You right, may be is way over of my head.
But also I know KYYS is not voice mail, I am trying to activate the built in auto attendant (may be I am wrong).
Currently the Incomming call goes to VM 990 and 991 as bunnie mention. I could get into the mailbox 990 and 991, but I can not change the button assignment from the menu option such as; 2 for sale, 3 for support etc.
I thought I could use Program 09 for the menu prompt assignment, but it doesn't change the button on the menu option. From the Programming guide read the program 09 will work if I have the Build in Auto Attendant activate, which is need KYYS chip. So I tried to add KYYS and reconfigure the works if use, thats was my understanding.
My main goal as novice is to change the button assignment for the menu prompt that recorded through mailbox 990 and 991.
It would amazing for if I could do it by my self as a learning. But if everyone said that to much for me, I would thinking to call cert tech.

Thank you.
