Yealink Handset Crackling or Buzzing from Handset and Speakerphone

You may occasionally notice that your Yealink phone starts crackling or buzzing.  This has most commonly been observed after the phone has been in operation for sometime without being rebooted or after a firmware update.

Below are some troubleshooting steps that you can try to resolve the buzzing and crackling

  • Try restarting the Yealink Phone (You can either remove the Power or Ethernet Cable if using PoE, alternatively just hold down the X key until you are prompted to restart the phone)
  • Try a Factory Reset on the Phone, ensure that you have all the required settings to reconfigure the device after the factory reset.
  • Update the phone firmware to the latest release and then perform a factory reset prior to configuring or provisioning the phone again.
  • Confirm if crackling or buzzing is just occurring from the handset or also from the speakerphone.  If just the handset exhibits the issue then the cable or handset may need to be replaced.
  • Ensure that the VoIP/SIP Phone System is up to date
  • Ensure that you are using the most appropriate voice Codecs for your phones and the SIP Trunk. (A-law is commonly used in Europe and u-law is generally used in the United States)

How to install Win32_Product WMI Class on Windows Server 2003 and Windows SBS 2003

The Win32_Product class is not installed by default on Windows Server 2003. If you want to run a WMI script against a Windows 2003 machine you’ll need to do the following:

1.

In Add or Remove Programs, click Add/Remove Windows Components.

2.

In the Windows Components Wizard, select Management and Monitoring Tools and then click Details.

3.

In the Management and Monitoring Tools dialog box, select WMI Windows Installer Provider and then click OK.

4.

Click Next.

Please note that you will require Server 2003 or SBS 2003 – Disk 1 in the drive at the time of adding the component to your server.

This is known to impact the GFI Max Remote Management Asset Tracking feature when running on a Windows Server 2003 or Windows SBS 2003 server.  Software Versions may not be displayed for some products as GFI use a WMI query to the Win32_Product WMI Class which is not installed by default.
