Hello everyone, Till now we were working with asterisk to handle BLF. But then we decided to move everything to kamailio and hence i started working on BLF with kamailio. I have already configured kamailio for Call handling and presence information.
From different pages on Internet, I have found some information about configuration of kamailio+blf. And i did so, but somehow things are not working as they should.
I have done following changes to kamailio.cfg file
loadmodule "presence.so" loadmodule "presence_xml.so" loadmodule "presence_dialoginfo.so" loadmodule "presence_mwi.so" loadmodule "dialog.so" loadmodule "pua.so" loadmodule "pua_dialoginfo.so"
modparam("presence", "fallback2db", 1) modparam("dialog", "dlg_flag", 4) modparam("dialog", "db_url", "mysql://xxxxxxxxx:xxxxxxxxxxxxxx@localhost/openser") modparam("dialog", "db_mode", 1) modparam("pua", "db_url", "mysql://xxxxxxxxx:xxxxxxxxxxxxxx@localhost/openser")
Now when my phone(yealink VP530), sends subscribe request it looks as below:
SUBSCRIBE sip:1001@172.16.27.66 SIP/2.0 Via: SIP/2.0/UDP 172.16.27.61:5063;branch=z9hG4bK10464096 From: "1000" sip:1000@172.16.27.66;tag=393923564 To: sip:1001@172.16.27.66 Call-ID: 1572901975@172.16.27.61 CSeq: 1 SUBSCRIBE Contact: sip:1000@172.16.27.61:5063 Accept: application/dialog-info+xml Max-Forwards: 70 User-Agent: VP530P 23.70.0.40 Expires: 120 Event: dialog Content-Length: 0
In response to this message, Kamailio returns 202 with following information

During subscribe message asked for XML based reply, yet NOTIFY doesnt send any XML. and hence there is no impact of this message on device. Nothing is changed.Also there's nothing when i call from this device to another, ideally i should get some NOTIFY messages
So, i think i am doing something wrong in Configuration.
Can anyone please help me in it. If you need any other info, i'll provide you.
