Avalanche: why does the voice sounds distorted from a decoded G729AB stream of a SIPNG test?


The Avalanche's implementation of G729 is G729AB which includes VAD (voice activity detection). When decoding a raw file extracted from the pcap, the stream/voice could be distorted if the decoder cannot convert raw file into pcm format because of the VAD feature. This is a decoder problem and not releated to the G729AB codec.

The Avalanche currently does not support G729A without VAD.
