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.
How Does VAD Work?
VAD, or Voice Activity Detection, is a technique that reduces
bandwidth in VoIP telephone systems by listening for the silence
in normal conversations and not transmitting any packets during
these periods.
