Description
Ericsson's Session Border Controller (SBC) is a high-performance, virtualized solution aimed at ensuring both security and interoperability between IMS and various networks, managing both signaling and media effectively. It serves as a comprehensive solution for a range of services including Voice over LTE (VoLTE), Voice over Wi-Fi (VoWiFi), Video over LTE (ViLTE), Rich Communication Services (RCS), fixed VoIP, interconnection, and web communication applications. This SBC can be implemented on virtually any x86 hardware across several cloud platforms, such as OpenStack, VMware, and Ericsson NFVI. It is also validated on Ericsson's software-defined infrastructure (SDI) and can be part of standardized industrial solutions. The architecture of the SBC leverages centralized control while managing the media plane in areas of high traffic, which helps to reduce media latency and optimize transmission costs. With its extensive features and convergent capabilities, the Ericsson SBC allows service providers to consolidate their needs into one product, leading to considerable operational expenditure (OPEX) reductions. This unification of services not only enhances efficiency but also simplifies the management of diverse communication solutions for operators.
Description
Kamailio® is an open-source SIP server, which evolved from the earlier OpenSER and SER, and is distributed under GPLv2+, capable of managing thousands of call setups each second. This robust platform can be utilized for constructing extensive systems for VoIP, real-time communication, presence, WebRTC, instant messaging, and various other applications. Additionally, Kamailio is well-suited for scaling SIP-to-PSTN gateways, PBX systems, or media servers such as Asterisk™, FreeSWITCH™, or SEMS with ease. Its extensive feature set includes support for asynchronous TCP, UDP, and SCTP, secure communication through TLS for voice, video, and text, as well as WebSocket compatibility for WebRTC. The server supports both IPv4 and IPv6, offers simple instant messaging and presence capabilities with an integrated XCAP server and MSRP relay, and enables asynchronous operations. Furthermore, it includes IMS extensions for VoLTE, ENUM functionality, DID and least cost routing, load balancing, and routing failover. Kamailio also provides comprehensive accounting, authentication, and authorization features, while supporting a variety of backend systems, including MySQL, Postgres, Oracle, Radius, LDAP, Redis, Cassandra, MongoDB, and Memcached. All these capabilities make Kamailio a versatile choice for modern communication infrastructures.
