Codec audio

Codecs are the components through which the voice is compressed and routed to the recipient. Each call must use a codec to make sure that your voice is understandable.

In the table you can see the supported codecs Vohippo and understand the relationship between compression, bandwidth utilization and voice quality.

Codec Load Quality
G.711 uLaw 64 kbit/sec. Excellent
G.711 aLaw 64 kbit/sec. Excellent
GSM 13 kbit/sec. Good
G.729 9 kbit/sec. Good

To have a right value of quality we suggest to use GSM codec or G729. The last codec can be required a license to work.
