Linkus Web Client CTI Overview

Linkus Web Client can be used in softphone mode or CTI mode. This topic describes what is softphone mode and CTI mode and what call operations you can perform in each mode.

Softphone mode

A softphone is a software-based phone that is equivalent to a traditional deskphone, which allows you to make and receive calls over the Internet via a computer. A softphone not only has all the features of a deskphone, but also has additional features typical for online messaging, such as chat, video call, extension presence, etc.

If you don't have a deskphone in the office, you can set Linkus Web Client to softphone mode. In this way, you can perform the following operations to manage phone calls on your computer:
  • Make/End a call
  • Make a second call
  • Answer/Reject a call
  • Mute/Unmute a call
  • Transfer a call (attended transfer and blind transfer)
  • Record a call
  • Hold/Resume a call
  • Swap hold
  • Add participant
  • Merge calls
  • Call flip
  • And more

CTI mode

Computer Telephony Integration (CTI) connects a computer with a telephone system, which allows you to manage phone calls right on a computer.

If you prefer a deskphone or Linkus Desktop Client for communication, you can set Linkus Web Client to CTI mode. In this way, Linkus Web Client acts as a visual control panel on which you can perform the supported call operations, whereas calls are made and received from the connected deskphone / Linkus Desktop Client.

You can control IP phones , analog phones, and Linkus Desktop Client via Linkus Web Client CTI. Supported operations to manage calls via CTI vary from the connected endpoint. Refer to the following table for details.
