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

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

but in 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 following message during PUBLISH processesing and it will not generate appropriate NOTIFY i also verify in active watcher subscription is thare for that user and also proper entry in dialog table.

MSG during PUBLISH processesing and it will not generate appropriate NOTIFY
