If you go this route, make sure you absolutely know how to, and that you absolutely lock this down. SIP toll fraud is still a problem and if it happens to you, it can get destructively expensive.

Common sense obviously applies. With a cell phone, don't call back to unknown numbers ringing once or twice ("wangiri"). With a SIP trunk, don't allow remote anonymous access.

Yeah I suppose it's really easy to call this common-sense, it probably should be common-sense.

Yet at the same time, if it were common-sense in practice, I probably wouldn't have a job.
