Wikki has the most data on Teleport Communications Group which is what nomorobo uses.

The number you set into your phone system is 202 813 1600

I tried calling it and it is busy

Better Business Bureau has no rating for this company

The obama administration has made me very paranoid

I should add;

I use Comcast for voice and internet (the only one available to me)

The phone number I cited may be only for Comcast users

You are correct about Comcast:

Not sure why you’re paranoid. You say Comcast is your phone service and internet provider. Obviously they already have your phone number and email address.

Not familiar with that, what is the source for nomorobo using TCG?

Nomorobo goes by the corporate name Telephone Science Corporation and states it's privacy policy here.
