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 is latency dealt with
in VoIP?
Latency means the time delay between transmission and reception
of a signal. Network traffic variations often result in latency
variations from packet to packet known as jitter. Jitter buffers
on the receiving end smooth out the variations to deliver a cleaner
voice signal.
