Codec Preference

Codec is known as Coder-Decoder used for data signal conversion. Set the priority of voice compression; Priority 1 owns the top priority.

•G.729: It is used to encoder and decoder voice information into a single packet which reduces the bandwidth consumption. 8kbps bandwidth is needed.

•G.711μ-LAW:It is a basic non-compressed encoder and decoder technique. μ-LAW uses pulse code modulation (PCM) encoder and decoder to convert 14-bit linear sample. 64kbps bandwidth is needed.

•G.711A-LAW:It is a basic non-compressed encoder and decoder technique. μ-LAW uses pulse code modulation (PCM) encoder and decoder to convert 13-bit linear sample. 64kbps bandwidth is needed.

•Non-used:Only available in Priority 2 and 3. It is selected if codec is not to be used.

Codec priority is assigned in the order as G.729 > G.711μ-LAW > G.711A-
