Description: FXS VoIP Gateway
CoreIP 128S/H FXS VoIP Gateway is a cutting-edge solution that combines VOIP and TDM networks for service providers and application developers. It has a modular design with a built-in server and opens a new milestone to maximize VOIP and TDM network’s value. Tailored to satisfy diverse customers’ needs, CoreIP UMGW enables users to develop a range of applications with its open and standardized format. Moreover, the Hybrid architecture of CoreIP Media Gateway allows for standard protocols between different network components and ensures high flexibility and compatibility for complex communications. Additionally, in the Mobile Internet Era, it brings about efficiency and unparalleled cost advantages for developers by streamlining R&D and integrating various data, voice, and video applications.
Some of the key features of CoreIP 128S/H FXS VoIP Gateway are:
Flexible configuration for any network – It works with diverse networks (FXO, FXS) and provides various multimedia processing capabilities (conferencing, fax, compression, and echo cancellation) and protocols for voice enhancement.
Compatibility with any IP-based applications – It has an optional inbuilt industrial server that makes it compatible with any IP-based applications. It also supports different types of third-party software, such as UC, IP-PBX, Contact Center, and more. In addition, it can also converge applications in legacy PSTN networks via internal modules.
Multimedia convergence – It uses a 100M-Ethernet switching chipset to exchange media streams in IP packets and connects to the soft switching system via the Media Gateway Controller, ensuring smooth and high-quality applications.
Diverse media resources – It supports high-capacity voice playback and codecs, conferencing, and faxing. It supports T.38/T.30 and is optimized for IP-PBX, IVR, and ACD applications. It also has an EXT IVR server or GUI management for easy operation.
Carrier-grade reliability – It has a special power system with standby redundancy, an advanced cooling system, and a special air cleaner to ensure durability and stability. It also has an inside temperature control and alert system and a convenient wiring system that does ot require changes when switching functional modules.
