OK, that looks fine.

It's always possible that the problem is a misconfiguration at the remote
end. I had that once, where the PBX to which Asterisk was talking had had
its channel numbers misconfigured, resulting in a similar problem to what
you have described.

What happens if you swap the cables over between the two E1 ports on the card?
Does the problem move to the second card (channels 32-46)?
