I have been using PhonerLite and would like to improve the overall call quality, especially during longer calls. Sometimes the audio does not feel as clear or stable as expected, and I am trying to understand whether the issue could be related to the settings, headset, or VoIP provider.

What settings or troubleshooting steps have worked well for other PhonerLite users? I would especially appreciate suggestions for getting clearer audio and reducing occasional noise or interruptions.
