Hey Retell team, we are seeing consistently muffled, low clarity audio on the human caller side in Retell call recordings. The agent voice is crystal clear, but the caller audio sounds like it is coming through a tube. This happens across multiple test calls and different testers.
Context:
- Caller used a new iPhone with good mic and solid connection
- Issue reproduces across different calls
- Real-time Transcription denoising is set to Remove noise + background speech
Is this a known issue, and are there recommended settings to improve caller audio quality in recordings?
