CTI architecture

In the coupling between the telecommunications and the DP world, a distinction is made between two CTI architectures: first-party telephony and third-party telephony.

First-party telephony is a physical link at terminal level, whereby the personal computer (PC) and the telephone are directly connected to each other. The personal computer can be connected to the telephone or to the PBX.

The first architecture is referred to as telephone-centric coupling, the second as PC-centric coupling. In this coupling, the telephone receives access to the PBX or the network via the personal computer. The personal computer is used to control the operation of the telephone. In addition, the personal computer can take over data communication tasks. First-party telephony is also known as a stand-alone solution and is supported by the TelephonyApplication Programming Interface (TAPI).

With third-party telephony, the logical connection is at the system level. The personal computers do not control the telephones, but the PBX via a telephony server. In this way, incoming and outgoing calls can be analyzed and assigned to the corresponding personal computers and telephones.
