Hello, all have a problem with Kamailio presence, I have configured my kamailio.cfg to handle dialog presence and facing issue in case of subs_db_mode = 2 in case of mode 2 facing the following presence issue.

1. after hangup presence is still up
2. sometimes stuck in a ringing state
3. sometimes presence not came..etc

but in the case of subs_db_mode = 3 (DB ONLY) mode presence working fine not facing any issue with this mode.

I noticed that sometimes Kamailio will throw the following message during PUBLISH processing and it will not generate appropriate NOTIFY I also verify inactive watcher subscription is there for that user and also a proper entry in the dialog table.

MSG during PUBLISH processesing and it will not generate appropriate NOTIFY
