If you're looking for a cheap passive ISDN-card for FreeBSD-5/6, there is the
HFC based devices:
AcerISDN P10
Asuscom ISDNLink P-IN100-ST-D2
Bewan ISDN USB TA
Bewan Modem RNIS USB
Billion ISDN tiny USB modem
Billion USB TA 2
DrayTec ISDN USB
DrayTek USB ISDN TA (MiniVigor)
HFC-2BDS0 ISA/PnP/PCI/USB ISDN
Motorola MC145575
OliTec ISDN USB
OliTec Modem RNIS USB V2
Stollmann USB TA
Teles S0/16.3c PnP
Telewell
Trust ISDN
Twister ISDN TA
Xplorer 500
Zoltrix Speedier 128K PCI
I checked out "www.asterix.org" and couldn't find that it supported ISDN4BSD.
The problem is that I4B has a delay of 256ms per direction for sound-data,
though that can be tweaked to 50ms by changing the drivers. You will get best
results if the sound is bridged in hardware and not software.
Emergency calls over VOIP is problematic. Have you considered network power
failures and software crashes?
