3. Connect Your Device

Step 1 —Connect your phone(s).

Plug a standard RJ-11 telephone cable into a Phone port and connect the other end to your analog phone, cordless phone base, or fax machine.

Step 2 —Connect to the internet.

Using the included Ethernet cable, connect the WAN port to your router, switch, or modem.

Step 3 —Connect power.

Plug the included 12V power adapter into the DC 12V port and into a wall outlet. The Power LED will light up and flash while booting.

Step 4 —Wait for startup.

Allow 1–2 minutes for the adapter to boot and register with your VoIP service. The device is ready when the Power, WAN, and Phone LEDs are all solidly lit blue.

Step 5 —Test.

Pick up the phone and listen for a dial tone. Try making a test call to confirm everything is working.

💡 Optional — LAN port: You can also connect a computer to the LAN port. When used this way, the HT812/HT814 acts as a router and serves DHCP addresses to connected devices. Make sure NAT Router mode is enabled under Web GUI → Basic Settings → Device Mode.
