🛠️ Troubleshooting
❓ Why is my call quality poor?
Poor call quality is usually caused by internet connectivity issues. Check your internet speed (minimum 1 Mbps required) and try switching to a different network.
❓ I can't receive incoming calls
Ensure your DID number subscription is active and your app is properly configured. Check that push notifications are enabled on your device.
❓ My calls keep dropping
Call drops are typically caused by network instability. Try connecting to a more stable WiFi network or use cellular data as backup.
❓ The app won't connect
Check your internet connection and firewall settings. Ensure ports 5060-5070 (UDP) are open. Contact support if issues persist.
❓ I hear echo during calls
Echo is usually caused by feedback from speakers. Use headphones or reduce speaker volume. Ensure you're not in a room with hard surfaces that reflect sound.
❓ Calls won't connect
Verify your account has sufficient credit balance and your DID subscription is active. Check that you're dialing with the correct format (10 digits for US numbers).
