This is also a fun attack. Find a provider that does this. Request to port a target number (a bank or an escort service or whatever). Port will stall for a bit, in the mean time, the service provider activates your number internally, so their own dialers route to their &quot;version&quot; of the number.<p>Now you get all the calls from that provider to that number. Forward them to the actual destination (using an unrelated provider) and no one will notice for a while. Except, you get all the calls and media.
