Thats your problem.  

I tried this too as an experiment and asterisk appears to take "all"
to mean "all codecs you can think of, not just the ones you have
converters for."

Instead of "all" you may want to try listing the codecs asterisk
actually has (this is from -current):

;
; codecs: a_mu adpcm alaw g726 gsm ilbc lpc10 ulaw
;
disallow=all
allow=ulaw
allow=alaw
allow=gsm
allow=adpcm
allow=g726
allow=ilbc
;; allow=lpc10  (robotman)
