Poor VoIP call quality can transform professional communication from seamless to frustrating. Whether you're a remote worker, business professional or home user, understanding how to diagnose and resolve voice transmission issues is crucial for maintaining effective communication.
Diagnosing Your VoIP Call Quality
VoIP performance depends on multiple interconnected factors. By systematically addressing these key areas, you can significantly improve your call experience.
Internet Connection Fundamentals
Your internet connection forms the backbone of VoIP communication. Critical metrics include:
- Bandwidth: Minimum 100-150 kbps per call
- Latency: Under 150 milliseconds
- Jitter: Below 30 milliseconds
- Packet Loss: Less than 2%
Network Hardware Optimisation
Your network infrastructure significantly impacts call quality. Key recommendations include:
- Upgrade to business-grade routers with Quality of Service (QoS)
- Prioritise VoIP traffic in router settings
- Use wired Ethernet connections over Wi-Fi
- Disable problematic SIP ALG features
Practical Troubleshooting Steps
