Also, we implemented immediate answer and voice menu option, it says "Welcome, press ... to reach ...!" and circles. So me (as the telco operator) receive the money for call termination, and real customer do not get a spam call. Looks like captcha in the Internet!
Ha! As discussed earlier in this thread, I have implemented the same thing. But I am just a single end-user, not a telco. It's so incredibly effective that I have wondered often if any telcos had actually implemented such a thing for their customers, even as an option, or even a paid service. I have also wondered though how ineffective it might become with wide deployment effectively upping the ante in the arms race. The captcha would have to get more difficult. "Enter the result of 1+3 to reach...". I wonder how many real people that would trip up though with "WTF?". Lots would probably try to press 1 and then 3, etc. Cheers, b.
