I have a Nortel phone system - most of the phones are model M7310 - I have another phone model M7208 that I have put into place. I can dial out on it, I can dial an existing extension from it, but when I try to dial it's extension, I get the message 'Not in Service'. How do I put this phone into service?

Dear Sue Johnson

Right, well immediately you have given me a symptom of a fault with the LCD (Liquid Crystal Diode display), and my guess is that if the display is not liquid induced or that it is not broken, then the only thing left to rule rule out is power failure to that part of the circuitry. Now i would have tothoroughly investigate why this happened before i could pinpoint exactly what the fault is, but a good guess would be either bad refurbishment, or liquid induction/ ingression previously has damaged components.

Now about the extension problem, I wouldstart off by stating that the refurbed portion of the system may have malfunctioned again or even elsewhere on the device, which may or may not have been directly caused by refurbishing involvement.

Im guessing that either your switchboard controller is faulty, or possibly a fault somewhere in the switching equipment that is in direct relation to data transfer over the RJ45 connectors (standard phone/ network cable type connection)

Your best bet is to remove all of the phones on the extension/ switchboard and then install them one-by-one and see what errors are thrown up, the ones that cause you a problem and then tackle the switchboard with the direct fault.

If all of this is to do with the phone (s) and not the switchboard, then i would say, remove the phones, replace them with a similar type and then notify someone like myself who may be able to advice you on your next best course of action. But if yor phone network is that valuable, then i strongly suggest selling the broken phones for spares / repairs and using the money to at least cover part of the cost of purchasing new ones of the same make and model as the ones on the rest of your local system.

The same will obviously apply to the switchboard, unless there are user servicable components inside, or you are particularly handy with electronics, comms technology and a soldering iron.

In the mean time, I wish you all of the best luck, and I hope to hear more about this situation soon, I also look forward to helping you the best i can with regards to this matter.

Yours sincerely

oz

SOURCE: Program a new Nortel m7310 phone with an existing extension

If the extension was a swap of the old M7310 with a new(ish) M7310 no additional programming should be necessary. However if the phone was replaced with another type of nortel set(M7208, M7324,T7313 etc.) then the phone will default to its base features. To re-program the feature keys press feature *3, the button you wish to program, and the feature code for that button

SOURCE: Nortel M7310 Phone moved to another jack, now no incoming calls

The reason your phones config is not the same as before is because configuration goes by what extension it is. So if you plug your phone in somewhere else, unless you have DN's configured, your extension changes, so say it was extension 21, but now that you moved it, its now 23, those settings remain on extention 21, so if you bought another phone and plugged it into were extention 21 is, it would have the settings that your old phone had before

To access the intercom by just picking up the handset, Press Feature **CONFIG (266344), Select <A. Configuration>, then go to <2. Line Access>, Select that and enter the extension of the phone you want to have access intercom by just picking up the handset. Scroll until you see <Intercom Keys: #,> make sure you have at least one intercom key. Then scroll until you see <Prime Line: #>, Press change until the display reads <Prime Line:I/C>  And there you go. Hope i didn't confuse you

There is a built-in feature called Set Relocation. Check with your system administrator to make sure this feature is set to No. Then you can swap phones without a problem. Good Luck!
