1 Description

voip gateway is a complete product developed based on Yihang isx series switches. This gateway is a node device between PSTN and ims/ngn, which realizes the interconnection of two communication domains; Based on isx series switches, the device can be easily configured into systems of different sizes, such as 4e1/8e1/16e1/32e1/64e1. Yihang's VoIP customs equipment has two main components: isx switch and server software; The server software is independently developed by Yihang and can be customized into related applications with various special needs

2. Apply

voip Access Transformation: insert it between the customer's PSTN based business system and the operator, convert the operator's IP access to PSTN, and keep the deployment mode and business mode of the customer's business system unchanged

access to soft switch service system: many value-added service integrators have converted the service platform from binding hardware to soft switch based as the center, and only when it is necessary to access the relay or analog phone, they use the switch as the access

traffic operation and transfer system: with the powerful routing and billing functions of Yihang VoIP, it can complete the functions of traffic collection, wholesale, transfer and landing independently or in cooperation with soft switch
