OpenTouch Session Border Controller
The OpenTouch Session Border Controller (SBC) by Alcatel-Lucent Enterprise is a highly secure software solution designed to protect SIP trunks and enterprise communications. It serves as the demarcation point between the enterprise and SIP trunking providers, safeguarding against malicious VoIP attacks, SIP denial of service, fraud, and eavesdropping. The OpenTouch SBC offers secure and scalable SIP/media connectivity, including audio transcoding and network address translation (NAT) traversal for audio and video communications. It ensures cost-effective, secure conversations over the internet and with SIP service providers. The SBC features web-based management with built-in configuration templates, allowing settings and protocol adaptations for certified SIP trunking providers to be configured in a few clicks. It provides cost-effective interoperability by offering protocol adaptations for many SIP trunking providers.

Cisco Unified Border Element (CUBE)
Cisco Unified Border Element (CUBE) is an enterprise-class Session Border Controller (SBC) that facilitates secure, scalable, and flexible voice and video connectivity between enterprise networks and service provider SIP trunks. It performs four critical functions: session control, security, interworking, and demarcation. CUBE supports signaling interworking between SIP and H.323 protocols, media interworking for DTMF, fax, modem, and codec transcoding, as well as address and port translations for privacy and topology hiding. It also provides billing and call detail record (CDR) normalization, quality-of-service (QoS) and bandwidth management, and media services such as media forking and proxying. CUBE can be deployed on Cisco routers or as a virtualized solution on Cisco UCS servers, supporting centralized, distributed, or hybrid deployment models.

Nokia Session Border Controller (SBC)
Nokia's Session Border Controller (SBC) secures signaling and control media crossing the edges of the IMS network. It sits at the edge of access networks to secure any type of IP access and deliver all IMS services. It also sits on the edge of peering networks to support roaming, IMS interconnection, or corporate SIP trunking scenarios. The SBC provides functions such as encryption/decryption of bearer traffic, firewall and topology hiding for security, media handling and transcoding, SIP interworking, and NAT traversal. It can be deployed as a standalone SBC or as part of Nokia’s VoLTE/VoWiFi solution. For VoIP services provided to residential and enterprise customers, the SBC offers DoS/DDoS protection, topology hiding of the network from the access, NAT traversal, and codec support for G.729, G.722, and T.38 Fax. In a VoLTE core network, it controls access and allows mobility, providing an EVS codec and supporting eSRVCC, VoWiFi, NPLI, S8HR roaming, and more.
