I've cranked up this AMI. 

My biggest problem is that no audio arrives at the switch from the client.  As far as I can tell.  But I had this problem before, when I was using a more generic AMI and building Freeswitch on top of it. 

Another issue is that this AMI runs on a large EC2 instance, which costs four times as much as a small instance.  While it's great to have a ready-made image for bigger iron like this, but for now, I just want to pay the minimum.
