Marek,
I would try something like the following:

Set that invite to optional=global, and see what happens. I don't know if
you'll be able to get your pause right, but it is worth a try. I would
think that it is certainly possible to do something with variables if you
introduce a few new primitives to SIPp itself (e.g., get the current time
into a variable). You could then sample how long to pause, generate an
absolute time, and then do subtraction between the absolute generated time
and now before you actually do the pause.
