Grandstream HT818 8-Port FXS ATA with Gigabit NAT Router

The Grandstream HT818 is a powerful VoIP gateway with 8 FXS ports and an integrated Gigabit NAT router that connects analog phones, fax machines and intercoms to an IP PBX or a SIP service provider. It suits small offices, branches and homes that move to VoIP while keeping analog equipment, and it can be expanded by peering with another FXS gateway.

The adapter supports 2 SIP profiles, wide-band codecs including Opus and G.722, T.38 fax and 3-way conferencing per port. AES encryption with a unique security certificate per unit and automated TR-069 provisioning allow secure volume deployment. This is the original model of the HT8xx series, still listed on the manufacturer's website.
