TOPIC: Free G729 Codec installation in Asterisk

    In this article you will learn how to install Free G729 codec in Asterisk based dialers and PBX like vicidial, Goautodial, Freepbx, Elastix, Issabel, Vitalpbx. The Free g729 codec is available from the asterisk.hosting.lv website.

    Apart from Free G729 codec, I do recommend to use the official G729 codec provided by digium or sangoma either software version or hardware g729 cards.

What is CODEC ?

    A Codec is a technical term for the following variations, which essentially mean the same thing: compression – decompression / compressor – decompressor / Code Decode.
A codec is a hardware- or software-based process that compresses and decompresses large amounts of data's like audio files in VOIP.

G729 vs G711

    G.729 and G.711 are two different codecs used by mainstream voice-over-internet-protocol (VoIP) systems that transmit phone calls as data over the internet. G.711 offers better audio quality,but requires more bandwidth. G.729, on the other hand, requires less bandwidth, but call quality can suffer
Follow the below steps to install the proper G729 codec for asterisks

Bandwidth of G.729 vs G.711?

    On average, a call made over G.729 consumed about 8 Kbps of bandwidth per call because it compresses the data being transmitted over the internet. In comparison, G.711 uses 64 Kbps for its uncompressed call data.

Why we need G729 in asterisk

1.Less bandwidth consumption.
2.If VOIP provider only support G729 codec.
3.User dialing via low speed internet.
