Does anyone know of a hardware adapter that can take ISDN BRI frames (I.430) and encapsulate them in Ethernet (any form, but TDMoE would be really cool), in much the same way that the redfone does for PRI? (yes I have asked this before in looser terms, but it was a while ago :) Would anyone find such a device useful? Thanks James
I also want to know this. This would be very useful in Call center for remote attendent. The E1 gateway will do this very well, but where is the BRI voip gateway?

PRI is primary rate ISDN, consisting of (normally) 30 channels or (rarely - US only I think) 24 channels. BRI is basic rate ISDN, and consists of 2 channels. They are not the same thing. The redfone is a PRI to TDMoE converter, I'm after something that does the same thing for BRI.

A SBC with built in Ethernet and a minipci slot might do, but a dedicated device should be able to be mass produced pretty cheaply though (~$100 range). The other problem I have is the lack of cheap ISDN adapters in Australia. I have only found 1 4HFC adapter here and couldn't make it work properly. Thanks James

If I unplug one of them then the PBX knows not to use it for outgoing (eg when I hit 0 to get an outside line, it doesn't select the one that has no L1). Incoming calls are also not affected. The only change is that now I have 4 incoming lines instead of 6. So I guess the telco equipment knows how to handle a line down condition. If you really need that sort of level of failover then purchase some extra redundancy in terms of incoming lines. Probably cheaper than any other elaborate setup. Do respond if I've misunderstood though :) James
