Developing a capi application from scratch is very difficult so i would use
one of the various capi software development kits,
e.g. ftp://ftp.avm.de/develper/capi-adk .

You have to connect in transparent protocol mode,
i.e. B1=1 B2=1 B3=0. You need your audio data in A-Law format with 8 kHz
sampling rate. There is a audio conversion tool named sox wich can be used
to convert your data. Probably you have to swap your bytes to network
ordering.
