Symptoms
- Multiple voices overlap and become hard to understand
- Audio cuts out when several people talk at once
- One participant's audio is consistently choppy
- Issue is worse with more people on the call
Likely causes
- CommonMultiple unmuted microphones picking up background noiseGroup calls often have overlapping audio when several mics are open at once in noisy environments.
- CommonOne participant's weak internet or cellular connectionA single poor connection can cause choppy audio that affects the whole call's flow.
- PossibleApp bandwidth limitations with many participantsSome calling apps struggle to maintain quality as participant count grows.
- PossibleDevice performance strain with many video/audio streamsOlder or busy phones can struggle processing many simultaneous audio streams.
- Less commonApp server-side issueAn outage or slowdown at the calling app's servers affects everyone at once.
What to do
- Mute your microphone when not speaking, and ask other participants to do the same.
- Check your own Wi-Fi or cellular signal strength and move closer to your router if needed.
- Close other apps running in the background to free up phone resources.
- Ask if one specific participant's connection seems to be causing the issue and have them rejoin.
- Switch from video to audio-only if the call supports it, to reduce bandwidth strain.
- Update the calling app to the latest version.
- Try a different calling app to see if the issue is specific to one platform.
- If issues persist across apps and networks with the same group, consider splitting into smaller calls.
When to call a pro
If group call quality is consistently poor for everyone across different apps, this may indicate a broader network capacity issue worth discussing with an IT professional for business use.
