The welltech epbx100 is a small IP PBX board.
It ship an Intel IXDPG425 Network Gateway Reference (IXP42X 533MHz) SoC.
Original image ran an old 2.4.31 but upgrading to recent kernel was
easy.
It misses a working network interfaces but its current state is
sufficient to work on my interest, its crypto device.
More information on the board could be found on http://kernel.montjoie.ovh/welltech-epbx100.html
