Additional Information

For provisioning, see How to Provision a Grandstream HT8xx ATA.
WAN (Internet LED) Connects the ATA to your router, switch, or modem using an Ethernet RJ45 network cable. This indicates a network connection but not access to the internet.
The ATA phone ports can register without a phone being connected.
To test if the ATA is recognizing a phone is connected take the phone off the hook (lift receive/press call button). if the port light that the phone is connected to starts to flash it sees the phone, if not try another handset.
If no phone is available or the phone not connecting. ensure the laptop is connected to the same network, open CMD, and run arp -a. This will show the devices on the network, their Mac addresses, and the IPs given to them.
