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.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.

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

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