The G.729 codec compresses the payload at 8 kbit / s, which gives it up to eight (8) times the capacity on the same connection. Ideal for use in scenarios of limited bandwidth, such as ADSL connections, international VoIP service, satellite connections, among others.
When using G.729 compression and the Digium IAX2 signaling protocol, on a T1 / E1 link, you can expect around 140 simultaneous calls through the same link.
Without the G.729 Codec, the advanced features of the Asterisk exchange, such as call conferencing, DTMF digits collection, call recording and more, will not work.
- Compatible with the Digium technical support organization for use in x86 and x86_64 Linux environments.
- The license is granted per channel.
- You can use the G.729 codec with Asterisk and any combination of phone cards.
- Uses the CPU power of the host system to perform media transformations.
- The implementation allows the Asterisk software to convert audio between G.729 and any other compatible codec.
- Multiple versions of G.729 are defined according to industry standards. The asterisk and the implementation of Digium G.729 are compatible with Annex A G.729 (a.k.a. G.729a).
- Calls can be exchanged with Asterisk directly at a fraction of the bandwidth of the G.711 standard.
- Some IP telephones and VoIP gateways include support for G.729.
