Grandstream HT818 Features

8 FXS Ports

FXS stands for Foreign Exchange Subscriber or Foreign Exchange Station. This port in gateways is used to connect an analog endpoint like a fax machine or an analog phone. A device that has an FXS port is capable of allowing an analog device to connect to a VoIP network. The Grandstream HT818 VoIP Gateway Ghana is equipped with 8 FXS ports which allow for easy connection of your analog device to a VoIP network so that you can enjoy making and receiving fast calls over the internet.

3-Way Voice Conferencing per port

The Grandstream HT818 VoIP Gateway series is equipped with 8 FXS ports, each of which supports 3-way HD audio conferencing. This enables you to seamlessly connect and collaborate with colleagues from different geographical locations. It is a cost-effective means of communication that maximizes efficiency as well as boosts productivity.

Integrated NAT Router

Grandstream HT818 VoIP Gateway Ghana comes with an integrated NAT router with dual Gigabit Ethernet ports which allow you to share a broadband connection between multiple devices on your LAN without interfering with connection speed.

Fax Support

The Grandstream HT818 VoIP Gateway Ghana is configured to support T.38 Fax which enables you to create Fax-over-IP. 38 is an ITU protocol that dictates how fax audio traverses a packet-switched network, such as the Internet or a company’s LAN/WAN, reliably. In order for fax audio to traverse a packet-switched network like the Internet, the analog signal used by fax machines must be converted into digital packets.

Cloud Management

The cloud service on the internet enables customers to gain direct access to Grandstream devices available on private networks such as IP-PBXs, audio gateways, and IP phones, therefore allowing simple remote maintenance and management of Grandstream devices. This kind of cloud service is specifically designed to meet the needs of large-scale installation, configuration, and maintenance and operation. Auto-provisioning and configuration backup, online update, real-time monitoring and alert enable users to achieve efficient operation and maintenance, thus maximizing productivity in organizations.

Layer 2 & Layer 3 QoS Control

Quality of Service (QoS) is a strong feature that is integrated into routers and switches so as to control traffic flow thus delivering an overall smooth performance improvement for critical network traffic. It simply prioritizes more important traffic by letting it pass first. Whenever there are high volumes of traffic, the Grandstream HT818 VoIP Gateway in Ghana uses this feature to eliminate delays, thus maximizing productivity.

Automated – Provisioning – TFTP/HTTP/HTTPS

The Grandstream HT818 VoIP Gateway Ghana has the ability to deploy an information technology or telecommunications service by using embedded pre-deﬁned procedures that are carried out electronically without requiring any human intervention, thus making it very reliable and convenient.
