Yes. A complete one-to-one mapping between states will almost always be impossible, though. This is because you will seldom have two call models with the same number of states and transitions (if you did, why map them at all?) The utility of the resulting mapping will depend on how granular the states are between the call models. For instance, a call model with less number of states and low cardinality transitions can still be mapped to a call model with a high number of states and many transitions through state splitting. However, introducing an artificial state in this fashion is problematic at best. It raises many additional questions: how does the new state behave in principle with the rest of the states of the call model in which it was introduced? The call model may not be amenable to such an artificial introduction of a new state. How does the designer of the new state decide on the amount of functionality that should be in it, in relation to the state it was carved out from? How easy will it be to realize such a system in working software? SIP has been mapped to a PSTN call model quite effectively for certain services (see RFC3976.) Hope that helps. - vijay -- Vijay K.
