Steps to reproduce

1. Make a call
2. Leave the call
3. Enter the call again (From IOS to Android)

Expected behaviour

Echo cancellation - I shouldn’t hear myself.

Actual behaviour

I can hear my own echo.

Talk app

Talk app version: latest

Custom Signaling server configured: no

Custom TURN server configured: yes

Custom STUN server configured: yes

in some occasions the noise cancellation doesn’t work and I can hear my own echo. When joining a call from IOS (initiated with Android) it first works as expected. After leaving the call and rejoining (from IOS side) I can constantly hear my echo.
when the Android user disconnects and rejoins the Echo is gone again. So either the issue might be in Android app when someone joins a call or in IOS App when joining an existing call (after previously disconnected).

Someone already reported a similar issue here: #6887

It might be a timing or configuration problem on either IOS or Android when someone joins a call?

EDIT: Another issue could be that IOS or Android or Web is echoing it‘s own input in the own video display. Rocket. Chat had similar problems?
