When procurement rules and voice architecture both matter, the AudioCodes Mediant 800C gives teams a compliant path forward. This TAA-compliant gateway is built around two E1/T interfaces, making it a strong fit for organizations that need to connect legacy trunks or regional telephony circuits into SIP-based communications environments. The value here is precision. Instead of oversizing a platform for a narrow requirement, the Mediant 800C focuses on the interfaces that matter for regulated deployments. That makes it well suited to federal, public sector, and enterprise projects where approved sourcing and telephony interoperability are part of the buying decision. For infrastructure teams, this model helps preserve existing voice investments while aligning with current network standards. It is the kind of gateway selected when the deployment must be documented, compliant, and technically clean from day one. If your project depends on E1/T connectivity and TAA status, the Mediant 800C is built to fit that brief without excess complexity.
