Typical Applications
Being a flexible system, RSF1000 may be used in variety of telecom applications such as:
The "Brain" of your VoIP Network
Provider gets possibility to easily manage its VoIP gateways, as well as to access useful features, including:
Management of authorization rules of VoIP-gateways
Setting up call routing rules
Provisioning of compatibility for H323 and SIP- equipment of various vendors
Security and load planning of VoIP-traffic by using optional RTP-proxying
Communication with your billing system using RADIUS protocol
When using RTP-proxying RSF1000 provides a single entry point for VoIP traffic to its clients and other providers. This possibility provides reliable methods of disguising network structure thus protecting commercial interests of the parties. Unified IP address for both parties available (clients - provider). All other devices are hidden.
Integration of Equipment With Support of Different Protocols
One of the most important features of RSF1000 is its ability to support widely accepted signaling IP-protocols - SIP and H323. The system provides transparent converging of one protocol into another, thus allowing performing calls from one type of equipment to another.
Note: The system has integrated support of SIP to H323 conversion for H323 "slow start" variant as well.
