[Freeswitch-users] mod_nibblebill and mod_xml_cdr problem

When customer's balance falls below nobal_amt and mod_nibblebill transfers the call to nobal_action (which just does hangup), mod_xml_cdr doesn't send all leg a channel variables to the url (<param name="log-b-leg" value="false"/>). More precisely, it sends only channel variables set by FS, but no variables set by dialplan on leg a. I suspect it sends only leg b variables. Am I right?
