SmartNode 5531 Overview
The SmartNode 5531 Enterprise Session Border Controller (eSBC) and Integrated Access Device (IAD) (see
) comes with built-in security features such as SIP TLS, SRTP, stateful firewall, and secure provisioning
to protect the LAN networks from fraud strikes out of the Internet. For survivability use cases the BRI ports
can be used for local PSTN breakout. The BRI ports can be used to connect legacy equipment to any VOIP
network as well. Like any other Trinity device, the SN5531 comes with the built in WEB Wizard for ease of
use.
