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.
- 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.
- For CTI-compatible phones, see Compatible Yealink IP Phones, Compatible Fanvil IP Phones, and Compatible Snom IP phones.
- Video call is not supported under CTI mode.
