Do you have record_route() in your code? Where is it relative to the
ims_charging function?

This is non-blocking and one of the parameters in the call is the route block to be called ( e.g. CHARGING_CCR_REPLY ) when the response to the charging request is obtained.  Looking at the code, the  Ro_CCR() function does a t_suspend() and then the ims_charging module does a  t_continue() when the response is received.  Then the specified routing block is called and processing of the INVITE continues.
