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.
