Sansay's VSXi Session Border Controller (SBC) is a high-performance, software-based solution designed for communications service providers, offering critical functions such as security, network address translation, protocol normalization, and session management. It supports up to 500,000 concurrent calls and 1 million SIP registrations, providing scalability for large deployments. The VSXi facilitates SIP trunking applications by managing Least Cost Routing and NAT traversal requirements. It also offers programmable SIP trunking capabilities, allowing for authenticated and unauthenticated trunks with features like extension-to-extension dialing, call forwarding, and failover support. Integration with Microsoft Teams is supported through Direct Routing, enabling users to make, receive, and transfer calls between Teams and the public switched telephone network (PSTN). The VSXi can be deployed in cloud environments and includes APIs for integration and customization.

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.
