It is important to know what kinds of people you want to call. Ibrahim and his friends, were calling random numbers in the US. Calling Democratic party members would have been more effective, though of course they did not have access to this information. Still, if you know the person that you want to call - the office of a political leader, for example - then international online phone-banking is a great (and so far under-used) tactic.
