Enabling USB call recording

By default this feature is disabled, if you wish to use a USB stick to record calls you need to enable the following parameter:

features.usb_call_recording.enable
Valid Values: 0 or 1
1 = ON
0 = OFF

Note: this feature cannot be enabled via the web user interface or via the phone directly. It can only be done by a provisioning parameter.

If you are having your Yealink devices provisioned by ourselves and would like to use this feature just drop us an email and we can apply this to your template.

Uploading a CFG file

If you aren’t able to provision this setting to the device you can add the settings below to a plain-text file and upload it directly to the unit from a PC and it will enable the feature:

#!version:1.0.0.1
features.usb_call_recording.enable = 1
Remember to save the text file as “.cfg”

To upload the config file login to the web user interface of the phone and go to “Settings” > “Configuration” > Select the “Choose File” button next to “Import CFG Configuration File” and select the file on your PC > After selecting the file press the “Import” button for it to upload.

After the file has been uploaded the setting will be enabled.
