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, CenturyLink now uses the Grandstream HT813.
Using an Ethernet cable, connect your laptop or PC to the LAN port on the 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 via a web browser by using the IP address. This DHCP server is turned off and becomes passthrough once the ATA receives its initial configuration from the CenturyLink hosted server.
In a web browser, go to http://192.168.2.1.
Default password is admin.
Once a device has pulled configuration, the password is changed to 235711.
Note: The new password is your indication that the ATA successfully pulled the initial configuration.
