Which would suggest the ring-detection function on the chipset took a dump.

I started with a TDM04b about a week before they were announced as generally
available, and the early versions did have problems (as did the drivers).

I have two production servers that are now using the TDM04b, and both have
good uptimes. One is rev H and the other rev I.

For the price, there isn't anything else on the market. However, there are
several fxo gateways that operate very well at a higher cost.
