  Double voice and strong Echo from the other side but not from the agent. I speak my buddy hears me normally but I hear him with a massive echo. This happened most recently on 2 calls out of 30 calls.

To Reproduce

1. Make a call
2. listen to your buddy
3. "enjoy" the echo
4. listen to him reporting that "everything is fine on his end"

Expected behavior No echo from either side.

I don't think this can be attributed to an app issue. Unless it can be reproduced consistently. Seems like a microphone feedback problem or possibly something with the VoIP codec which the provider is responsible for.
