The blank settings in ring 1 number are caused by the PHP version not being set to 5.6 which is necessary for Analytic Call Tracking to function correctly.
You can go to your call tracking URL and then append /tester.php after the domain extension. For example, subdomain.rootdomain.com/tester.php
You should be able to adjust the PHP version for your call tracking within cPanel under icons “Select PHP Version” or “MultiPHP Manager”. You only need to set the PHP version for your call tracking install root folder.
If you don’t see the option to set the PHP version to 5.6 within cPanel, alternatively you can try adding a line of code to your .htaccess file. See the code below.
AddHandler application/x-httpd-php56 .php
After you’ve set the PHP version in either cPanel or the htaccess file, verify the version was updated by going back to the /tester.php page. If correct, you should see PHP 5.6.
Once you’ve verified the PHP version is set to 5.6, go back to the Ring 1 number call flow settings and you should be able to see the settings and edit them.
Let me know if you have any more trouble, additional questions or need further assistance.
