Design and implement of the VoIP amplifying telephone communication system based on simplified MGCP
on the basis of the analysis about the existing large-scale industrial and mining enterprises amplifying telephone communication system, a VoIP amplifying telephone communication system based on simplified MGCP is proposed and realized. DSP, CPLD and network interface circuit are adopted to design the terminal, MGC and TMG of the system. Based on analysis of the MGCP protocol, a DSP-based simplified MGCP stack is implemented. The simplified MGCP task is created with μC/OS-Ⅱ embedded operating system, which shows the advantages of simple structure, easy debugging, good stability and low cost in practice. The experimental results reveal that the spicing control and Voice transmission of the system works stably and reliably, and the application of the system improves production efficiency, production management level and network utilization.
