基于下一代网络的VoIP语音网关设计与实现

Design and Implementation of VoIP Gateway Based on Next Generation Network

采用网络处理器+DSP作为语音网关解决方案,基于下一代网络VoIP语音网关让语音、数据、视频在IP网络上传送,可以有效地降低企业生产成本.通过对该网关设备的电路设计和音频驱动的开发,选择小巧快速的SIP协议栈为开发对象,实现了通话呼叫功能并通过测试.

The paper introduces the voice, data and video transmission over IP networks by the VoIP voice gateway based on next generation network, which can effectively reduce the cost of production. With the network processor and DSP as VoIP voice gateway solution, we designed the gateway device circuit and developed audio driver. With small and fast Session Initiation Protocol stack for development, a call between two IP phone s is made, meeting the requirements of the test.
