Call Controllers

Call session controllers are critical switching elements that enable voice and multimedia calls and sessions to traverse networks, enabling a seamless user experience.  They are the core components in advanced architectures like IMS.

GENBAND is the market leader in this category with three state-of-the-art, carrier class platforms: C20, C15, and C3 Call Session Controllers.  These platforms are used by service providers and enterprises to grow revenue, offer new voice and multimedia services, transform or replace costly legacy switching, and converge disparate mobile and fixed networks. 

Class 4 and Class 5 Switch Replacement

GENBAND’s Call Session Controllers allow service providers to grow revenue and deliver HD voice and IP multimedia services to their subscribers by replacing or reusing the legacy Class 4 and Class 5 switches in the network.

Legacy Switch Migration (Nortel DMS Switch, EWSD and Others)

GENBAND’s Call Controller portfolio enables service providers to consolidate and modernize their existing network of legacy switches, including Nortel DMS 100, DMS 200, EWSD Switch and others, and offer all new IP services to their subscribers.
