Richard,

what codec are you using?

I get good results on MacOS X (client side) with the ulaw codec.

On my sip.conf side I do first disable all codecs; then I enable ulaw and
alaw. On the x-lite side I do actually select G711u as the chosen codec.

PS:

--- from : sip.conf  ----

disallow = all             			; Disallow all codecs

allow=ulaw 
allow=alaw
allow=gsm                  ; GSM consumes far less bandwidth than ulaw
