Hello list,
we're using kamailio presence for BLF functionality, that means lamps on
the phone are green when phone is IDLE, blinking RED when - ringing and
RED when busy.
The problem is - when the phone send SUBSCRIBE first time - presence
answers with empty NOTIFY (with no XML info), and lamps on the phone
(for some extension) are OFF. The laps will became green only after
first call to that extension.
How to make non empty first NOTIFY message ?
My config:
#!ifdef WITH_PRESENCE
# ----- presence params -----
modparam("presence", "db_url", DBURL)
modparam("presence", "subs_db_mode", 2)
modparam("presence", "server_address", SBC_IPADDR)
modparam("presence", "max_expires", 60)
modparam("presence", "db_update_period", 200)
# ----- presence_xml params -----
modparam("presence_xml", "db_url", DBURL)
modparam("presence_xml", "force_active", 1)
modparam("presence_xml", "integrated_xcap_server", 0)
modparam("presence_dialoginfo", "force_single_dialog", 1)
#dialog need as dependence
modparam("dialog", "dlg_flag", 4)
modparam("dialog", "db_mode", 0)
#!endif
