Linkus Overview

Yeastar Linkus is designed to keep users connected with colleagues, business partners, and customers anywhere and anytime. To help you quickly understand how to set up and use Yeastar Linkus, we provide an overview on it, including information on Linkus server, Linkus clients, and Linkus event notifications.

Linkus server

You need to configure Linkus server according to the users' needs for using Linkus.
  • If users only need to use Linkus within the company's Local Area Network (LAN), you need to complete the following settings on Linkus Server:
  • If users need to use Linkus outside the company, you should set up Linkus server for remote access. Yeastar P-Series PBX System provides the following two remote working solutions to help you set up a remote Linkus server.
    Remote Access Service (RAS)
    Remote Access Service is a subscription-based service designed for remote working, which is included in Standard Plan, Enterprise Plan, and Ultimate Plan. After you subscribe to the plan to get Remote Access Service, you can bind a Yeastar FQDN to the PBX, and enjoy the following benefits:
    • Secure connection
    • Network Address Translation (NAT) for Linkus service auto configured
    • Linkus server for remote access auto configured
    • Remote access to Linkus Web Client, Desktop Client and Mobile Client
    • Advanced Linkus features, such as Instant Messaging (IM), video call and video conferencing
    If you choose this solution, refer to the following topics to complete the setup.
    Manual configuration
    If you don't subscribe to Remote Access Service and users need to use Linkus in external network, you have to go through complicated server and network settings, such as port forwarding, NAT and public IP address configuration, so as to implement remote access to Linkus.
    Note:
    • Weak network protection will cause SIP attacks.
    • Incorrect configurations may cause one-way audio issue.
    • Linkus server that is manually configured does NOT support remote access to Linkus Web Client, and the features of Instant Messaging (IM), video call and video conferencing.
    If you choose this solution, refer to the following topics to complete the setup.
