Why Is My Call Quality Poor in Calilio?

Poor call quality in Calilio is usually caused by one of three things: an unstable internet connection, the microphone or speaker in use, or a device under heavy load. Check them in that order. If the call disconnects completely instead of sounding poor, that is a different problem.

How do you check your internet connection?

• Restart your router, then place a test call on a wired internet connection or a different network.
• Choppy or robotic audio usually means data packets are arriving late or out of order, which points to your internet connection rather than a Calilio setting.
• Move closer to your Wi-Fi access point, or switch to mobile data to see whether the problem still persists.
• Close downloads, backups, and video calls that share the same internet connection.

What causes one-way audio on a Calilio call?

One-way audio is usually caused by microphone permissions, mute settings, or audio device configuration rather than your internet connection. Determine who cannot hear whom before you troubleshoot further.

• If the other party cannot hear you, your browser or device may not have permission to access your microphone. Check that microphone access is allowed, and confirm your microphone isn't muted.
• If you cannot hear the other party, check your output device and system volume, and confirm the call is not on hold.
• Bluetooth headsets may occasionally switch audio input or output to the wrong device. Select your headset again in your browser or device settings.

A missing microphone permission is the most common cause of one-way audio, and the steps for checking it differ by browser and device.

What causes echo on a Calilio call?

• Echo is usually caused by a speaker feeding sound back into a microphone in the same room.
• Turn off the speakerphone, lower your speaker volume, or use a headset.
• Keep your microphone away from your speakers, and avoid making calls in rooms with excessive echo.

What device problems cause static or crackling audio?

• Static or crackling is usually caused by a damaged cable, a dirty microphone, or interference from nearby electronics.
• Close the applications you are not using, then restart your browser or the Calilio mobile app to reset the audio device.
• Place the same call from a second device. If the second device sounds clear, the first device is likely the cause.

How do you tell whether the problem affects one business number or one team member?

Determining whether the issue affects a specific business number or team member helps narrow down the cause.

If you have more than one business number, place a test call from a second number, and ask another team member to place the same call. If only one business number or one team member is affected, the cause is likely that number, device, or browser rather than your internet connection. If poor audio occurs on every call, the issue is likely with your internet connection or device.

Is poor call quality caused by your internet connection or your device?

Your internet connection is the first thing to check, and your device is the second. If the audio clears on a wired connection or a different network, your internet connection was likely the cause. If the audio does not clear, change the device by trying another headset or a different browser.
