Introduction

Overview

Sometimes echo may occur during a call. In general, this issue is related to the server. For example, some Neox PBX systems may cause echo during calls. When call recording is enabled on the PBX, echo may be heard on the phone. When call recording is disabled on the PBX, the phone usually works normally without echo.

Applicable Models

This applies to all models of our phones.

Target Audience

Solution

Disable the Voice Activity Detection function on the phone. Even if the Neox PBX supports call recording, echo will no longer occur after this setting is turned off.
