Yeastar Linkus for Google Chrome Extension

Yeastar Linkus for Google Chrome Extension is now fresh out of the oven in the Chrome Web Store, enabling you to miss no call, simplify call handling, and increase call efficiency. With this extension installed, you will save a lot of time on switching among web pages back and forth and avoid distractions.

Click-to-call: Interactive Dialing

This extension turns phone numbers on web pages into clickable links so that you can click to initiate an audio or video call directly when browsing the web, including your CRM system and mailbox. In addition, by enabling the CTI mode, you can directly click to dial through your desktop phone.

Call Pop-ups: Instant Notification & Action

You will be notified of incoming calls with pop-ups showing matched extensions and contacts, where you can take it or hang it up straight away, even when the browser is minimized or closed. It also allows for more call operations, such as transferring the call, putting it on hold, muting it, recording it, etc.

Your Communications Hub: More Operations

This extension also enables you to access the key Linkus features without leaving the web page you are currently on and switching to Linkus Web Client.

  • Use the toolbar dial pad to dial or quickly search for extensions and contacts.
  • Change your presence status and view your colleagues’ status directly in the browser.
  • Receive instant notifications of missed calls and new voicemails.
  • Queue agent can directly pause/unpause, log in/log out.

Note: P-Series users can utilize this Chrome extension alongside Linkus Web Client or Linkus Desktop Client. Please note that all of the above features are supported when this extension is used with Linkus Web Client while only click-to-call, phone number auto-detection on web pages, and website blocklist are supported when used with Linkus Desktop Client.

Just go to the Chrome Web Store, add “Yeastar Linkus for Google” to your Chrome browser, then simply follow the instructions.
