Key Features of the Grandstream HT812 Analog Telephone Adapter
Two FXS Ports and Dual SIP Profiles
The HT812 comes equipped with 2 FXS ports and supports 2 independent SIP profiles. This design allows you to run two separate phone lines or a combination of one phone line and one dedicated fax machine simultaneously from a single adapter.
Integrated Gigabit NAT Router
Unlike basic adapters, the HT812 features two built-in Gigabit network ports. With its integrated high-performance NAT router, the device handles routing speeds up to 100 Mbps. This allows you to connect the adapter directly between your modem and computer without slowing down your internet speed.
Carrier-Grade Security Encryption
Data security is built into every layer of the Grandstream HT812. The adapter utilizes advanced TLS and SRTP security encryption technology to protect your voice streams and accounts. This enterprise-level security prevents eavesdropping and protects your network from unauthorized access.
Automated Management and Provisioning
Deploying multiple voice adapters across different office locations is simple. The Grandstream HT812 supports automated provisioning options using TR069 and XML configuration files. It also features zero-configuration setup when paired with Grandstream UCM series IP PBX systems.
