Hello,

I am trying to make a Pre-Paid or Advanced billing method for test. But i applied Javascript with FS.

- In my test i am running calls for 3 or 4 hours

- With a billing per minute of 10 US Dollar

Now those calls balance is -200 or -300, how can i tell FS via javascript please kindly stop it because its crossing the limit.

Is there any way to manage it ? 

Thanks & Regards
