Yes, it's possible.

Good move if you're prepared to sacrifice call quality, however not all 
devices support GSM....

I guess what you're actually asking is how to do it?

Get the book -

   http://www.asteriskdocs.org/modules/tinycontent/index.php?id=11

it's free, or buy a paper copy from Amazon.

But to start, you need to look up the sip.conf and iax.conf files. Put 
this in them at the appropriate point

disallow=all
allow=gsm
