This article outlines recommended steps to troubleshoot call quality issues experienced in the web version, mobile apps, or desktop apps.
Network and internet connection
Because DialLink, like all VoIP systems, relies on a stable internet connection, most call quality issues are related to network performance.
Recommended steps
Restart your router: Power off your Wi-Fi router for at least 30 seconds, then turn it back on.
Switch networks: Try cellular data instead of Wi-Fi, or switch to a different Wi-Fi network.
Use an Ethernet connection instead of Wi-Fi: Wired connections are more stable and help reduce jitter and latency.
Reduce network load: Close bandwidth-intensive apps (video streaming, large downloads, cloud sync).
Test network speed: Use a tool like Speedtest by Ookla to check your connection speed and stability.
Improve router placement: Ensure strong Wi-Fi signal strength and avoid physical obstructions.
Turn off VPNs or firewalls that inspect VoIP traffic: These can introduce latency or packet loss
Device and hardware performance
Devices that you use can also affect audio quality.
Recommended steps
Close background apps: Stop CPU- or memory-intensive programs during calls.
Restart your device: Fully power off and restart to clear temporary system issues.
Update software: Ensure the DialLink app and your operating system are up to date.
Switch devices: Test the call on another device (mobile vs desktop) to identify device-specific problems.
Audio settings
Incorrect audio setup can lead to echo, distortion, or audio loss.
Recommended steps
Verify input and output devices: Confirm the correct microphone and speaker are selected.
Adjust microphone positioning: Keep the microphone unobstructed and at an appropriate distance.
Avoid blocking speakers: Ensure speakers are not covered or too close to the microphone.
Lower speaker volume: Reduce volume to prevent echo or feedback loops.
Use a headset: A wired or Bluetooth headset improves audio clarity and reduces background noise.
Disconnect unused audio devices: Remove unused Bluetooth or USB audio devices that may interfere.
