I am looking to find out what the short code is to Activate/Deactivate the Massage Lamp in the IP Office..and can it be changed. I am trying to link an IPO/S8100/and voicemail (Objectworld) utilizing centralized voicemail. The code in vm 180 to activate and 181 to deactivate the lamps on the definity. Can this be changed on the IPO to reflect those codes?
