[SR-Users] BLF 'NOTIFY' not working

[Petarr Jones]

Hi

I am using Kamailio 5.2 with the following PRESENCE modules and parameters:

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

modparam("presence", "db_url", DBURL)
modparam("presence_xml", "db_url", DBURL)
modparam("presence_xml", "force_active", 1)
modparam("presence_xml", "disable_bla", 0)
modparam("presence_xml", "integrated_xcap_server", 1)

I have a Yealink T28P phone which has two lines/extensions successfully registered with Kamailio 5.2. When I setup the BLF light to monitor one of the extensions, I get the correct SUBSCRIBE record but the NOTIFY record is sent over and over again until it fails.

When I register the phone with Freeswitch instead and run the same test, the NOTIFY works and I get a much longer NOTIFY message

Should the message coming from Kamailio contain more data or is that not the issue. Should I be including other modules also?

All guidance would be appreciated.
