Can you send me picture of the top right part of each of the voice board ? I want to see if they do not share the same ID. Here is the reason :
Each voice board had his own id. This id is set with a strap. So when you swap the board, you didn't swap anything since each board kept his previous ID.?
Dang! That means that there is something wrong with the voice card.
OK, thanks, closer to the problem now.
