[Freeswitch-users] mod_xml_cdr flags b-leg with "a_"

Hi, When a call hangs up normally, like either of the user kept the phone down, then there are no issues. However, when the call is hung up through a transfer, like mod_nibblebill does when "low_balance" or "no_balance" is reached, then the b-leg cdr.xml file gets prefixed with "a_". Is this a desired feature? Or a bug? Regards HASSAN
