This is a function of your modem - use one of the modems suggested on the NCH site.
I doubt very much that the card ist the problem because other voice applications work perfectly well with this card and its TAPI drivers.
Besides, the AVM cards have a very good reputation among consumer grade ISDN cards and this would be the first time they were causing trouble that I ever heard of in years.
You could possibly correct the problem if your modem handles 8 bit ADPCM format
choppy recordings
in IVM

Is there a utility I can test this with?
