1. When tariffs are posted, and agreed, the parties are required in law to abide by them. There is no provision for simply not paying the bill. The venue for having a discussion about whether the bill or the rules are appropriate is at the FCC, but incumbents can't simply opt out of delivering traffic they had previously agreed to deliver.
2. The volume of traffic going to rurals is tiny. In order to build a substantial business from it, a company like ours would have to be doing hundreds of millions of minutes per month of business. The real money for us is in the paid services, and we use the free services as a marketing tool.
3. We market our paid services to our free customers with clear information on the point at which the volume of calling makes it cost effective to use our paid services — see http://www.calliflower.com/node/234 for details.

As for why you or anyone else should foot bills… well, you aren't. Unless you're calling our service, you're not paying for it. Nor, for that matter, is your telephone company, or the US taxpayer. When the telephone company customer pays the company to connect a call, the tariff regime says that the company is required to share the money they collect from the customer with the carriers who receive the calls. If you don't want to pay for services hosted in rural telco's, then simply don't call them. You have that option.

Answer this question, beyond simply taking advantage of current regulations what has your company invested in the rural carriers which should entitle payment of termination fees? Why should I or anyone else foot the bill for calls delivered to your rural carrier?

To me you are not more than a simple scam artist.
