I have tried Billion HFC-PCI and Eicon Diva cards for ISDN 2e in the UK but both seem to have drawbacks/advantages. I need to build a new Asterisk box for my tiny business (1 x ISDN2e from BT and 1 x IAX link from Gradwell) Is anyone prepared to go out on a limb and say which card they prefer and why? TIA Simon
