I personally decided against using PCI(e) ISDN BRI cards. Eicon and
various AVM cards all had problems with echo cancelling. I'd suggest
using external SIP gateways like Vegastream or SmartNodes. Easy to
configure (once you figure out how with a SmartNode), good quality and
much easier in failover (though might be a single point of failure by
itself).
