[SR-Users] How to do accounting for Kamailio-generated BYEs?

Hi I've got a mediaproxy that detects no media, and sends dlg_end_dlg to Kamailio via mi_datagram socket. Then Kamailio sends BYE to both calling parties. It all works fine. But my question is, how to do accounting for these Kamailio-generated BYEs? They don't appear in the acc table. I'm using Kamailio 3.1.5. Thank you very much!
