Case Study: Deltathree achieves seamless SIP load balancing and 100% uptime to support business growth with Radware's AFE Solution

Deltathree - Customer Case Study

deltathree, a global provider of SIP-based VoIP services for service providers and consumers, needed a more reliable network infrastructure to support growth of its Hosted Consumer VoIP and reseller channels. The company’s priority was a load‑balancing solution that could handle high SIP and HTML traffic, ensure seamless redundancy and 100% uptime, and reduce manual maintenance and upgrades.

deltathree deployed Radware’s Application Front End (AFE) using advanced layer 4–7 policies; the solution passed capacity and redundancy tests for web, SIP, DNS, TFTP and related services. Radware AFE eliminated traffic surges, server bottlenecks and disconnects, optimized server utilization and preserved uninterrupted user experiences—supporting deltathree’s continued growth and operational reliability.
