Nuera Session Border Controllers and Media Gateways

Nuera’s session border controllers (SBCs) and media gateways are versatile IP communications platforms that connect VoIP and TDM networks.


SBCs are deployed at the border between the enterprise and the service provider. In the enterprise environment, they form an effective demarcation point between the business’s VoIP network and the service provider’s SIP trunk, performing SIP protocol mediation and media handling (interoperability) and securing the enterprise VoIP network. In the service provider core, SBC provide security and protocol normalization. The Nuera SBC family includes a range of platforms that offer cost-efficient SBC and hybrid functionality (SIP to TDM, SIP to SIP).


Media gateways are cost-effective, stand-alone platforms that provide superior voice technology for connecting legacy telephones, fax machines and PBX systems with IP telephony networks and IP-based PBX systems.
