I had this same problem but eventually overcame it. I modified the docs at
http://wiki.freeswitch.org/wiki/Amazon_ec2 accordingly. I think the problem I had was the internal vs. external IP address, as you've alluded to at the bottom of your message. In addition to the changes you've made, I also modified sip_profiles/internal.xml - see the docs. -larry On Wed, May 6, 2009 at 9:20 PM, Dave Grootwassink <stackofstuff...@gmail.com > wrote: > Hello all, > > > > Help a n00b out.
