BTW, I forgot to mention the built in ISDN ports in some of my Sun kit - SS10 and SS20, I think.

If I understand correctly, the equipment mentioned above will still require some sort of dedicated hookup to a telco provider in order to transport packets between two local devices. We don't have that and we don't need/want to get it (we have POTS service and DSL over POTS).

I was/am just looking for a simple solution for interconnecting my packratted ISDN devices for some testing and fooling around, like room-to-room intercom, using ISDN between computers (like a slow-speed LAN) or playing back audio from a computer through an ISDN phone.

Thanks for your suggestions anyway...
