Hi

I have this idea that I'm not sure it it's possible ...

I want to call my home # where I have a linux box with a modem.
The linux box detects that I've called and wait for 30s then calls me back
(here the gray part begins )
my n810 is connected to my phone trough BT and some how when my house is calling my cell, n810 detects that it's an dial in call and takes control and negotiate with my linux box and in the end I have free internet on my n810 ... because I have unlimited incomings calls on my cellphone plan.

Any one tried something similar?
The first part I know how to do it since I did it before but not sure if the second part it's possible

Thanks,
Alin
