Verify that your VOIP phone is still plugged into a POE (Power over ethernet) port. If it is, verify the integrity of your network line. If for any reason your line is damaged (like dropping some gear on it, shutting it in a connex door, leg of your cot pinching it, or even your IMO got confused and snipped the line. Definitely check layer 1 which is your physical line, and the switch it plugs into. Check your ends also, if you have crappy crimp jobs on your RJ45 ends you might be in trouble. See if you cant score some CAT6 cable from the commo guys. That'll help.

Hope your phone is back up soon. Good luck, be safe, the Military is a small world and I might see you around. ;-)

After power outage incoming calls cause all lines to light up


If this is happening on the entire system, then make sure you have the number of lines programmed correctly. If this is correct you may have a bad processor card. If this is a happening on an extension only, then the port/card may be damaged I would temporarily move the extension to another port on a different card and see if the trouble follows. If it does you have an issue with the phone not the port/card.

WE HAD A POWER OUTAGE.NOW MY KEURIG WONT TURN ON. CAN YOU TELL ME WHAT THE PROBLEM IS. THANK YOU.


Hi,first you need to check if fuse has not been blown out.Because when POWER comes back after an outage there is a surge voltage flowing through electrical lines.It is advisable that when their is a POWER outage you have to turn off your FUSE box or SAFETY box to make sure that it won'tdamage appliances when POWER comes back>Technically when POWER SOURCE or SUPPLY has been shut off for a period of time.When POWER is back, expectantly there is an abnormal flow of current/line; current will not be as stable until a period of time..AC current behaves like a wave,values changes from time to time especially when POWER SOURCE has just been TURNED ON..So better turn off FUSE BOX when experiencing POWER OUTAGE so that when power comes back SURGE VOLTAGE wont flow within the circuit>Hope this helps..

Power outage now you have to select a line manually instead of just picking up phone and it's taking awhile before it starts ringing


What usually happens after a power outage is the system defaults because the backup battery in the memory card is dead. That means 2 lines only on every phone, pulse dialing, and all phones ring. If your system looks like that, it's time to call the Nortel repair tech. He can replace the battery or software module with a new one and reprogram the system.

We seemed to have a power outage over the weekend. We have M7324 system with 6 rollover lines, only the first two work now, the other four are not working. I rebooted the system, no change. Can you help?


You must have an older system. There is a battery built into the control unit (not user replaceable) that stores the system programming in case of a power outage. When the battery is dead, your system will lose all programming and default to assigning the first 2 lines to all phones. The system will have to be completely reprogrammed.
Please Note: Now would be a good time to install a UPS/Battery Backup unit on the phone system. I recommend a large enough unit to keep the phones running for at minimum of 2 hours during a power outage. Install the UPS/BB first, and then reprogram the system (so it won't have to be reprogrammed twice). Good Luck!

Since power outage phone lines do not ring - only to receptionist


Your system lost its programming. It will need to be reprogrammed completely. The lines are ringing on the extensions where I voicemail is, unplug voicemail and at least lines will ring in correctly.

The battery is dead and will not maintain system programing after a power outage. If the battery is not replaced this problem will occur everytime the power goes out.
