Hi my name is ***** ***** I may be able to assist. Have you tried dialing the VM box and entering *999#, then enter the security code e 999997 or 8888 followed by #? Let me know if that works for you.
Sorry, I got stuck on another call. I'm going to open this up to the other experts and see if they can help. I was not able to find anything.
We used to have the same system- as it is end on life on limited support I would suggest speaking to nortel but it is unlikely we could gain access as each system has a different SID Identifier.
Not the answer your looking for I know.
