IP Telephony FAQ's:
What CODEC has the highest
voice quality?
The venerable G.711 was developed for the T-carrier digital trunking
system and offers uncompressed digitized voice with the best quality.
The tradeoff is that G.711 needs more bandwidth per conversation
than CODECs that compress the voice signal.
What is the advantage of
the G.729 CODEC?
G.729 is a CODEC that compress the digitized voice signal to transmit
phone calls using much lower bandwidth than the standard G.711
CODEC. The tradeoff is a reduction in voice quality compared to
uncompressed voice, but quite acceptable to many users.
