We have two 7965 both with 7916 modules. The lines on the 7965 are not identical, but the lines on the 7916 are.
When a call comes into one of the 7916 lines the line will flash on one of the 7916s, but not the other. The one that does not flash as the call is ringing will only light up once the call is picked up by any other phone with that line configured.
Any idea what would cause the lines on the 7916 not to flash when incoming call rings?
