Hello<br>
I would like to use nibblebilling for fraud prevention on
international and premium numbers ( national or emergency calls
should never be blocked and should still working even if the billing
database is unavailable )<br>
<br>
Unfortunately that never hangup my calls using standard dial plan<br>

<br>
<b>Using b-leg only</b><br>
Alternatively i tried an alternative dialplan ( Even if i don't
relay understand what is the meaning of b-leg billing )<br>
<br>
<tt><action application="bridge"
data="{enable_heartbeat_events=5,nibble_rate=0.1,nibble_account=${accountcode},originate_timeout=90}sofia/gateway/gw_idt/33$1"
/></tt><tt> </tt><br>
<br>
The result is better because the pending call is hanged up when the
balance reach 0.<br>
<br>
<tt>2016-04-10 12:39:59.012462 [CRIT] mod_nibblebill.c:607 Balance
of -0.003237 fell below allowed amount of 0.000000! (Account </tt><tt><a href="http://company.voip.domain.com" target="_blank">company.voip.domain.com</a></tt><tt>)</tt><br>
<br>
But if i make a new call ( when my balance is negative ) , the
caller party is immediately hanged but this did not cancel
immediately the bridge: The called party ring and can stay bridged
for 61 seconds after answer.<br>
