Linkus Web Client CTI Overview

Linkus Web Client can be used in either softphone mode or CTI mode. This topic describes what is softphone mode and CTI mode, what call operations you can do in each mode, and compatible IP phones.

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

CTI mode

Computer Telephony Integration (CTI) connects a computer with a telephone system, which allows you to control a phone from your computer.

If you prefer a deskphone 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 phone.

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