Voice VAS Platform

The Superior VAS Platform for Voice Applications

The Ehangcom voice VAS platform is based on iSX1000 or iSX4000 Universal Application Platform.  iSX1000 targets small to medium deployment up to 8E1 per system and iSX4000 targets high-density deployment up to 64E1 plus STM-1 per system.  Its modular design offers low entry cost for small deployments, which makes it ideal for proof of concept for new VAS services.  Its field upgradeable flexibility allows operators to expand capacity quickly for popular VAS services to capture market opportunities.  Ehangcom voice VAS platform offers TDM interfaces to connect to legacy TDM networks and offers NGN interfaces to connect to the NGN/IMS networks.

The Ehangcom voice VAS platforms use the best-in-class, dedicated DSP technologies for IVR, conferencing and VoIP codec.  In contrast to host based media processing solution which shares the same pool of resources as OS and applications, DSP technologies offer dedicated, predictable and scalable performance for resource-intensive functions like echo cancellation, voice quality enhancement (VQE) and VoIP codec.  The DSP offers 128ms echo cancellation and voice quality enhancement (VQE) on all voice resource channels.  These features together deliver superior conferencing quality and typically produce 10% higher ASR accuracy than the technology without these two features.
