Linkus Desktop Client CTI Overview
Linkus Desktop 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.
- 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 deskphone or Linkus Web Client for communication, you can set Linkus Desktop Client to CTI mode. In this way, Linkus Desktop Client acts as a visual control panel where you can perform the supported call operations, whereas calls are made and received from the connected deskphone / Linkus Web Client.
- For CTI-compatible phones, see Compatible Yealink IP phones, Compatible Fanvil IP phones, and Compatible Snom IP phones.
- Video call and function key are not supported under CTI mode.
