VoIP Adapter Grandstream HT813

The Grandstream HT813 is a hybrid analog telephone adapter (ATA) with one FXS port for a phone, fax machine or other analog device, and one FXO port for a regular PSTN phone line. This combination lets users place and receive calls through the PSTN line, also remotely, and during a power outage the FXS port is hard-relayed to the FXO line so the phone keeps working (lifeline).

The adapter has two 10/100Mbps network ports, WAN and LAN, with a built-in NAT router, two SIP profiles, G.711, G.729, iLBC and Opus codecs, T.38 fax and 3-way conferencing. Security includes SRTP, TLS and HTTPS with a unique security certificate per unit, and automated provisioning works through TR-069 or an AES-encrypted configuration file.

Key features

• Power-outage lifeline - During a power outage the FXS port connects directly to the FXO line, so calls can still go through the PSTN line.
