OK, very good. :)
Let me make sure that this isn't a dialog module bug: You are now calling
dlg_get() followed by dlg_bye() with proper parameters from within the Kamailio
configuration script? if so, you shouldn't need to call dlg_get() in the first
place, at least not if you place dlg_bye() after the call to loose_route().
Contrary, using certain dialog features (including dlg_bye()) from reply routes
isn't completely possible yet which could explain your findings.
Cheers,
