Cisco 7970 - Directory key returns "HTTP File Error"

Hello!

I have a few Cisco 7970’s attached to my FreePBX/Asterisk server, which are all working fine- except for the directory.

I have created xml files, per Cisco’s requirements, for the menu and the directory listings. I have also created a PHP file named authenticate.php that echos AUTHORIZED.

These are all on a web server, and I have updated the endpoint’s config file to point to the URL. However, when I press the Directories key I get, “HTTP File Error”. I have double-checked privileges too.

Has anybody else experienced this issue? Anyone have any advice in terms of resolving this error?

Nobody else using 7970 endpoints with the directory feature?
