[Users] DISPATCHER not sending outgoing INVITES 100% of the time

Bogdan,
Thanks for the response. I figured out my issue. Boils down to the fact
that I'm an idiot. If you don't have machines on the network up and
running when dispatcher tries to dispatch a request, subsequent INVITES
will not go out. When building out my setup, I was building each piece
and testing before moving on so I didn't have machines on the IPs
declared in the dispatcher.list yet. Now that I do have machines there,
I get INVITES 100% of the time.
My next step is to set up failure routes for when the forward doesn't
actually happen.
Thanks to all who have assisted.
