It is, and is identified by wcfxo as "a Wildcard FXO: Wildcard
X100P". So much for "The DigitNetworks X100P is detected as an
actual X101P card."
IIRC, there were 2 Digium single FXO cards - the X100P using the
Motorola SM56 and the X101P with Intel/Ambient 537. The X101Ps have 2
RJ-11 jacks. Functionally, they're all Winmodems - effectively just
DAAs connected to the PCI bus. The Zaptel driver is responsible for
the caller ID and DTMF detection. Maybe you have a borked card or it
could be due to impedance mismatch. I know that the X101P only works
with FCC 600 Ohm impedance. For other parts of the world, YMMV.

Is DTMF pass-through and caller ID fundamentally different? This card
does not seem to cause significant difficulty in DTMF detection. The
high DC voltage
As I mentioned all the DSP work is done in software. So there shouldn't
be any fundamental difference.
during ringing could be one factor. Any easy way to test serious
mismatch? The 600 Ohm is actually on-hook resistance, right? Or is
this audio impedance? The
600 Ohm is off-hook AC impedance for US and countries that follow the
same specs - consult your local regulatory docs.
card is indeed sold and used in North America.
But, where in the world are you using it?
