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.
Which CODECs support FAX?
G.711, the most universally installed CODEC, supports FAX because
it has no compression of the signal. A newer T.38 CODEC was designed
to transport FAX by coding the picture signal for transmission
as an image file, not digitizing the analog FAX machine signal.
T./38 is not as commonly available as G.711.
