If you know the rate and the balance for the call, you may calculate the maximum time for the call as max_time = balance/rate. Then you may schedule a hangup for that call max_time in the future, something like this:<div><br>
</div><div>sched_hangup +&quot; + max_time + &quot; &quot;+ call_uuid +&quot; &#39;ALLOTED_TIMEOUT&#39;<br><div><br></div><div>That way the balance shouldn&#39;t go below 0, since you are hanging up the call before it does, with hangup cause ALLOTED_TIMEOUT.</div>
