Network & Device Tips to Improve Call Quality
Simple adjustments often make the biggest difference for both Telegram and browser calls.
Prefer Wired or 5GHz Wi-Fi
Use Ethernet or a strong 5GHz Wi-Fi connection to reduce jitter and packet loss.
Close Background Apps
Free CPU and network resources by closing large uploads, VPNs, or streaming services during calls.
Use a Headset
Headsets reduce echo and dramatically improve perceived audio quality.
Choose the Right Browser
Use latest Chrome, Edge, or Firefox for best WebRTC performance. Mobile Safari also supports WebRTC but may have limitations on some features.
Test Before Important Calls
Run a short test call to verify microphone, speakers, and network prior to customer or sales calls.
