In all reality, Asterisk could be substituted with any other platform.

All the magic happens in the USRP, OpenBTS, and the cellular phones.
Asterisk is merely handling the routing and voice, same as it ever
was.  It is just the top of the stack.

I have two USRPs and a handful of daughter boards, and yes I have two
flex 800s that have been physically altered so they can also be flex
1800s with a simple command line.  These are the boards you want for
GSM (Cellular).

There is also a project to be able to listen into phone calls (thanks
to the French making encryption so weak) besides a ton of other
applications that can be dreamed up.

You can do passive radar, track people that have cell phones powered
on,  RFID (Free tolls anyone?), WiFi, heck, you can even kill people
with certain types of pacemakers.

While OpenBTS is cool and is on topic with Asterisk, read up on
GNURadio and all the projects and applications you can come up with.
It is really cool technology.

Start here http://gnuradio.org/redmine/projects/show/gnuradio but you
can easily find things like this
http://tech.mit.edu/V128/N30/subway/Defcon_Presentation.pdf or come up
with your own with a bit of imagination and skillz.
