Audio issues using iOS SDK

Hello,

We’re developing an app using the iOS SDK that uses our own jitsi-meet servers. The app only establishes conferences between two users using p2p communication whenever possible. It usually works fine but in scenarios with a moderate level of background noise and / or when the 2 users speak at the same time we observe a notable decline of voice quality even voice cuts . Our guess is that it might be related to ACG, AEC but don’t really know. Also, we have observed that the use of headsets improves the situation greatly but we cannot use them in our solution. Any suggestions on how to improve this?

Thanks in advance.
