[OpenSIPS-Devel] dialog module: dialog not cleaned up when BYE is sent

Wed Mar 4 11:53:32 CET 2009

I forgot to answer one of your questions -Also, is the dialog still 
present in the DB?-

I don't save the dialog state to a DB, I could turn this on if that 
would help. If needed, I guess I should use the REALTIME db_mode and a 
db_update_period of 1 second or something?
