Hi,<div><br></div><div>When a call hangs up normally, like either of the user kept the phone down, then there are no issues.</div><div><br></div><div>However, when the call is hung up through a transfer, like mod_nibblebill does when &quot;low_balance&quot; or &quot;no_balance&quot; is reached, then the b-leg cdr.xml file gets prefixed with &quot;a_&quot;.</div>

<div><br></div><div>Is this a desired feature? Or a bug?</div><div><br></div><div>Regards</div><div>HASSAN</div><div><br></div>
