[cisco-voip] Robo Call DoS

[Anthony Holloway]

Technically or legally?

How does one stop a DoS attack on a network?  Or on anything for that
matter?  Say you were attending a protest, and someone is blowing an air
horn in your ear <https://youtu.be/cvAMkDGKelQ?t=80>?  What can you do?

Technically, you could front end the whole thing with a captcha style gate,
so you could ask to push a single button, button combination, or solve a
simple addition problem resulting in two digits.  granted, just like on the
web, a captcha is burdensome to the user, but generally, it's preferable
over the site being down, or disrupted.

CUC and UCCX both could handle this task, though it would be easier in UCCX.
