i have a avaya system placing in this order. 308EC, messaging system, and 509 proccessor. What I am trying to do is to access to the avaya system remotely but it not connecting properly. I follow the manual book but it doesnt work. So is there some sort of setting that i must do that is not mention in the book for me to access the avaya system remotely from a different location.? for remote auto attendant and thru auto dialing.
