server to answer 3g phone, what software?
i'm looking for a way for my linuxbox to automatically pick up a cell phone (3g nokia connected via usb). once the call has been set up, i'd like some way for the caller to be able to leave a video message in any format or just as stdin (so i can pipe it to ffmpeg). i have no idea of what to look for... a ppp app maybe? any hints of what to look for are deeply appreciated.
(this stuff just got to exist as net providers do this already...)
