Well, that's all there is :-(

If I remember correctly what you're talking about, that's just the
way it is.  Voice code in modems is optimized for telephone lines and
*low data throughput*.  So 9600 samples/sec. is a fairly reasonable
value (ELSA uses 7200, for example, which also sounds pretty well) - the
quality you can achieve with 9600 samples/sec. is good enough for a
telephone line.

You might want to use ADPCM-4 for best results (pvftormd ZyXEL 4 ...).
