Thank you for your response Klaus. I added the Event header and still got a bad 
request responce from
windows messenger. The last two packets look like this:

10.41.2.41 = Linphone
10.41.2.52 = Messenger

U 10.41.2.41:5060 -> 10.41.2.52:8435

exit


I observed this process betwen two messengers and I noticed that they dont use 
event header. They add an XML message to the
body of a packet and thats how they achieve event notification. Here is how it 
looks NOTIFY from one messenger to another:

10.41.2.56     1. messenger
10.41.2.197    2. messenger

U 10.41.2.56:1657 -> 10.41.1.197:13712

Naturaly, :) I tried to emulate this and added a simmilar body to my NOTIFY 
packet on linphone.
Of course nothing happened .. bad request again.
Any ideas?
