[SR-Users] ims_charging module

[Shane Harrison]

Hi all ims'ers

I have modified the ims_charging module to cope with the CCA return code of "CREDIT CONTROL NOT APPLICABLE".  This means the call is not a chargeable call and the charging module now returns a unique return code for this.

Currently there are two scenarios handled:
1) CCA grants the credit required for the call --> route the INVITE and then automatically new CCR requests are made for further credit as the call progresses
2) CCA doesn't grant the credit  ---> send an error response back to INVITE originator - I assume this will clear all dialogs and no further credit requests are made. 

The question I have, is how do I cope with this unique return code so that I can continue to route the call but not make any more CCR requests to the credit control server?  As I am not sure how the ims_charging module continues to generate CCR requests, it is difficult for me to understand how to essentially clear the whole CCR session without clearing the call.

Kind regards
Shane
