Hi there,

I have a Freeswitch install I'm resurrecting from a while back that once worked, but seems to not be anymore.  What I wanted to do, to start, is make sure that the machine was working properly.

I fired it up and registered two clients on softphone apps, extensions 1002 and 1003; when I tried to get them to call one another, I got back a 404 error and a "No route, aborting"/NO_ROUTE_DESTINATION message in the logs.  Does anyone have any clues?  I am pretty much a complete newbie at troubleshooting these sorts of things.  Thanks in advance for any help...

My debug log is at the bottom, but first here is what I see when I check sofia status profile external; note that the clients appear and are registered (see below):
