Two calls today, second one at 7:20 pm. This time I was home and heard one ring, then No mo blocked it.
On a different note, apparently this other website is poaching comments from 800notes.com without crediting the source: http://www.called2us.com/phone_number/4243545329
They copied and pasted my above post, and changed my screen name to "anon". Hmmmm.... not cool.
