[Asterisk-Users] Digium X100P vs Dodgy Ebay X100P

[Chris Stenton]

This is a digium list so I'm not going to promote other clone cards but I
will say there are cards out there that are much closer match to the digium
but probably have not gone through the regulatory european certification
procedure which the digium cards have been through.
