I believe the concern about listing a company's upstream carriers is overstated. There simply aren’t as many carriers as there used to be, and businesses have consolidated who they terminate calls to due to S/S. This simply isn’t a commonly exploited attack vector. Even if someone tried, it would be noticed and addressed within a few hours. We work with a core set of about 10 carriers that legitimate providers and our competitors and other players in the market typically use, and this information isn’t top secret. I understand you've seen this happen, but of all the risks we face as providers, I'd rank this one at the bottom of the list.
