Several different speech codecs can be used for stream audio compression. Commonly used codecs for [VOIP] traffic contain G.711, G.723.1 and G.729, all ITU-T-specified.

What is [VOIP] Telephony System Management?: Many of the largest carriërs employ H.323 in their core backbones, and the vast majority of callers have small or no belief that their POTS calls are being terminated over VoIP.
