I've worked as a teletraffic engineer for 35 years, originally at Bell Labs.

Are you talking about the situation where the Poisson process depends on a state that is itself a Markov Process - ala Meier-Hellstern and Lucatoni and Neuts? Or perhaps a batch arrival model? Are you having trouble simulating this, or fitting the parameters? And are you sure simulation is the way to go - Neut's Matrix-Geometric methods makes many of these problems tractable analytically, whereas reliable simulation estimates of rare events is a tricky thing.
