Which part of the previous post did you not understand?

You wrote the entries in /etc/zaptel.conf "assuming" that what you are 
calling Board 1 really is Board 1, and its not. Its Board 3 using your 
numbering scheme.

I don't know of any way to determine exactly how three identical boards 
are numbered, so you'll have to experiment to determine which board 
holds channels 1-4, which has channels 5-8, and which has channels 9-12.

Its obvious from the error message that you posted that channel 9 and 10 
correspond to what you are calling Board 1 (since there are no modules 
in the first two positions of that board).

So, change your /etc/zaptel.conf and zapata.conf to address the empty 
channel 9 and 10 slots.

Once you get asterisk to run, then (and only then) you can place a call 
to each pstn line and see which Zap channel corresponds to which board 
by watching the CLI.
