I’m planning a system that will eventually have three TDM400P cards (6-8 ports for the incoming analog lines and the remainder to support legacy analog phones). I’ve read over the Digium configuring_zaptel.pdf doc, but I’m still not sure how to configure this. Obviously, I need to have each port on each card assigned to the same channel each time the system starts up. Can anyone help?
Not for sure how to set it up but beleive I would look at a t1 card with a channel bank. I have read were people have used up to 4 cards without problems but a lot of the time people run into interrupt problems.
