How to restart Asterisk server
From Kolmisoft Wiki
You should never restart it. That would be perfect.
But there are situations when you need to do it no matter what.
If you restart/shutdown your Asterisk server when there are active calls going:
- Users will be disconnected and will not feel very happy about your service;
- You will lose money on the active calls, because provider will charge you for these calls but you will not be able to charge your users because calls will not be in database.
 How to do it the right way?
