AT Software / Telecommunications
Project Title:
CTI PBX Call Center

Client’s Name (Country):

Lanit Systems (a member of Lanit Holding)


The Challenge:

The client had developed a Computer Telephony Integration solution based on a Windows NT operating system and Dialogic hardware, but the attempt to use standard Windows NT mechanisms for switching control failed. Using 20-years of experience in real-time systems development, AT Software successfully created a CTI system for the client.


The Solution:

On a Windows NT platform, the experts at AT Software designed CTI PBX software that organized the switching process for the server, as well as Call Center application software that implements primary and additional telephone services, such as voice mail. The newly organized switching allows events from the Dialogic hardware drivers to be efficiently dispatched, in addition to launching and controlling the implementation of the server's corresponding functional software components. These support the asynchronous mode of executing standard (library) functions in the application layer from the Dialogic software for Windows NT. They also provide an information-logical interface with the Dialogic hardware drivers. The implemented system components have realized the required quality indices for real-time functioning for the server of a given configuration.


The developed application software provides basic and additional telephone services through analog and digital connection lines. A plan is currently being considered for further development of the server software. Based on the growing subscriber interest (especially from corporate network owners) in computer telephony servers, this plan is aimed at widening the market for such systems.


Tools and Technologies:

C++, Low-level Windows NT programming, Dialogic software


Project Duration (months):
