I'm trying to add a new phone to my system. It's going to be superset 4025 digital phone. I'm trying to add it to a free PLID. The extension I'm trying to add is currently used for a voicemail, I just want to add a phone to the users/voicemail extension.
If I run maint. command locate extension my return is LOCATE: Non Prime extension number, which is what I believe indicates that it is a voicemail.
I'm guessing based on previous threads that the number could be used as a key somewhere else. Is there anyway to find out where the key is programmed on other extensions?
