Can anyone recommend a good vendor that provide a PCI PRI ISDN card
and the complete stack itself to kick start our ISDN project ? The PC
is running on Win NT4/2000. We have check out a few. But none have a
PCI design running on WinNT and/or are willing to sell. Preferably the
board contains DSPs to detect DTMF or call progress tones. Most of
them do not support this and therefore most likely we need to modify
their existing design. Any recommendations are welcomed.
