I am running CME 4.1 with CUE 2.3. When a message is left for an extension, the MWI envelope indicator appears for the extension, but the MWI light does not light. When I dial the MWI on number, the envelope appears, but no light. When I dial the MWI off number, the envelope disappears. I have double-checked my configuration on the CME. I will attach a copy of the configuration. Help!
