Hi,
I'm looking for two types of PC cards (PCI or ISA) that
would let me experiment with computer telephony.
First card should have one or two RJ11 interfaces to let me attach
POTS phones and have sets of APIs that would let me
generate dial tone, power ringing, interpret DTMF and
detect on-hook, off-hook and flash and somehow intercept
PCM samples (from the phone).
Second card should let me connect to PSTN through
a plain phone line (RJ11) and support all functions that
a POTS phone has (i.e. from PSTN it would look like a phone set).

I would appreciate any help finding such cards.
Thanks,

The first card you want is the Internet PhoneJACK. The second is the
Internet LineJACK. They do exactly what you want, and sdk information is
available for Win32 and Linux.
Fair disclainer - I work for them :)
