[Asterisk-Users] Aggressive Suppression and Comfort Noise
We can all agree that the Aggressive Suppression code has gone a long way to solving the echo problems of Asterisk. I, and others, have noticed that its methods do seem a little harsh at time because it seems all sound cuts out during suppression. Would it be possible to add comfort noise to suppression periods so instead of all sound cutting out during suppression, you would at least hear what sounds like normal line noise. I think this would greatly round out the overall sound and make the suppression sound softer and less harsh.

[Asterisk-Users] Aggressive Suppression and Comfort Noise
Voip channel detection by the zap channel would be more helpful. The Aggressive Suppressor would only operate when a channel is patched to voip. All other times it could either be set to lower suppression thresholds or revert to one of the other (or no) echo_cans. I would suspect that adding noise is low on the echo_can priority list until the basic functionality becomes more ideal.
