Answer for Gineta, the database user and password that a2billing uses is located in /etc/asterisk/a2billing.conf
If you are trying to modify the username and password, then you can login in Linux Console as root and type the following
Code:
mysql -u root
For most default installation of MySQL, if this command is entered by the root user, no password will be required.
That will give you access to the MySQL client.
Personnaly, I installed PHP MyAdmin. It works pretty well.
Added after 17 minutes: I know what you mean Stavros, but that won't do the trick. Here is how you can reproduce this behavior.
1. Login in the Admin UI
2. Under Ratecard, click on Browse Rates. Make sure that you don't use the ratecard search dropdown list you are told to to so.
3. Unfold the search for and search for a given destination. For instance, Argentina. You will probably see some results
4. Cancel Search. You will notice that all the rates will be shown again (using several pages)
5. Search for a different destination. This time, France. You will see some result again. Which is good. I am assuming that Argentina and France are some of your destinations.
6. Cancel the search again before continuing.
7. Use the Ratecard dropdown list that is standing alon with its own search button. Select a ratecard different than Argentina and France, and click the search button. You will see the rates that belong to that ratecard.
8. Now, try to repeat steps 3 through 5. It will be impossible to see the same result and before unless you logout and login again.
