Before RingFree escaped out into the wild a couple of weeks back, we had been going back and forth about how much to charge.

That we need to generate revenues for RF to survive goes without saying. Hardware and bandwidth costs alone are large and continue to grow as we continue to gain new users. To expand to countries outside the US, initially the European countries where the iPhone has been released, and, soon after, others, will make those costs’ skyward climb more pronounced.

When we started to talk amongst ourselves about  the need for revenues, most of us, accustomed to the trialware method of software distribution of many of our favorite computer programs, had settled on the same idea for RingFree.

So, as was reported by various bloggers, RingFree would be available to users free of charge for 30 days, and $30 a year after.

But then something interesting happened. As more and more of you began using RingFree  to make calls on your iPhone that could not be made on any other platform — to Google Talk and Yahoo! Messenger users, for example — we realized we had something much more powerful in RingFree than a $30 program dial out program.

With RingFree, we could help build a communications bridge connecting users of mobile, traditional telephone, and internet calling networks around the world.

And, the best way to build that network is to offer it at no cost its users.

As a web app, RingFree is free and will be free.

We’ll be publicly talking about our plans to generate revenues in these pages shortly (yes, our friend Dameon is on the right track).

But you can now feel free to use RingFree and install your services on it today, and you won’t be asked to pay for it tomorrow.
