Grandstream HT813: Hybrid ATA with 1 FXS and 1 FXO Port

  • The Grandstream HT813 is a hybrid analog telephone adapter (ATA) featuring one FXS port for analog devices and one FXO port for connecting to the PSTN, enabling automatic failover in case of power or service outages. This dual-port design makes it ideal for bridging traditional telephony with modern VoIP systems.

    It supports up to two SIP profiles, includes dual 100Mbps LAN/WAN ports, and offers powerful features like 3-way voice conferencing, T.38 fax support, secure auto-provisioning via TR-069, and failover switching to secondary SIP servers. Security is ensured through strong AES encryption and SRTP.

    With its compact size, ease of configuration, and high-quality performance, the HT813 is an excellent choice for residential users, small offices, or service providers transitioning to VoIP.
