Messaging Conventions
Communication between the CTI client and the CTI Server is accomplished by the exchange of
messages. Cisco’s CTI Server message set is modeled after the Computer-Supported
Telecommunications Applications (CSTA) messaging conventions defined by the European Computer
Manufacturers Association. CTI Server messages, in general, follow CSTA naming conventions and the
request/confirmation and unsolicited event paradigms. However, CTI Server messages use a simpler set
of data types than those defined by CSTA.

In the CSTA model, one party acts as a server and the other as a client. In the Cisco interface, as the
names suggest, the CTI client takes the client role and issues requests to the Unified CCE. The Unified
CCE CTI Server takes the server role, responding to requests from the CTI clients and originating
unsolicited events.
