more pleasing ringer but over all cant turn off

How do you want to be notified? How do you determine if a call is for you? Does an operator answer the call and transfer it to your extension? If so, you just need to change programming for your phone so it does not ring for incoming calls. It would still ring if a call is transfered to you. Programming is changed in the phone system, not the telephone. Your phone can be used on different Nortel systems that program differently so you need to find out which system you have and locate the manual for that or pay a local installation company to make the changes.

try turning ringer speaker volume down. if that does not work, then remove battery for 10-15 minutes and replace and try again.
