[Asterisk-Users] SysMaster and GPL Violation

[Francois Menard (Mailing List Account)]

Do you know what hardware is Sysmaster using as a TDM interface?  Is it 
relying on Asterisk to perform host based processing? If so, I would not 
be surprised that if they are OEMming lots of Digium boards, there is no 
wonder here why Digium keeps it cool, if not, well...
