Design And Implementation Of Embedded USB Telephone Voice Management Systems

Abstract:In today’s era of public telephone networks Public Switched Telephone Network (PSTN) in a safe, reliable, Internet telephony Voice over Internet Protocol (VOIP) to low-cost, portable, versatile wide range of applications. Existing traditional public telephone network (PSTN) and emerging Internet telephony (VOIP) has been studied and found to have limitations. In order to blend the advantages of using the method of embedded software and hardware technology and network technology combined with coordinated design ideas, developed the embedded USB telephone voice management systems, to achieve a voice call platform management, VOIP platforms and instant messaging platform organic integration.The circuit voice management system through the USB interface connected to a PC, there are two functions which hardware:hardware and paint, can be exchanged between the control outside the three, the equivalent of two outside (outside the ordinary VOIP) an extension phone switch; the hook STATUS inside and outside of the detection and control, testing outside of the ring and counter electrode signal and the inside of the control outside the off-hook and ringing inside and reverse polarity signal to voice interactive Interactive Voice Response (IVR) server automatic voice call processing functions.The telephone voice management system is applicable to enterprises hotline management; a branch or agency of the unified management of telephone calls, unified recording upload, the same pop-up customer information, and collaborative management of the customer data, zero calls internal communication; with existing call center so that the branch and call center customer service operator customer collaboration; VOIP phone gateway, cost-effective, with good promotional value.The basic realization of system functions, but also further optimization of space, such as video function, the phone APP application, to be further improved and perfected. Practice has proved that the system is safe, reliable, low cost, it is an intelligent communication terminal. The overall structure and working principle of each part of the system has been described in detail.
