Rubbish. That Dialogic card is designed and approved for use with PSTN 
lines. The only Dialogic cards I know of which are purely PBX oriented 
are their MSI cards, which only *provide* 24V and a lowish ring voltage.

That said, the D/4PCI is useless with *, even if you buy the drivers. It 
is not a full duplex cards. The * drivers are for the JCT cards.
