draft-lior-radius-prepaid-extensions-22.txt quota reached

RouterOS General
1

Hi all.
I would like to implement Appendix A.1 page 69 in the draft-lior-radius-prepaid-extensions-22.txt using "quota reached " instead of “threshold reached”
http://tools.ietf.org/html/draft-lior-radius-prepaid-extensions-22#appendix-A

For Duration rating, My RADIUS server provider request me to use DurationQuota instead of VolumeQuota.

does anybody can support me to achieve this?

Regards!
