CTI Server.
The CTI Server, CTI Clients, and Unified ICM
Unified ICM is central to Cisco’s overall call center routing solution. The Cisco CTI Server is the heart 
of Cisco’s CTI. This section gives an overview of how they fit together.
The CTI Server provides an interface between Intelligent Contact Management software and client CTI 
applications so that these applications can make use of the enterprise wide routing data managed by 
Unified ICM. The CTI Server runs at the call center site on an Unified ICM Peripheral Gateway (PG) 
with ACD interface software.

at one or several call centers in the enterprise.

CTI Server Overview
The two most common CTI-enabled applications are screen-pop integrations and third-party control 
applications. 
In a screen-pop integration, the CTI Server sends call flow events to the application (either on a 
dedicated application server or on an agent’s desktop); the application interprets these call flow events 
to retrieve call context data. This call context data is used to either pre-populate the screens on an agent’s 
workflow application (for example, a CRM application) or to record work events (for example, calls and 
agent states) into a workforce management system. 
In a third-party control application, the CTI Server accepts commands that are in turn passed on through 
the PG and to the ACD to which it is connected. For example, a common third-party control application 
is a softphone, which enables the agent to control their telephone set via their computer. This is 
especially useful when the softphone application can be integrated with the agent’s workflow 
application, and can take advantage of integration features such as call wrap-up data, call context (data) 
transfer on consultation calls, and application-driven speed-dial lists.
