Virtual C20 Data Sheet

2024-11-28
●Service providers are facing unprecedented challenges in their voice businesses. Over-the-top (OTT) providers are beginning to skim-off customers with freemium VoIP offers. Business customers are pursuing Unified Communications services, increasingly via the cloud and OTTs. At the same time, “voice” has stepped aside for messaging, texting, email, and social networking – making complex, multi-component voice architectures seem contrary to what service providers need to compete.
●Ribbon Communications’ C20 Call Controller leads the global market in transforming networks, and it is the core services and switching infrastructure platform for tens of millions of users around the world across fixed, mobile, and cable operators. The C20 simplifies complex architectures like IMS by efficiently delivering voice and multimedia services that enable new services, revenue growth, and customer retention while providing customer-at-a-time migration.
●Overview:
■The C20 is the product of more than a decade of focused development and investment in intelligent design and services innovation. The new Virtual C20 is the next generation, fully virtualized, C20 call server solution. The Virtual C20 is built using an application Virtual Machine (VM) model where the Call Agent runs on Intel processors. This advancement allows the Virtual C20 to run on a much wider variety of Rack Mount Servers (RMS) since an embedded PCI card with Motorolla processor is not required. Virtual C20 replaces legacy TDM infrastructures with ease, substantially reducing power consumption and footprint by 90% or more. Due to its wide- spread use in service provider networks large and small, it has network-proven capabilities to facilitate back office integration and transformation.
■Because the C20 is so flexible and versatile, it provides essential switching and subscriber services for many of Ribbon’s network transformation solutions like IMS, SIP Trunking, IPX,Peering, and Intra-Network Interconnect. The C20 also provides inherent connectivity to the Ribbon Application Server, enabling SIP and IMS-centric services like multimedia Unified Communications. In order to support such a broad set of solutions, it has intelligent capabilities to handle both legacy and IP voice and multimedia services across many geographies and international standards. It also has widely-proven interoperability with the largest number of end user devices, access platforms, and core elements.
■The C20 is at the core of many service providers’ plans for network transformation. It is the key call control element providing switching, media gateway control, signaling and protocol interworking, emergency services, lawful intercept, media server,customer data store, billing, and end user voice and multimedia services support. For service providers that plan on eventually deploying an IMS solution, the C20 and MGCF facilitates migration to IMS by providing comprehensive AGCF support.This ability to serve in both Next Generation Networks and IMS architectures is efficient and powerful, enabling investment protection and services continuity, and allowing operators to migrate customers at their own pace.
