Yeah, I'm getting your point. 

So now, here are my loaded modules.

#!ifdef WITH_PRESENCE

loadmodule "presence.so"

loadmodule "presence_xml.so"

loadmodule "presence_dialoginfo.so"

loadmodule "pua.so"

loadmodule "pua_dialoginfo.so"

loadmodule "pua_usrloc.so"

#!endif

And of course:

loadmodule "dialog.so"

Attached are the relevant sip traces.

You didn't receive any NOTIFY requests because you didn't have a PUA client. rfc3903 describes what a PUA client is.

To make BLF work you can try to use the next modules:
1. dialog - to enable dialog awareness
2. pua + pua_dialoginfo - to enable a PUA client based on active dialogs information provided by the "dialog" module
3. presence + presence_dialoginfo - to handle subscriptions and send notifications to phones

Hi list,

I've been trying to make my Yealink phone to give BLF indications but I haven't been able to achieve this successfully yet so I need some expert advise here.

My Yealink phone, as soon as it registers to Asterisk, gives me BLF lights. The same phone registering to Kamailio sends SUBSCRIBE and nothing happens.

The Presence Handling is enabled in configurations and yet no dialog-info+xml NOTIFY is received.

Please help.

Best Regards,

Sammy Go.
