Grandstream HT812

El Grandstream HT812 es un adaptador telefónico analógico de dos puertos que permite conectar teléfonos y máquinas de fax tradicionales a una red VoIP moderna sin modificar su uso habitual. Gracias a sus dos puertos FXS, puedes conservar los dispositivos que ya conoces y confías, mientras disfrutas de la flexibilidad y el ahorro que ofrece el servicio SIP.

Incorpora un router NAT Gigabit con dos puertos Ethernet, lo que permite que el adaptador funcione como el núcleo de una pequeña red, compartiendo la conexión de alta velocidad con otros dispositivos y reduciendo la necesidad de hardware adicional. Ya sea colocado en un escritorio doméstico o en un rack de comunicaciones de una pequeña oficina, su configuración es sencilla gracias a la provisión automática mediante TR-069 o archivos XML descargables.

Las llamadas se mantienen protegidas mediante cifrado TLS y SRTP, garantizando la privacidad incluso cuando las comunicaciones atraviesan redes públicas. La gestión centralizada a través del Grandstream Device Management System facilita a los equipos de TI o proveedores de servicios la supervisión de grandes despliegues, la aplicación de actualizaciones y la resolución de problemas desde cualquier lugar.

Con soporte para conferencias de voz de 3 vías y Fax-over-IP T.38, el HT812 va más allá de las funciones básicas de marcación. Las pequeñas empresas pueden realizar reuniones rápidas en equipo, mientras que los trabajadores remotos pueden enviar contratos por fax sin necesidad de buscar una línea telefónica. Además, el adaptador se integra de forma natural con las centralitas IP Grandstream UCM, creando una plataforma unificada para entornos que combinan terminales IP y analógicos.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
