[SR-Users] Storing in-progress dialogs in database

Hi all, I'm testing with the new dlg_db_load_callid function to replicate dialogs to another (standby) kamailio instance on failover. This works fine for calls that are connected. But i'm missing the dialogs in "ringing" state. Looks like dialogs are written to database by the dialog module when we receive the 200OK/ACK for the invite transaction. The result is that the call gets connected on the other kamailio instance but without a dialog. Is it possible to store the early_dialogs that are in rining state in the database? If that is not the case can i still create a dialog when i only receive the 200OK/ACK to the INVITE transaction (INVITE was processed by another instance) since TM is not aware of the INVITE transaction? I also tried to reject the 200OK to the INVITE in the on reply route, but running into the same issue that TM does not know the INVITE transaction. Thanks, Jan
