How to Reduce Echo on Business VoIP Calls

Echo on a business call can come from sound picked up by a microphone and returned through a speaker, a headset's sidetone setting, excessive gain, or network delay. The person hearing the echo may not be the person whose device creates it, so ask both sides for details.

Isolate the source

Record the device, location, call direction, and whether the issue occurs on speakerphone, handset, or headset. Compare an internal call with an external call. Check device firmware, microphone placement, headset sidetone, and network latency.

• Test one endpoint at a time with a known-good headset.
• Lower speaker and microphone gain gradually.
• Check whether Bluetooth or a second audio device is active.
• Use provider call-quality reports when network conditions may contribute.
