Reviews

excellent card , 8/25/14
By PROMAX
What can I say... its a digium. Manufactured by the people that made asterisk. Pretty much plug and play with our asterisk applications and quality makes any old PC into a professional phone system. Echo cancellation is perfect for compensating any issues we have in the local area. Havent had a complaint yet from any of the installs.
