Fax Support

The Grandstream HT812 Analog Telephone Adapter Dubai is configured to support T.38 Fax which enables you to create Fax-over-IP. 38 is an ITU protocol that dictates how to 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.

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 HT812 VoIP Gateway in Dubai uses this feature to eliminate delays, thus maximizing productivity.
