you can use a laptop to do it, but will need WINSPM software to do it. will have to purchase it from avaya or bus partner. much easier that way then through a phone.
can also do programming from am MLX-20 phone that is attached to certain ports, usually the very first port on the system. jsut have to hit the 'menu' button on the phone, then 'system program', then 'start' and you are there.
thanks, tim
