I got this idea of using E51 to call anywhere for free. I was thinking about an E51 with one of these unlimited SIM card, constantly plugged in to the charger, which would work as kind of a gateway, that could be used by more people (not in the same time though).
So, do you have any idea how to do this? How to control this phone remotely?
I've been thinking about DTMF, like I call the phone -> the phone calls back -> i enter a phone number -> the phone dials this phone number and connects me and the phone number I entered into a conference .
Do you think there is any way to do it? Another slution could be an E51, constantly connected to a PC, so that the PC could do all this stuff.
Or is there any other device, that could do the trick?
