MGCP protocol is introduced which is adopted by VoIP system communication with the core of Softswitch technology. After analyse the process of calling based MGCP protocol, we design a system model of VoIP in business. NAT/firewall penetration technology , user certification of security and the design of the Integrated Access Gateway are researched relatively in article.
