High-quality voice transmission and features

The Grandstream HT814 V2 provides exceptional voice transmission quality thanks to support for wideband HD codecs such as G.722 and Opus**, which ensure clear and natural sound without noise.

Reliable connection and security

The device is equipped with two gigabit network ports (10/100/1000 Mbps), which ensure fast and stable connection to the Internet and network. The built-in NAT router optimizes traffic and protects the network from attacks.

In addition, each unit has its own security certificate, which increases the trustworthiness of the device.

Easy installation and management

Automatic provisioning via TR-069 with AES encryption enables easy installation and management of the device, which will be appreciated especially by IT administrators in mass deployment. Support for protocols such as HTTP, HTTPS, SSH and TFTP further facilitates configuration and monitoring.
