CDR Reports for Outbound Trunk Calls

Hey there,
i want to recognize the bills from our trunk provider.

I want a CDR entry for every outbound call made over a trunk.
It should include the internal accountcode, the CID and the called number, and billsec entry.

At the moment this works only when someone calls the customer from a internal phone, but if the customer gets transfered internal then CDR makes a new entry.

There should be only one entry per external outbound call.
So i can control the cdr report of our trunk provider.
