Hello,

I'm trying to configure Kamailio 5.1 like "presence" server. Pretty much with default settings of kamailio:

# ----- presence params -----
modparam("presence", "db_url", DBURL)
;modparam("presence", "server_address", "sip:10.0.6.226:5060" )
modparam("presence", "send_fast_notify", 0)
modparam("presence", "db_update_period", 20)
modparam("presence", "clean_period", 40)
modparam("presence", "subs_db_mode", 2)
modparam("presence", "fetch_rows", 1000)

# ----- presence_xml params -----
modparam("presence_xml", "db_url", DBURL)
modparam("presence_xml", "force_active", 1)

# ----- presence_dialoginfo params -----
modparam("presence_dialoginfo", "force_single_dialog", 0)

# ----- pua params -----
modparam("pua", "db_url", DBURL)
modparam("pua", "db_mode", 2)
modparam("pua", "update_period", 60)
modparam("pua", "dlginfo_increase_version", 0)
modparam("pua", "reginfo_increase_version", 0)
modparam("pua", "check_remote_contact", 1)
modparam("pua", "fetch_rows", 1000)

# ----- pua_dialoginfo params -----
modparam("pua_dialoginfo", "include_callid", 1)
modparam("pua_dialoginfo", "send_publish_flag", FLT_DLGINFO)
modparam("pua_dialoginfo", "caller_confirmed", 0)
modparam("pua_dialoginfo", "include_tags", 1)
modparam("pua_dialoginfo", "override_lifetime", 124)

# ----- dialog params -----
modparam("dialog", "db_url", DBURL)
modparam("dialog", "enable_stats", 1)
modparam("dialog", "db_mode", 1)
modparam("dialog", "dlg_flag", FLT_DLG)

And when UDP transport is using, everything works perfect. But when TCP is using (only "listen: tcp:IP:5060" is set) NOTIFY is not send. When "listen: tcp:IP:5060" and "listen: udp:IP:5060" I receive NOTIFY but through UDP. SIP trace is bellow:
