But you probably need the gateway into the PSTN to use SS7 and IMT trunks; and that probably means a CLEC license in the US, or similar elsewhere. That presumably means more substantial civil and criminal penalties for spoofing with criminal intent, not to mention the potential loss of the operating license for doing so. So although it is certainly doable, it'll be expensive and likely beyond the means of small-time players. In short, if you have direct SS7 access, there isn't much you cannot do to screw over other providers and their customers. Hense all of the rules and regs for getting such access. -JimC -- James H.
