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.
If you don't have a deskphone in the office, you can set Linkus Desktop 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 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.
You can control IP phones
, analog phones,
and
Linkus Web Client via Linkus Desktop Client CTI. Supported
operations to manage calls via CTI vary
from
the connected endpoint. Refer to the following table for
details.
