I don't think there would be any point (that is to say, any quality
improvement) in recording at anything other than 8KHz at present,
since all audio passing through Asterisk is sampled at 8KHz anyway. If
you need 32KHz files for compatibility with another application, it
should be fairly trivial to upsample the recorded files using a
utility such as sox.
