CCM 7.0 is required to integrate with a 3rd party billing system, what configurations required in this regard on CCM.
What are the pre-requisites for billing system to be compatible with CCM 7.0?
All you need to do is configure the billing server on CUCM
If the billing software is not compatible, the billing system developer would like to know the CDR database schema to customize the billing software. From where these details can be obtained?
As per my understanding from your reffered link the publisher will be CDR Repository Manager & each subscriber in the cluster will be agent, please correct if I am wrong.
