Control a Yealink IP Phone by Linkus Web Client

This topic describes how to connect a compatible Yealink IP phone to Linkus Web Client, and what operations you can do to manage phone calls on the connected phone from Linkus Web Client.

Applications

This topic is applied to the Yealink IP phones that are compatible with Linkus Web Client CTI.

For compatible IP phones, see Compatible Yealink IP Phones.

Tip: For incompatible IP phones, refer to Control an Incompatible IP phone by Linkus Web Client for instructions on phone control.

Background information

By enabling CTI mode on Linkus Web Client, a Yealink IP phone with your extension registered can be connected to your Linkus Web Client. In this way, Linkus Web Client acts as a visual control panel whereas calls are made and received from the Yealink IP phone.

Procedure

To connect a compatible Yealink IP phone to Linkus Web Client, you need to do as follows:

Step1. Set up PBX to allow control over Yealink IP phones

Contact system administrator to check if your organization's PBX server is ready.

  1. Check if the version of PBX server is 37.3.0.16 or later.
  2. Check if uaCSTA feature is enabled (PBX Settings > SIP Settings > Advanced > Other Options > Enable uaCSTA connection).
    Note: uaCSTA feature allows you to use Linkus Web Client to connect to and manage a compatible Yealink IP phone.

Step2. Set IP phones to be controllable

Check if your IP phone is ready for being controlled.

  1. Check if the extension registered on the IP phone is the same as that of Linkus Web Client.
    Note: Register only one account on the IP phone, or CTI feature may not work.
  2. If system administrator has assigned your extension to the IP phone via Auto Provisioning, your IP phone is ready for being controlled.
    Note: CSTA Control feature is enabled in the default Auto Provisioning template that is provided by PBX for your IP phone.
  3. If system administrator has manually registered your extension to the IP phone, you need to enable CSTA control feature on the IP phone.

    The following instructions take Yealink T56A as an example.

    1. Log in to the phone web interface.
    2. Go to Features > Remote Control.
    3. On the Remote Control page, turn on the option CSTA Control.

    4. Click Confirm.
    5. In the pop-up dialog box, click OK to reboot the phone.

Step3. Enable CTI mode on Linkus Web Client

Change Linkus Web Client to CTI mode, so that you can use Linkus Web Client to manage phone calls on your IP phone.

  1. Log in to Linkus Web Client.
  2. At the top toolbar, select the connected Yealink IP phone from the drop-down list.
