Dialing out of Filemaker

[hobbes-nz]

Hello there. I am wanting to set up Filemaker on Macs and PCs to dial out of the database to a ISDN telephone. This worked while we had version 4.0 and 4.1, but doesn't seem to anymore. We are using a Keyspan USB-> Serial adapter that plugs into a serial socket on the telephone. Anone in a similar situation? Cheers in advance!
