Lumen help
Follow the instructions below to configure the profile rule for your Grandstream HT503 ATA (analog termination adapter), it provides one analog FXS port and one FXO port.
Important: The Grandstream HT503 has been discontinued. Use this article for configuring your existing equipment. If you need a replacement or additional ATA, Lumen uses the Grandstream HT813.
To configure your Grandstream HT503 ATA:
Note: The ATA will give you an IP address initially due to the default setting in the device configuration of NAT and DHCP server. The IP address of the unit will be 192.168.2.1 by default and can be accessed with a web browser by using the IP address. This DHCP server is turned off and becomes a passthrough after the ATA receives its initial configuration from the Lumen hosted server.
