Training Session Border Controller (SBC) Essential Architecture and Operations

(ecgt2162)

Session Border Controllers (SBCs) are a major part of Voice and Video networks used by Mobile, UCaaS, and other Service Providers. Learn the purposes of SBCs, how they relate to other call routing and security components. Discover how bad actors (hackers) attack networks and how SBCs are deployed to mitigate the risk. You'll see how they address NAT issues with a detailed look at IP addresses and port numbers, and are used for SIP Peering (Network-to-Network Interface, NNI) connections. This material applies to Oracle Acme Packet SBCs, Sansay, Metaswitch Perimeta, Ribbon, Audiocodes, and others. Graded Exams; Certificate provided. 1 class session / 2 PDH.
