Hi Friends,<br><br>i'm using mod_nibblebill for billing on FS, i bundled event processing<br>fucntions when status change,<br>e.g. /* on_routing */ check_billing_before_routing,<br>and * on_hangup */ process_hangup, as below,<br>
however, i found if i make a call containing two-legs e.g. user 1001 call user 1002, then the FS core dump. but if i only make one leg call, e.g. call 888 for IVR, then no problem occure, i found the problem within function "check_billing_before_routing" (because once i comment all of lines within this func, the core did not dump). below is the func "check_billing_before_routing", can anyone help advise what's wrong? how should i correct it, thanks.<br>
