Hi i am using Avaya Voice Annoucement over LAN Manager to administer my val board but i am not getting informatio at all, get a message that says
NO VAL BOARDs Detected on Cuervo (cuervo is the name of my switch)
I am connecting directly to my switch just like when i use ASA, wonder if i have to use a C-lan to connect or if i have to setup something else on my VAL because ti is not detecting anything at all

here is the the equiptmen information, thanks
