I suppose you have already installed AsteriskNow 1.5 and you would have found that reports don't work out of the box. It always says "No data". Apparently the system is not logging the calls and we have to enable this with some additional configuration. Below are the steps for that:
Login to your asterisk server as root and type yum install asterisk-addons-mysql. Select Y when it asks for installation. Once this is done you can see that all calls that go through your server are tracked and reported. But the Admin web interface displays the following error: reporting an error "Asterisk Manager Connection Failure" (If you don't get that error then below step is not required).
To fix the error go to web interface, Choose Administrators under Basic section. Select admin user and give the password (same as what you have in amportal.conf and manager.conf files). Apply changes. That's it.
After that the system will starts tracking all the calls getting through it.
