VoIP/SIP Application Delivery Controller

SIP Service Delivery Guaranteed

Radware’s SIP Director guarantees Session Initiation Protocol (SIP) service delivery. SIP Director is a comprehensive SIP Application Delivery Controller (ADC) for SIP value-added application vendors, Telecom Equipment Manufacturers (TEMs) and System Integrators (SIs). SIP Director is designed to work with a wide range of applications across all IMS network layers from the Service Plane through the Control and Signaling Plane to the Transport Plane. SIP Director is also optimized for pre-IMS networks and entities including softswitches and SBCs.

Radware’s VoIP/SIP ADC solution delivers the intelligence needed to address the VoIP/SIP service delivery requirements of carriers and operators deploying today's VoIP services. Radware’s solution for VoIP/SIP service continuity and optimization provides

• High availability through local and global clustering, health monitoring and optimal call completion
• Scalability through unlimited call capacity, traffic acceleration and performance optimization
• Enhanced interoperability through transport and protocol conversion and mitigation
• Unmatched flexibility through an easy to use configuration with no scripting or coding required
• Security providing user and network protection and privacy enablement
• Reduced time-to-market through out-of-the-box carrier grade compliance enablement

The business benefits include

• Service continuity, enhanced user experience and server optimization across all network layers including Service Plane, IMS and pre-IMS core network implementations as well as border elements
• Significant OPEX/CAPEX savings due to core and back-office design simplification and optimized resource and server allocation
