Do you know how to get into phone system programming? The extension names are changed in there.

I'm working on the same issue. I use to have paperwork on how to do this - but I can't find it now. Have you been able to solve it?

the access code is the number you dial to access an outside line like 9 or 81 etc.
To program a button to access a certain line pool, press feature *3 press the button you want to be the line pool access button then press feature 64 and the pool access code. ex. feature 649 or feature 6481

Could be two things, there could be a general delivery mailbox attached to the system which is mail box 100, or the new service provider has a off premisis voicemail attached to the lines. if there is VM on the lines you should get a stuttered dial tone on the line indicating that you have a voice mail.

There is no power cord required for an M7310 set. The set gets all the power from the Nortel telephone system. Try plugging in your phone where another phone is active to ensure that your phone that you want to install is working. The phone flashes, then stops, then flashes, then stops... you just have to be patient when testing. Possible Troubles: -> It maybe the line cord, the cord that plugs in from the wall to the phone that can be damaged. -> the jack might be dead (wiring in the jack is pulled off) or inactive (there is no jumper from the office to the telephone system). -> the phone port from the telephone system might be dead.

Here you go, this is the user manual for that phone system, with everything you will need
