Problems with Obtain/Register Digium Phone page

I am having problems with problems with Obtain/Register Digium Phone page. It displays a blank page. Please help.

Which page is blank? What’s the URL?

http://[MYIPADDRESS]/admin/config.php?type=setup&display=digiumaddons&page=add-license-form&addon=dpma

You don’t have the Digium Addons installer module installed.

If your distribution doesn’t include that installer, you can go install a license via the CLI. See the “Installation Procedure” heading here:

I have installed AsteriskNow with Freepbx on my machine, and since I am new to asterisk, I would like to know of any tutorials/admin guide to help me configuring and using. Can anyone help?

Thanks. I got it.
