You can add this AVPs with whatever ID but string type. Also take care 
to correlate the IDs in radius client and server. Also be careful not to 
overlap with any already existing ID.

I'm not sure how cdrtool works or if yon need to do some extra 
configuration in opensips to make it work. The Accouting and Radius part 
in opensips allows you to configure extra fields to be sent to the 
radius server, but such customization depends on the requirements of the 
radius server application....
