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:

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.

Using USB call recording

  3. Plantronics CS520 Headset
  4. Yealink EHS36 Adapter
  5. RJ12 Cord

  1. Connect the RJ12 Cord (5) to the Yealink EHS36 Adapter(4).

2. Connect the 3.5mm DC Jack(1) to the Yealink EHS36 Adapter(4). Note that you only need the DC Jack in this end, you do not need to fill this socket.

3. Connect the Plantronics Base(6) to the power supply(7).

4. Connect the Plantronics phone cord(2) to the Plantronics Base(6).

5. Connect the 3.5mm DC Jack(1) to the Plantronics Base(6).

You shouldn’t need to change any of the settings in the phone as the Yealink EHS36 should work out of the box. However, you will want to check that on the bottom of the Plantronics base that the Dial’s are set correctly. This should be the correct setting for the dials :

How to: Connect a Plantronics CS540 with a Yealink Phone

This is a step-by-step guide of how to successfully connect a Plantronics CS540 to a Yealink SIP phone (Compatible with T26P, T28P, T38G).

You should have:
– Plantronics CS540 Headset
– Yealink Handset with EHS capabilities
– Yealink EHS36 adapter.

(For a full list of headset and phone compatibility please view our headset compatibility chart)

The image below shows the contents of each box that will be required for this setup. They have been labelled for ease of idenitification and grouped according to which box you will find them in -see the key below.

Green – Yealink T38G Box
Yellow – Yealink EHS36 Box
Red – Plantronics CS540 Box

Step 1:
Once you have the correct parts ready, the next step is to connect the 3.5mm cable from the Plantronics base unit, to the EHS36 box. You can’t really go wrong here as they will only fit into one slot on each unit, but the picture below highlights where to connect them.

Step 2:
Connect the RJ12 cable from the EHS36 box to the EXT port on the back of the T38G. This port should be clearly labelled on the phone. See the picture below for illustration.

Step 3:
Connect the Plantronics RJ11 cable from the base unit to the Headset port on the back of the T38G. This port is labelled with a small headset icon, it is located next to the Receiver port, please make sure these are put into the correct slots. Again, the picture below shows how they should be connected.

That’s it! Power up the phone and the Plantronics base if you have not done so already. If this is a new purchase please allow a short time for the headset to charge before use. To charge simply place it onto the base in the very obvious slot.

If you have any problems after following this guide, please email with details of your issue and a member of the technical team will be happy to advise.
