1 FXS Port & 1 FXO Port

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. FXO (Foreign Exchange Office) on the other hand is the port that receives the analog line. It is the plug on the phone or fax machine or the plug(s) on your analog phone system. It delivers an on-hook/off-hook indication (loop closure). The Grandstream HT813 VoIP Gateway Kuwait is equipped with 1 FXS port and also 1 FXO port which allows 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

The Grandstream HT813 Kuwait is equipped with 1 FXS port 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.

Fax Support

The Grandstream HT813 Kuwait 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

Grandstream HT813 Kuwait provides a reliable and secure cloud service to deliver connectivity to its users at cheaper maintenance costs while enhancing operation and maintenance efficiency. 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 HT813 VoIP Gateway in Kuwait uses this feature to eliminate delays, thus maximizing productivity.
