There is no way, with an asterisk box to emulate a particular vendor's switch. You can always change your signalling type and present different signalling protocols (asterisk supports quite a few), but you will never be able to emulate a switch from a different manufacturer, and then of course you have different firmware and model versions to deal with as well.
I can say from experience that connecting two asterisk boxes back to back will get you 80% of the way there, when testing for functionality, but you won't know if you are going to run into a problem until you connect it to the actual switch hardware you plan to connect.
