<div dir="ltr">Another idea can be have the customers to opt-in for auto-refill if they want to use multiple call feature. Usually this does not have be a high number, just autorefill the account if the balance goes down $1. <br>

Thanks guys for inputs...not allowing multiple call is not an option -<br>
essentional thats the problem we try to solve :)<br>
<br>
Since we have our own CDR module, we can avoid external process. What<br>
are the evens to listen for?<br>
<br>
Other ideas will also be appreciated.<br>
