Hello Asterisk Community! There have been some complaints made by those customers that purchased the TDM400P board and it didn't work properly in their boxes. Digium promised to swap such boards for the new - revised version and will keep the promise. However since we were backordered we're currently shipping boards to the customers that paid and are waiting. But if you want to receive your new board *very soon* you can call Greg or Malcolm at 256-428-6262 and ask them to ship you the board along with the new orders. If you're not in a hurry we will proceed soon with the list of people that reported the problems with their TDM400Ps before. regards Martin
