g729 Codec

G.729 reduces the network bandwidth used by each VoIP call, without sacrificing call quality. Audio compressed with G.729 uses only 1/8 the bandwidth of standard G.711 audio, which allows for more calls to be carried without increasing network capacity and allows voice to travel on limited-bandwidth connections that would otherwise not support VoIP. 

Digium's G.729 Codec for Asterisk is licensed on a per-channel basis. A channel is defined as a single connection from an endpoint to an Asterisk application, or a bi-directional call between two endpoints attached to Asterisk.
