Category: modules Group: ver devel >Status: Closed >Resolution: Accepted Priority: 5 Private: No Submitted By: Alex Balashov - Evariste System (abalashov) >Assigned to: Daniel-Constantin Mierla (miconda) Summary: is_known_dlg() exported function from dialog. Initial Comment: Provides a new exported function from the dialog module - is_known_dlg(). This can be used from script to determine if the message being processed is part of an existing dialog tracked by the dialog module, rrespective of the use of profiles. Because the dialog module is plugged into the RR / TMCB event loop it is aware of all dialogs regardless of whether profiles are used. Thus, this function will return positively if any message is part of a known existing dialog. I have included documentation changes in doc/dialog_admin.xml. This patch is against the kamailio-1.4.1-notls release tarball, not trunk. But it should apply to devel version regardless. ---------------------------------------------------------------------- >Comment By: Daniel-Constantin Mierla (miconda) Date: 2010-09-24 14:03 Message: Applied on git master. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=743022&aid=2270836&group_…
