[Yasin CANER]

     Hello;
     i am trying to understand how is ims_charging working . Kamailio is 
a S-CSCF here. kamailio and call dont have a problem but ro_session.
     i always get ro_session_ontimeout() ERROR. when look diameter trace 
, ims_charging module dont request for 30 more sec for granted and kill 
dialog.
     Thanks for helps.
