uLaw *is* telephone quality. Its what the PSTN uses. G.729 is much 
inferior, but at 1/8th the size (not 1/3rd unless you count all the RTP 
overhead). Its a trade-off. If you can't hear the difference, see a 
nurse and get the wax out of your ears :-)

G.729 is OK in a quite room. If there is a lot of background noise it is 
awful. Might that explain the difference in perception?
