Zumbo,
1. most probably you are seeing the AVM modem devices
provided by the "AVM Capi Port Driver". This driver is not
capable of providing audio support.
You need to install either
- AVM TAPI Services for CAPI or
- ComISDN TSP (www.comisdn.com)
2. To route audio to your sound card you can either use TAPI 3.x
which makes this very easy (just select the default static terminals
on the audio streams
With TAPI2.x you need to use low level wave api to copy
audio data between the soundcard and the audio devices provided
by the TSP.
Best regards,
Matthias Moetje

I'm writing an application which should be able to make phone calls via
the sound card (which is noth physically connected to the modem). My
modem is a AVM ISDN Controller (FRITZ!Card USB v2.1) and I'm using TAPI
2.2. The modem clearly *is* capable of routing the voice via sound
card, since with the FRITZ!fon application, I can make this kind of
call.
I'm not sure how to build this functionality into my own app. Earlier
comments in this group sound quite discouraging. Is TAPI the right way
to go?
In my device list, I have several entries for AVM ISDN, but all of them
only support LINEMEDIAMODE_INTERACTIVEVOICE, but not
LINEMEDIAMODE_AUTOMATEDVOICE. And when I try to make a call with them,
I get the "Lift the receiver and click Talk" message, which according
to http://tapifaq.pennypacker.org/tapifaq6.html#QVI-9 means that the
modem doesn't support voice calls. When I restrict the devices to
LINEMEDIAMODE_AUTOMATEDVOICE, I only get the IPCONF and the H323 line.
