Description: Types of voice codecs on the current call.
G.711, G.726, G.729 and G.723 are ITU-T standards for voice and multimedia modulation and digital encoding.
Valid values for this variable can be:
* g711Ulaw - G.711 Ulaw coding standard at 64 kbps * g711Alaw - G.711 Alaw coding standard at 64 kbps * g726 - G.726 ADPCM coding stardards at 48/56/64 kbps * g729A - G.729 Annex A CS-ACELP coding standard at 8 kbps * g729B - G.729 Annex B CS-ACELP coding standard with silence suppressionat 8 kbps * g729E - G.729 Annex E CS-ACELP coding standard with silence suppressionat 11.8 kbps * g723R1KBPS5Dot3 - G.723.1 coding standard at 5.3 kbps * g723R1KBPS6Dot3 - G.723.1 coding standard at 6.3 kbps * g723R1AKBPS5Dot3 - G.723.1 Annex A coding standard at 5.3 kbps * g723R1AKBPS6Dot3 - G.723.1 Annex coding standard at 6.3 kbps
What is channelActiveCodec?
The voice codec currently in use on this call, one of the ITU-T G.711/G.726/G.729/G.723.1 variants (e.g. g711Ulaw at 64kbps or g729A at 8kbps). Comparing this against expected bandwidth budgets helps explain unexpectedly high or low per-call bandwidth usage.
