It's a fact, most enterprise IP-PBXs just can't deliver the scale and reliability of carrier-grade SL-100 or CS2100 deployments. However, users need modern communication tools that these 10 or even 20-year-old platforms weren't designed to provide. Telecom managers have been caught in the middle, forced to choose between richer services or reliability. Stop compromising! Ribbon's Nortel heritage means we still have the teams that originally developed these platforms and continue to innovate. Legacy hardware has given way to fully virtualized solutions that are far more cost-effective to operate and deliver modern UC experiences. SIP-based device support, web interfaces, and UC clients, and more are part of the solution. Of course, we offer support for legacy phones and infrastructure. All without giving up the carrier-grade resiliency you've come to expect.

Enjoy the peace of mind that comes with a fully supported solution and a fully committed product roadmap that extends investments for years to come.

Migrating to a Unified Communication Server

Ribbon dramatically reduces costs using virtualized elements that cost less to manage and operate. Reduce footprint, energy costs, and legacy complexity with a transformed IP network that consolidates and simplifies operations. Avoid vendor lock-in with standard SIP-based endpoints and reduce operating expenses and improve service agility with SIP trunks.

CS2100 Software

Ribbon's SE 19 software extended the value of CS2100 investments, assuring ongoing Ribbon support, security enhancements, new capabilities, and additional migration paths. Ribbon has a proven track record of supporting CS2100 customers with impactful software updates, service and support contracts, and experienced professional services engagements. We've engaged with our CS2100 customers and reseller partners to find ways to deliver innovative new solutions including:

  • New hardware options for end-of-life elements
  • Best-in-class SIP phone support that emulates legacy TDM services
  • Support for industry-standard UC clients for desktop and mobile
  • Market-leading contact center integration

New Migration Options - Virtual C20

SE 19 provides a graceful migration point for organizations that need to migrate off a CS2100 core. Many CS2100 deployments are saddled with legacy servers and hardware platforms that need to be refreshed. Ribbon's Virtual C20 solution offers a logical next step and eliminates reliance on proprietary, chassis-based, server hardware. SE 19 simplifies the migration process to a Virtual C20 platform that runs on a variety of commercial servers, dramatically reducing footprint and costs. Virtual C20 retains the resiliency, scale, and features CS2100 customers require, without the substantial proprietary hardware they've had to endure. Migrating a CS2100 platform to a Virtual C20 means lower migration costs near term and reduced operational costs long term.

Enabling the Power of SIP

Upgrading a CS2100 delivers far more than extending the status quo. SE 19 opens the door to the latest revision of Ribbon's Application Server to deliver integration to industry-leading SIP phones and devices (access, control, emergency pedestals, etc.).
