Analysis of VoIP configuration on the Cisco router of Wenzhou Branch

VoIP is a technology that transmits voice over the Internet. It has grown with the development of Internet technology. It integrates voice technology with network transmission, and gives full play to the role of the network. This article takes China Construction Bank of Zhejiang Province as an example to introduce how to use Cisco router to implement VoIP.
The Computer Communication Network of China Construction Bank Zhejiang Branch is a province-wide TCP/IP-based network system. It rents lines of telecom and radio and television companies between provincial branches and municipal branches to achieve wide area network, the network bandwidth between the provincial branch and the municipal branch is 2 MB.
In the construction of China Construction Bank's call center for the province's CallCenter project customer call service center), it adopted the voice relay branch access mode, with the province-wide concentration of agents. In order to enable customers to enjoy the service of provincial center agents by calling the local 95533 China Construction Bank uniform Special Service Code), VoIP technology is adopted between municipal banks and provincial banks.
Solution Design
The provincial branches need to process a large number of voice and fax services, so the Cisco AS 5300 universal access server with a large capacity is used. Each city branch uses Cisco
3640 vro and configure the corresponding voice module. The voice module can insert the corresponding Voice interface card based on the signal type of The Voice port. Cisco routers support three basic voice signal types: FXO external exchange telephone board port), FXS external exchange workstation port), E & M ("receive
And transmit "port, also known as" Ear and Mouth "port ). AS 5300 uses the FXO port to connect to the provincial center Lucent digital switch, Cisco
3640 the FXO port is used to connect to the voice card of the industrial computer.
