Research And Implementation Of Cluster Voice Scheduling System Based On IP Telephone

Cluter of audio system as a special means of emergency communication,plays an important role in their professional fields.But traditional dedicated cluster equipment technical development is difficult and expensive.But with the rapid development of IP phone,cluter voice dispatching system based on IP phone received extensive attention.In this paper,according to the requirements of the telephone dispatching system function expansion,the key agreement of IP telephone voice dispatching system,on the basis of in-depth study,we design a based on SIP protocol implementation of IP telephone dispatching system of scheduling function.This paper first introduces the IP telephony voice dispatching cluter system involves all the key technology mainly involved in signaling technology,audio,data processing,real-time transport protocol and load balance technology of four aspects.The scheduling system in special scheduling functions are realized through the improvement of overall architecture.On sudio processing in the system is in order to ensure the quality of voice session scheduling system voice.Voice diapatching control system based on IP phone cluter key technologies of detailed research,provides a good system design and implementation of the premise.Secondly design the overall architecture of the system,and the analysis is given on the system of voice dispatching load balancer based on SIP session,cluter server and the overall design scheme of each terminal,focusing on the SIP server,design of SIP message and the network module,the specific working process of terminal is given,and the specified calling business.On this basis,the main function of voice dispatching system implements the cluter,including basic functions,the dispatcher station scheduling function,strong pull and demolitions and so on.In the lab at the end of the paper for the implemention of the experiment device based on embedded peogramming this cluter voice dispatching system experiment,functional and backgroud data analysis shows that the system works well and has reached the design target.
