[VoiceOps] Broadworks AS and XSP API questions

Hello all, For those of you who develop against the Broadworks AS and XSP APIs, how do you do testing? We know of the online sandbox instances, but they seem too limited to us, and do include many of the features that we need. Have you licensed a lab instance of Broadworks? If so, how did you go about this? Our reseller doesn't seem to understand the question. Or is there some lab instance or temporary/limited license program that we are unaware of? The same question applies to training systems: we would like to be able to train operators on non-live systems, let them learn to screw it up and fix it, but so far the price seems prohitive to doing this. Thanks! -jjrh
