Hi,

i am having an issue with a phone in our current system. we have the NEC SL1100 installed with 3 extensions, two of the extensions are working fine but the third extension has no power

i have checked all cables and all are fine i have even swapped the wiring over and the extension in question illuminates if conected to one of the other extensions wiring.

i have a analouge line that operates three extesions

i expect there is an option in the cabinet that needs turning on in order to restore the service to the extension but not sure

hope someone can help been trying to fix this issue for over a week.
