Computer Telephony Integration (CTI) is the linking of telecommunications with electronic data processing.
In practice, the systems are often used in e-mail programs, (for example, Microsoft Outlook) integrated and feature a TAPI-interface. Among other things, stored contacts may be called directly from the e-mail program. Furthermore, CTI modules come with or without fax capability.
The CTI allows computer programs out of the default configuration, acceptance and termination of telephone calls, the structure of the conference calls, sending and receiving faxes, directory services, and the further transfer of calls.
Through automatic caller identification, the matching record from a database can be brought to a screen with customer data. Furthermore, it is also possible to run a journal of the calls made. This technology is primarily used by call centers.
