Hi Lebing,

In JSIP 1.2 you can create a server Tx for any request. What the null 
ServerTransaction in your RequestEvent  indicates is that the original 
ServerTransaction was not created by the UAS in the first place ( please 
verify if this is the case). If you had actually created the initial 
ServerTx and you saw a Null coming into the RequestEvent, I'd like to 
explore this further. I'll try a test or two to see if things are 
working ( let me know before I dig though ).

Regards

Ranga
