Carrier Grade UC
Sigma® Core software is a Carrier-Grade Unified Communications (UC) platform from REDCOM that can be located on-premise or in the cloud. Sigma Core software delivers a robust suite of features and can operate as a Virtual PBX, Class 4/5 core, and an International Gateway. The software’s focus on the use of industry-standard protocols enables interoperability with a variety of devices and platforms from many manufacturers and service providers, including third-party call control platforms, session border controllers, gateways, and more.
Cap. Grow. Enhance.
Most voice carriers have long been on the weary road of migrating from legacy TDM hardware to software-centric Next Generation customer-focused services. After a decade of industry trial and error, it has become clear that a Cap and Grow strategy is the most viable solution for IP network transformation.
Few carriers are in the enviable position to cap their entire network and invest in an entirely new overlay network. Furthermore, successful voice carriers have substantial investment in fully functional network assets for which newer technologies fail to offer significant gain.
Clearly, investment in growth and service enhancements should, when possible, be based on the latest technologies—but does it always make sense? Does internet access have to be via FTTH or does it make better sense to re-use the copper network with DSL? Does a rush to replace TDM trunking with SIP trunking require the wholesale replacement of core equipment, prepaid platforms, and voice mail? While each case is unique, a sensible Cap and Grow strategy allows for a planned, metered approach.
The Promise: inexpensive, powerful, and agnostic
Core switches used to be large, heavy hardware-based devices that were proprietary, complicated, expensive, and power hungry. The move to software-centric solutions eliminated that, but brought its own suite of problems—lack of interoperability with the legacy network, dubious quality, and vendor instability. With REDCOM Sigma Core software, all that has changed.
Sigma Core software by REDCOM was designed from the start as a carrier grade software-centric solution with the reliability, flexibility, and ease of use for which REDCOM products are renowned. Sigma Core not only includes a carrier-grade switching and translation matrix (ideal for migration from propriety remotes to powerful, yet agnostic BLCs and MSANs) but also a full suite of Unified Communications features to fulfill user demand.
As with all REDCOM products, a broad spectrum of features, along with extensive configuration capabilities, enable Sigma Core to operate as a stand-alone PBX, a Hosted PBX solution, a Class 4/5 core, even an International Gateway—or all-in-one!
Transforming to Virtual Networks
One of the greatest benefits of a software-only voice call control core, such as REDCOM’s Sigma Core, is that it runs on relatively inexpensive servers and is vendor agnostic. Thus the price of a new “switch” is effectively the price of software, plus a server. And the financial savings continue long into the future. Gone are the days of stretching out the life of discontinued hardware platforms; now, just move the software to a new server! Virtualization takes this a step further by allowing you to stack multiple virtual machines on to a single physical server, thus making your investment in hardware go even further.
Sigma Core, REDCOM’s carrier grade virtual voice core, includes traditional wireline telephony control for IP connection to BLC systems, thus enabling impressive new subscriber income via a bundled package of phone service, Voice Mail, and DSL.
Sigma Core also offers two of the latest revenue generating business-centric feature packages: Carrier Grade Unified Communications and Virtual PBX. With businesses wanting to divest themselves from PBX hardware ownership, and service providers able to take over those responsibilities, Sigma Core’s Virtual PBX is a win-win for carriers and business customers. And with UC services such as conferencing, single-number service (Find Me Anywhere), Presence, integrated Voice Mail, and Wi-Fi mobility, carriers can offer business customers the features they demand from next generation PBX services.
With a vision of business and network transformation, rather than wholesale replacement, REDCOM’s full suite of TDM, hybrid, and virtual solutions enables carriers to select the technology and path that is right for them.
Taking the Next Step
Many voice service providers find themselves saddled with an aging and unsupported first generation hybrid switch (and a variety of other TDM and IP network devices). For them, the quest for a next generation virtual core may not be driven by service enhancement, but by preparation for replacement before catastrophic failure.
Service providers fortunate enough to own currently-supported hybrid switches (such as REDCOM’s HDX and SLICE 2100) now have the option to continue deployment using more traditional switching cores and software, or deploy these new services with REDCOM’s carrier-grade Sigma Core software.
Keeping in mind that virtually all established service providers’ networks are at some level of transformation from TDM to IP, and are under pressure to produce more revenue, the Cap and Grow capabilities brought by REDCOM’s Sigma Core are timely.
Greenfield deployments are a natural drop-in fit for Sigma Core. Being capable of Cloud-hosted virtual services, Sigma Core meets the needs of Managed Service Providers (MSPs) by providing a Unified Communications and Virtual PBX core. In the likely event that connectivity to legacy networks is required, REDCOM’s hybrid HDX and SLICE 2100 platforms provide a comprehensive connectivity solution.
That said, a Cap and Grow strategy using Sigma Core is not unlike a Greenfield deployment. Successful voice carriers can deploy Sigma Core and move customers when and where it makes sense as time and assets allow.
With Sigma Core’s virtually unlimited scalability, carriers can start with a small Next Gen service base and invest in growth as permitted. As customers are migrated to Sigma Core, the legacy equipment can be decommissioned. Once the full service area is hosted by Sigma Core, the carrier has a truly carrier-grade virtual Unified Communications core with a comprehensive suite of revenue-generating features as well as a roadmap to easily implement future developments.
