Dear Sir, I have successfully installed freeSWITCH and it works fine in passthrough mode. I installed nibblebill and it deduct money from the accounts database and it works fine. but I have two problems. 1. Calls can be initiated even though there is a minus value in accounts database 2. Calls doesn't hangup when it goes to minus values. Any answers are greatly appreciated. This is my dialplan: <action application="nibblebill" data="flush"/> <extension name="hangup"> <condition field="destination_number" expression="^(hangup)$"> <action application="playback" data="no_more_funds.wav"/> <action application="hangup"/> </condition> </extension> <extension name="Omega_Out"> <condition field="caller_id_number" expression="^(\d{4})$"/> <condition field="destination_number" expression="^(\d{11})$"> <action application="set" data="nibble_rate=0.0448"/> <action application="set" data="nibble_account=${accountcode}"/> <action application="set" data="bypass_media=true"/> <action application="bridge" data="{absolute_codec_string=g729}sofia/gateway/OMEGA/5544$1"/> </condition> </extension> This is the configuration file; <configuration name="nibblebill.conf" description="Nibble Billing"> <settings> <!-- See http://wiki.freeswitch.org/index.php?title=Mod_nibblebill for help with these options --> <!-- Information for connecting to your database --> <!-- The database table where your CASH column is located --> <!-- The column name where we store the value of the account --> <!-- The column name for the unique ID identifying the account --> <!-- Default heartbeat interval.
