Description
The AudioCodes MP1288-288S-2DC is a high-density analog gateway engineered for large-scale enterprise and service-provider environments requiring seamless and reliable integration of legacy analog devices into modern IP communications. With 288 FXS ports, robust survivability features, and advanced SIP interoperability, this platform is ideal for hospitality deployments, campus environments, contact centers, and organizations transitioning to all-IP telephony without sacrificing existing analog investments.
Delivering mission-critical resiliency, the MP1288 provides integrated surge protection, enhanced emergency/elevator phone support, dual DC power inputs, and powerful SBC functionality for secure connectivity to SIP trunks. It supports SRTP on all channels, extensive fax capabilities with T.38v3, SIP header manipulation, and long-haul analog support up to 7.5 km, ensuring unmatched flexibility and operational continuity.
The gateway’s modular 3U chassis and front-to-rear airflow design make it ideal for dense rack environments, while its comprehensive codec support—including G.711, G.729A/B, G.722, Opus-NB, and more—ensures high-quality voice performance across the network. Built to TAA standards, the MP1288-288S-2DC is a secure, scalable choice for organizations demanding reliability at scale.
