[SR-Users] Kamailio 3.X.X + BLF configuration trouble

[Vitaliy Aleksandrov]

The NOTIFY without an XML body you received just after a subscription is 
correct.
rfc3265 says:

This SUBSCRIBE request will be confirmed with a final response.
    200-class responses indicate that the subscription has been accepted,
    and that a NOTIFY will be sent immediately.


You can disable such notifies via send_fast_notify presence module 
parameter.

What about further notifications. Kamailio handles subscriptions and 
sends notifications when it receives PUBLISH requests.
Using terms of the rfc3856 kamailio is a "presence server" and you need 
something to act as "Presence User Agent".

You can take a look at pua_dialoginfo module. I haven't used it, but its 
documentation says it can send PUBLISH requests based on active dialogs 
from the "dialog" module.
