Cisco Session Border Control (SBC) is an IP multimedia security and operational enhancement function for session-oriented IP services, based on SIP/H.323/H.248 signaling. It enables direct IP-to-IP interconnect between multiple administrative domains for session-based services, providing protocol internetworking, security, admission control, and management. It enables direct IP-to-IP peering between service providers, and between service providers and their business and residential customers. The most common SBC deployment is Voice over IP (VoIP) peering between service providers by converting IP to public switched telephone network (PSTN) and using existing PSTN peering infrastructure.
What makes Ribbon SBCs stand apart from the competition? Maybe it’s because the world’s most demanding networks have trusted Ribbon to deliver high-quality SIP communications for more than 20 years. Or maybe it’s because we offer more choices than anyone else, with unique SBC models that scale from small businesses to the world’s largest service provider networks. But more than likely it comes down to something simple - Ribbon SBCs simply work.
We monitor all Session Border Controllers (SBC) reviews to prevent fraudulent reviews and keep review quality high. We do not post reviews by company employees or direct competitors. We validate each review for authenticity via cross-reference with LinkedIn, and personal follow-up with the reviewer when necessary.
