Finarea/Betamax is a VOIP service provider offering cheap calling rates by various services, e.g. sipdiscount.com, freecall.com, voipbuster.com etc...
The Finarea Midlet emulates the actions necessary to initiate a call using the web interface of these services by sending the same HTTP requests as the browser does if done manually. This way you can have ultra-cheap (or even free) calls from your mobile! Here is what happens:
1. start the Finarea Midlet
2. choose the contact you want to call
3. select one of the services you configured, e.g. freecall.com
4. Finarea Midlet opens a HTTP connection (additional costs may apply depending on your data plan!), logs in your freecall.com account and initiates the call
5. a few seconds later you will receive the callback. Once you accept the call you will be connected to the other party.
