Class 4 Trunk Replacement

If your business is looking to migrate from TDM trunks to VoIP trunks, follow the leader: Sonus. We’ve helped many of the world’s largest service providers and wholesale carriers move to more efficient IP-based communications in their core and Class 4 networks. From the very beginning, Sonus did things differently. We built a centralized softswitch architecture that allowed service provides to manage their entire network as a single, logical switch—saving our customers millions of dollars in OPEX costs. We built migration-friendly gateways that transitioned seamlessly from hybrid TDM/IP switches to pure IP softswitches to powerful session border controllers. We bridged SS7-based services with new IP services to create a blended, unified service experience for voice subscribers. And we did it all while achieving 99.999% reliability in our networks.
