The Grandstream Networks HT812 v2 is an advanced analog telephone adapter with two FXS ports, designed to connect analog phones to VoIP systems. It supports two SIP profiles simultaneously, allowing you to manage two lines easily and effectively.
This model includes a built-in Gigabit NAT router, capable of handling forwarding speeds of up to 100 Mbps. The two RJ45 10/100/1000 Mbps ports allow for easy integration of the device into your network.
The HT812 v2 uses TLS and SRTP encryption to protect calls and SIP accounts. In the event of a primary server failure, SIP failover kicks in and automatically switches to a secondary server, ensuring service continuity.
You can count on three-party voice conferencing per port, support for fax over IP via T.38, and compatibility with various caller ID formats. It also includes features such as call waiting, transfer, forwarding, hold, and do not disturb mode.
The device supports automatic provisioning via TR-069 and XML configuration files. When used with Grandstream UCM series IP PBXs, it benefits from zero configuration for an even faster installation.
With GDMS, you have free access to a centralized platform to configure, monitor, update firmware, and manage Grandstream devices. Management is secure, with bank-level TLS encryption and two-factor authentication, and can also be done through the mobile app for Android and iOS.
