8khz is not the best sampling rate, but that is the best you can do on the PSTN. HOWEVER, you should be able to get fairly decent sound qualify out of an 8khz sound file on the phone line. We have our IVR recorded at 8khz and it sounds fine. Are you using any compression, or G711u/PSTN for your trunks/phones?
