基于SIP协议的临床呼叫语音网关的设计
Design of clinical call voice gateway based on SIP protocol
摘要
Abstract
Based on the ARM9 CPU Mini2440 and using the SIP protocol,a small voice gateway which is controlled the clinical call signaling was presented. The analog signal was processed with sampling,digitization ,compression coding,packaging and grouping,distribution route,storage and exchange,unzip etc,the voice communication was realized in the IP network. The conversion from complex protocol to SIP standard protocol was realized in the gateway, the signal can be transmitted in the whole building. The test results showed that the communication voice quality is good and there is no speech delay.关键词
