Session Border Controller (SBC)

SBCs are inserted into the signaling and/or media paths between calling and called parties in a VoIP call, predominantly those using the Session Initiation Protocol (SIP), H.323, and MGCP call-signaling protocols.

The perimeter of any network is only as strong as its weakest link and must provide the secure basis required to ensure continuity and quality of your service offerings.

IPVision enables service providers to deliver trusted, first class interactive communications-voice, video and multimedia sessions-across IP network borders. Our solution of session border controllers satisfy critical security, service assurance and regulatory requirements in wireline, cable and wireless networks. Our deployments support multiple applications-from VoIP grunting to hosted enterprise and residential services; multiple protocols-SIP, H.323, MGCP/NCS and H.248; and multiple border points-interconnect, access network and data center with high availability

SBCs integrate signaling and media, performing session-aware call control functionalities. SBCs can be configured as B2BUA, B2BCA, B2BGK or just a simple SIP Proxy. They perform routing policies based on sessions or elements, traffic management assuring QoS levels. They also provide enhanced security measures to avoid attacks, flooding and malformed packets from reaching the core network.

Cloud Native Design

The Perimeta software runs on any platform –public cloud, private cloud, virtualized or COTS hardware – and takes full advantage of today’s standard processors, offering outstanding performance. It can provide transcoding without GPUs or DSPs. And with its patented N + k redundancy model, it removes the need for passive backups that take up underlying platform resources, doubling the utilization of underlying hardware immediately.
Distributed Admissions Manager (DAM) and the Secure Distribution Engine (SDE) allow hundreds of Perimeta instances to act and be managed as a single logical SBC. This means that Perimeta SBCs act in unison to provide maximum security to the network and provide unparalleled centralized intelligence when distributing traffic and making admission decisions related to SLAs and capacity limits.
