Ribbon's C15 Call Controller supports a wide variety of standard protocols, interfaces, and features to concurrently enable both IP and legacy services for Class 5 replacement, including HD voice, Centrex, web portal, mobility, video calling, call logging, integrated voice mail, AMA collection, IP PBX, LNP, E911, and CALEA. The C15 provides integrated SIP call session control, session border control, and TDM gateways for seamless inter-working between VoIP and TDM subscribers. It also integrates with other elements of the Ribbon portfolio including media gateways and session border controllers, to support a broad range of residential and business services.

The C15 reduces CapEx and leverages existing fixed access by connecting to line frames and peripherals of switches such as DMS 10 and DMS 100, as well as MSANs and other IP-based access, enabling operators to effectively discard their TDM switch cores and move customers to the SIP and IMS services cloud.

The C15 serves an important role in establishing trust context in relationship to STIR/SHAKEN and Ribbon Call TrustTM. In the originating network, the C15 provides origination attestation and tagging and in the terminating network, it provides termination verification reporting.

The C15 is one element of Ribbon's portfolio of solutions for rural and regional providers, learn more on our rural & regional service provider solutions page
