Comfort Noise
You can prioritize those CODECs which are not CNG (Comfortable Noise Generation”) capable over
those are capable of CNG. If you disable “CNG”, then IP Phone will first try those not-CNG capable
CODECs (such as G.729A and G.723.1 instead of G.729AB and G.723.1A) during call setup. Note, this
is only a best-effort attempt: whenever IP Phone received a silence packet from the peer (SID packets if
G.723.1A is adopted), it will automatically switch to the corresponding CNG-capable CODEC, even you
have disabled “CNG”.
