I changed a phone in an option 11. Key 0 was a scr key and I changed it to a cdn so that I can have it set up in symposium express. Anyways, now that the change took place whenever I have a voice mail, the message light does not light up on the phone (2616). My extension that used to be on key 0 is now on key 1 in the configuration. Is there a way to make the message light up whenever I get a message on my phone?
