Hi, I have implemented kamailio with asterisk, I want to enable BLF using
kamailio instead of asterisk. I would appreciate any kind of help, below I'm
pasting my configuration.

*I'm testing with an Aastra phone, when phone sends the subscription
kamailio answers with:*

U ->
SIP/2.0 489 Bad Event.
Via: SIP/2.0/UDP;branch=z9hG4bKa54a155ad67706dca.
From: "1104" <sip:1104 at>;tag=71cf5c9949.
To: <sip:1104 at>;tag=99b712eabe88b2bf7a20409f3dc7ebf1-f71b.
Call-ID: f22823b8b4d58a8e.
Allow-Events: presence.winfo, presence, dialog.
Server: kamailio (3.1.3 (i386/linux)).
Content-Length: 0.

*This is my presence configuration:*

loadmodule "presence.so"
loadmodule "presence_dialoginfo.so"
loadmodule "presence_xml.so"

# ----- presence params -----
modparam("presence", "db_url", DBURL)
modparam("presence", "server_address", "sip:")
modparam("presence_dialoginfo", "force_single_dialog", 1)

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