Abstract:
The purpose of this document is to summarize the development process of a PC -Based telephone exchange \\'ith the capability of recording ,·oice messages and dithering the messages \'Ia mail. Funhermore. the project also im·oh·es multithreaded application development 0\·er dedicated telephony hard,,·are us1nu specialized programming e1wironments and APls. The development of electronics industry has extreme!;; encouraged the com·ers1on of com·entionalltm systems to\\·ards more powerful and sophisticated personal co muter based systems. The major ad,·amage being the degree of comrol that one has on a PC Although, from the past fee\\' decades, the telephone industry has also gone through these changes, but a full PC based solution has never been very successful because of the ,·vulnerability of PC to\\'ards hea,·y processing. The project under discussion suggests the de,·elopement of a hybrid system that ,,.oils in the collaboration of conational telephone exchanges and a personal computer. The project is considered to be most producti,·e and po,,·earful under office e1wironments that are running com·entionalltm·-tcch digital telephone exchanges
