Why are Service Providers deploying Veraz ControlSwitch?
It Works!
Architecture Compatibility with IMSCentralized Management
Network components can be distributed globally but they can be managed as onefrom a single location with features such as end to end call tracing and single CDR
Extensive Reporting and Troubleshooting Tools
Geographic Redundancy and Distributed Architecture System components can be distributed geographically for scaling and high
availability
ControlSwitch runs on Off-the-Shelf Sun hardware providing investment protection
Cost Effective Scalability
Can start small and grow with incremental upgrades without any fork lift upgrades
Multi-Protocol Connectivity Provides transparent connectivity between any TDM Nodes (ANSI/ETSI ISUP, PRI,
CAS) and IP Nodes (H.323, SIP, MGCP, H.248)
Most Flexible and Easy to Customize Routing
Service Customization using Veraz Services Framework
New customized Communication Services using XML based service creation tool togenerate New Revenue for Service Providers
