> Are you using the .gsm codec or some other flavor (ulaw, alaw, G729?)

 

This is from the sip.conf for the provider: 

allow=gsm

allow=ulaw

 

This is from the sip extension:-

alaw,ulaw,gsm

 

Based on this, your call is probably getting to the provider as ulaw (the
alaw is thrown out since it isn't in both selections; if you are in U.S. you
don't need the alaw).  Try the call with higher debug (at least 5) and
verify which one is being selected.
