Grandstream HT813 Documentation (Datasheet, Manuals, Firmware)

The Grandstream HT813 is a hybrid adapter with one FXS port for an analog phone and one FXO port for a PSTN line. It bridges a VoIP system and an existing phone line, and its FXS port hard-relays to the FXO line during a power outage so calls still work. It supports two SIP profiles, T.38 fax, TR-069 and GDMS management, and AES encryption with a per-unit security certificate.
