Wow. While this is absolutely not what I wanted to hear, I'm really happy that I've finally got an answer to this question. Thank you. I don't know how and where you found that information, but I'd like to know about the TDMx0B family too: are they capable of creating line voltage reversal. Could you just perhaps find out for us, or provide me with pointer how to figure it out myself? > There is another chipset in the same family that supports full > international operation.

From the lists it is obvious that there is a lot of interest for their hardware outside the US/Japan market. Same goes for the rumoured 4port fxo cards, of course. wkr, -- Envida http://www.envida.net/ Armand A.
