Then you'll be happy to know that most VoIP phones default to and good VoIP providers gladly support G.711, the exact 
same codec used in all digital trunks in the POTS network.  Also, an on-the-ball VoIP carrier will be pushing G.722 "HD 
Voice" devices which offer about double the audio bandwidth in the same data bandwidth (64kbit/sec/stream) as G.711.

If your carrier is forcing G.729 or GSM, they're a joke.

I doubt the g729 or GSM codecs used by VoIP and Cell phones can compare to a POTS line.
