Acoustic echo cancellation

[francescocarzaniga]

Hi all,

I am trying to use JsSIP in a simple two-way call environment with a SIP softphone. The JsSIP client (Android WebView) has quite a terrible echo problem, and I cannot seem to get rid of it. As I understand, WebRTC is supposed to do echo cancellation on its own, but it's not working at all. I tried setting mediaConstraints to echoCancellation: true and other tricks, but no luck.

Side note, I think I had seen something to this effect on the mailing list, but now it's completely inaccessible to me. Is there any way to get all those topics back?
