changing the source code of the rewrite function in the cr module

Any pointers to which specific area of code?

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.
