It's about accounting but requires some extra. I must generate a 
unique id and attach it in a specific header. Hint: RFC 3544,
P-Charging-Vector.

Thanks - anyhow, I'm afraid that this does not solve my
problem. 
As stated already before: Inserting the call-id into an
AVP and writing it to the SIP header is no problem. What 
makes the topic difficult is to store the content in a
call-specific (and not contact-specific) way.
