Research And Design Of Enterprise's VoIP Based On Softswitch

Softswitch technology is developed step by step based on the IP telephony, which is the core technology of the Next-Generation Network (NGN) that can handles voice, fax, data, and routes calls across different types of networks. Combining Softswitch technology with Intranet IP telephony not only can integrate dissimilar networks and network components, but support interconnection with current VoIP technology in Intranet. What is more, deploying VoIP in Intranet based on Softswitch makes supplying newer services more easy regardless of the network components.In this paper, we first analyze softeswitch technology and IP telephony technology, and bring forward using the MGCP to construct the enterprice's VoIP network, and show the whole design scheme of control model. In the design we adopt the layered model and client/server model which make the soft transplantable and expansible well. Finally in this paper we detailedly depict the realization of the call control model based on the MGCP protocol.
