Please someone blow the lid off the telco fraud world already. The reason companies such as telesign exist is because telcos are allowing fraudsters and scammers to run amok using their infrastructure and in lots of cases directly benefiting from their activities or even participating themselves. The whole telephone system is broken and the ones running the show are not showing any intent to fix it.
