If you operate a TDM network you know, the time is coming… Your equipment is aging, your technicians are retiring, and the spares are sparse.  With Ribbon's call controllers, you can accelerate your network modernization. 

Ribbon acquired Nortel's carrier business in 2010. Our people have decades of in-depth experience deploying and migrating DMS and CS 2000 offices. Over the past decade, our professional services teams have replaced over 30 different switch types, all while keeping the regulators happy and without affecting subscribers.  Ribbon's solutions will integrate into existing front and back office systems, saving providers time and money in the transformation process. It's no surprise that Tier 1, Tier 2, and Tier 3 service providers globally rely on Ribbon to transform their network.

Ribbon has successfully transformed Mobile, Local Exchange Carriers (LECs), Competitive Local Exchange Carriers (CLECs), Rural providers, MSOs, IPX providers, UCaaS providers, including;

  • Over 4,000 End Offices Migrated
  • Over 55M Ports (lines and trunks) Migrated

Ribbon's Call Controllers use the latest virtualized software and COTS hardware to enable providers to dramatically shrink their carbon footprint, shrink infrastructure costs, and simplify ongoing support. With Ribbon, moving to modern software doesn't force providers to rip and replace their last mile. Ribbon can help providers transition their legacy last mile, at their own pace, with the industry's most complete and fully integrated gateway portfolio. Of course, the same Ribbon solutions support full VoIP implementations to maximize RoI.

Ribbon enables service providers to deliver mobile, fixed, long-distance, business, and consumer voice services. Our call controllers lead the global market in transforming networks and are the basis for core services and switching infrastructure for millions of users worldwide.
