Common Issues & Solutions
Most issues have simple solutions. This guide covers the most common problems our support team sees and how to fix them without waiting for help.
Everything You Need
Enterprise-grade features without the complexity.
Choppy or Robotic Audio
Usually caused by network issues. Switch to wired Ethernet, enable QoS on your router, or close bandwidth-heavy apps.
One-Way Audio
You can hear them but they can't hear you (or vice versa). Check firewall settings — UDP ports may be blocked.
Calls Going to Voicemail
Check your availability status in the app. Make sure you're set to 'Available,' not 'Away' or 'Do Not Disturb.'
Echo on Calls
Use a headset instead of speakers. If using speakers, reduce the volume and check that echo cancellation is enabled.
App Won't Connect
Check your internet connection. Try switching between WiFi and mobile data. Reinstall the app if the issue persists.
Can't Hear Ringtone
Check app notification permissions on your device. On mobile, ensure VestaCall is allowed to send notifications and play sounds.
