I need an SMS gateway software like [Ozeki NG][1]. I am testing this product right now, but before investing in a commercial product I would like to map the free alternatives.

[Kannel][2] was recommended for me, but it is Linux-based that makes the configuration more difficult.

Do you know any good opensource alternative to Ozeki NG for Windows?

In addition to the basic functionalities, it would be appreciated if the SMS gateway enables email-to-SMS, SMS sending from databases (primarily from MySQL), and some APIs (primarily Java API) would be also useful for me.

Thank you for sharing your ideas in advance!
