in which documentation says state=4 is terminated? The one for the new 
dialog design? If yes, that is not yet implemented. In current dialog 
module, the state=4 is CONFIRMED.

I checked the logs and the bye is processed by the dialog module, but 
there is no callback to pua_dialoginfo executed. You mention above about 
a patch to pua_dialogninfo, but it is not attached, only test.zip which 
has the debug logs. Can you send the patch or be sure it does not break 
registering the callbacks for pua_dialoginfo?

Cheers,
Daniel
