I have a php page that queries for active calls every 5 seconds. I want to get incoming calls and updating my database with existing calls, whether it was answered/missed, how long the call was ect. It works great for 10 queries then will not allow further queries until after a time has passed. I am assuming there is a limit to the number of queries allowed. I am in sandbox mode. Will this limit change when the App goes into production mode? Is there a way to automatically open a url when a call comes in on rings end. Any help would be appreciated.
