tom,
i cannot understand, how anything can work if there is no to tag in

Juha,
I agree... And the funny thing is that the To tag is in the 401, but
somehow it's not recognized by sipctrl. See the SEMS logging (level 3)
below. Notice the To tag in the 401 and the Debug message about the
missing To tag...
