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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e1 FXS + 1 FXO port\u003c\/strong\u003e: connect an analog phone and a PSTN line\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePower-outage lifeline\u003c\/strong\u003e: FXS hard-relays to the FXO line\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eIntegrated NAT router\u003c\/strong\u003e with LAN and WAN ports\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eT.38 fax\u003c\/strong\u003e with automatic fallback to G.711 pass-through\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eTR-069 and GDMS\u003c\/strong\u003e cloud management\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eLines:\u003c\/strong\u003e 2 SIP profiles\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePhone ports:\u003c\/strong\u003e 1× RJ11 FXS, 1× RJ11 FXO (PSTN) with lifeline\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eNetwork:\u003c\/strong\u003e 2× 10\/100 Mbps RJ45 (LAN and WAN), integrated NAT router\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eLEDs:\u003c\/strong\u003e Power, LAN, WAN, FXS, FXO\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eTelephony features:\u003c\/strong\u003e caller ID, call waiting, flash, blind and attended transfer, call forwarding, hold, do not disturb, 3-way conference per port\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWorks With\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eAny standard SIP platform: 3CX, FreePBX\/Asterisk, RingCentral and most hosted VoIP providers that allow third-party devices\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eGrandstream UCM series IP PBXs, with zero-configuration provisioning\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eGrandstream GDMS cloud management and TR-069 for remote provisioning\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eKeeping a copper PSTN line as backup to a VoIP service\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eBringing an existing PSTN line into an IP PBX\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eSites that need phones to work during a power outage\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWhat’s in the Box\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003eGrandstream HT813 (HT813)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003ePower adapter\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eQuick installation guide\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eRelated guides\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/resilient-tec.com\/collections\/phones\"\u003eAll VoIP phones and adapters\u003c\/a\u003e — every IP phone, ATA and headset we carry\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grandstream","offers":[{"title":"Default Title","offer_id":67998295130212,"sku":"HT813","price":95.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0767\/3482\/4548\/files\/ht813_right_web-website.png?v=1793903082","url":"https:\/\/resilient-tec.com\/products\/grandstream-ht813-ht813-new-1-fxs-1-fxo-voip-gateway-with-pstn-lifeline","provider":"Resilient Tec","version":"1.0","type":"link"}
