  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

  How Much Bandwidth Do I Need for 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 or vicidial based servers.

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

  OPTION 2: Manual Install G729 codec

The Free G729 codec all available in the below link

https://asterisk.hosting.lv/

Before Downloading the codec you need to Know below details

1. 32 bit or 64 bit

2. asterisk version

3. server type like: intel, amd

    Command to Check OS BIT type

uname -a

if output shows i386 then its 32bit

if outout shows x86 then its 64bit

    Command to Check asterisk Version

asterisk -rx "core show version"

    Command to Check server Processor Type

cat /proc/cpuinfo

As of writing this blog article my asterisk verision is 1.8, 64bit
