I am trying to implement BLF functionality as described in http://kb.asipto.com/kamailio:presence:k43-blf.

I am using the same conf with the one in the tutorial except that i am using postgres database instead of mysql.

The problem is BLF is not working with this config (presence server and proxy server are in the same kamailio with same IP). But when I separate presence server from proxy server (2 different kamilio boxes with different IPs) BLF working perfect. 

i can see PUBLISH & NOTIFY messages in the tcpdump output with the working configuration.

But i can not see any PUBLISH messages in the tcpdump output with the original config (one with presence and proxy servers are same).

My question

in the normal working environment (when BLF working perfectly);

should i see PUBLISH and NOTIFY messages in the tcpdump output when the presence and proxy servers are the same? 

thanks
