IP Telephony FAQ's:
Why are there two versions
of the G.711 CODEC?
This goes back to the development of digitized voice by the phone
companies. The U.S. and Japan have standardized on G.711 mu-law.
The European standard is G.711 a-law. They use slightly different
coding schemes.
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.
