Hi,

the actual rewrite is done in the route_func.c:actually_rewrite() function. 
The rewriting URI action is done in the carrier_rewrite_msg() in the same 
file. But why can't your billing server just evaluate the call-id header 
field that is probably present in the SIP message header? This would be much 
more easier then to hack the module code in my opinion.
