Tips for the best VoIP experience
Call quality depends on your network. Here’s how to get the most out of your connection.
Use Ethernet
A wired CAT5e or CAT6 connection eliminates Wi-Fi interference and delivers consistent low-latency performance.
Enable QoS
Quality of Service prioritizes voice traffic over streaming and downloads, preventing call drops during peak usage.
Dedicated VLAN
Separating voice traffic onto its own VLAN keeps it isolated from general data traffic for maximum reliability.
Check Jitter
Low jitter (under 30ms) matters more than raw speed. Consistent latency keeps calls crystal clear.
