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
