Avaya SG208 Security Gateway Unit

The Avaya SG208 Security Gateway Unit is a dedicated security gateway appliance in Avaya’s SG family, designed to integrate with Avaya communications environments and provide a controlled edge for voice traffic. Documented alongside other SG models such as the SG203, the SG208 is deployed at the network perimeter to help secure connections between enterprise networks and external SIP trunks or service providers. Activation typically requires an Avaya Remote Feature Activation (RFA) license file specific to the SG208, according to Avaya licensing notes, and the model is listed in official support materials as a Security Gateway option. Historical trade coverage has cited the SG208 with a list price around $15,000, reflecting its enterprise-class role, while independent listings also refer to the unit as the SG208 Security Gateway. Availability and documentation such as configuration guides and Avaya Solution & Interoperability Test Lab references confirm its place in the SG security gateway lineup, supporting integration with Avaya IP PBX deployments.
