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.
