• 🔇 Turn off traffic saving: In the Wi-Fi settings (Settings → Wi-Fi → Advanced) deactivate the "Data saver" option.
• 📵 Use headphones with a microphone: This will reduce echo and improve the voice perception by the other person.

For advanced users: If you are familiar with your router settings, you can prioritize VoWiFi traffic using QoS (Quality of Service)To do this:

1. Go to your router's control panel (usually at 192.168.1.1).
2. Find the section QoS or Traffic priority.
3. Add a port rule 5060–5061 UDP And 5004–5005 UDP (used for VoIP).
4. Set the highest priority for these ports.
