Re: [SR-Users] Dialog module not decrementing profile size

Hello Daniel, Yes, dlg_manage() is being called in the BYE, yet it sometimes still occurs that dialogs aren't being cleared. It is critical for us the dialogs are being cleared as we have an application which heavily relies on this.

Most of the time this works as it should, but sometimes the 'slots' available for a profile aren't cleared even though a dialog has finished. This seems to happen when an high amount of regular traffic is hitting kamailio. Has anyone else experienced this? Are there perhaps any other ways to control the slots available for certain incoming SIP traffic? Below parts of my configuration file. Perhaps I'm doing something wrong which causes this to happen. In my route[WITHINDLG] -> loose_route -> is_method("BYE") I'm not calling dlg_manage(), could this be the problem? is the dlg_manage() executed or not for BYE? You say no above, but the example has it. Because you have dlg_match_mode=2, you must call dlg_manage() for BYE explicitly.
