[OpenSER-Users] Dialog module... again! - sr-users

10 Jun 2008

Hello all,

     Got a question for those well versed on the Dialog Module. I have it
working great against a db,  but it seems to me that -although there's
nothing on the module's documentations to indicate it- Dialogs are inserted
on the table once the initial transaction is finished, i.e. 200 OK.

Here's my script...
