[ Grandstream ] This guide is about the Grandstream HT802 2-Port Analog Gateway.
This unit is an Analog-to-SIP convertor, allowing you to connect a regular analog phone to our VoIP Services. This is a dual-FXS unit, meaning it can do analog voice phones, but not fax machines/devices (FXO).

- Important note about Analog : Due to the way analog phones work, every phone connected in chain to this one physical port on the Grandstream 802 will 'ring' when this extension is called. Likewise, only one phone on this chain can be used at a time. This is the nature of 'analog', how phones were for most of the 20th century.
