I looked into this a couple of weeks back (check the list archives). 
There is preliminary GR-303 support in Asterisk CVS, but it appears to 
be for Asterisk to talk to GR-303 access concentrators, not for Asterisk 
to act as one.

I too am interested in this, as I suspect we could get better rates and 
more flexible service from our CLEC if we used GR-303 instead of PRI. 
However, from my reading of the GR-303 spec, it appears that GR-303 
assumes a very tight "coupling" between the switch and the access 
concentrator, to the point of having the access concentrator 
configuration and reconfiguration actually handled _through_ the switch. 
If that's the case, I don't know if it will ever make sense for Asterisk 
to use GR-303 to communicate with a class 5 switch; more likely we'll 
want Asterisk to gain SS7 support and that will take care of it (along 
with many other benefits).
