[asterisk-users] Connect intercom to Asterisk?

[Gilles]

Hello

I just read this article about a kid in England who built a box with a
3G SIM card:

When someone rings your intercom, the box will call your cellphone so
you can answer just like you were home.

I don't know anything about electronics and would like to have
something similar by connecting the intercom end in my appartment to a
PC running Asterisk that will dial a phone number through SIP.

Does someone know if something like that is available ready to use
(Arduino, etc.)?

Thank you.
