Carrier Grade Linux discussion

Hello,

To somewhat formally introduce myself, my name is Matthew Fredrickson 
and I work for Digium, the company that is behind the Asterisk project. 
  I have done development at nearly every level of that project from the 
VoIP side of the world to the traditional telephony side (PRI, SS7, 
etc).  I also have done work at the kernel level doing zaptel and 
device driver development related to telephony platforms.

As I was searching through the archives, I noticed that there has been 
practically no activity for years.  Is there a particular reason for 
this, and if not, is there something useful that we as a special 
interest group do for furthering linux as a carrier grade telephony 
platform?
