Bridge Your Analog Phone System to a Powerful VoIP Network
The Grandstream HT881 is a high-density analog FXO gateway designed for businesses looking to integrate their traditional PSTN lines with a modern VoIP network. This powerful device allows you to seamlessly connect up to eight analog telephone lines to any hosted or on-premise IP PBX system, making it an ideal solution for medium-to-large enterprises that want to leverage their existing telecom infrastructure while upgrading to the benefits of VoIP. The HT881 features 8 FXO ports, a versatile FXS port for an analog phone or fax machine, and an integrated high-performance NAT router, providing a comprehensive and scalable hybrid telephony solution.
Advanced Features for Uninterrupted Communication
Engineered for reliability and robust performance, the HT881 is packed with advanced features to ensure business continuity. It includes critical lifeline support, which maintains a connection between the FXS and FXO ports during a power outage, guaranteeing that you always have a line for emergency calls. The device supports 3 SIP profiles, offering flexibility and redundancy in your VoIP service connections. For businesses that still rely on traditional faxing, the HT881 provides reliable T.38 Fax-over-IP for efficient and accurate transmission over your IP network.
Uncompromising Security and Simplified Management
Security is paramount in modern communications. The HT881 addresses this with strong AES encryption and unique security certificates per unit to protect all your voice communications. Deployment and ongoing management are streamlined through automated provisioning options using TR-069 and compatibility with Grandstream's Device Management System (GDMS). This allows for a centralized interface to provision, manage, monitor, and troubleshoot devices, significantly enhancing operational efficiency. With features like a failover SIP server that automatically switches to a secondary server if the main one fails, the HT881 is built for high availability and superior voice quality.
