Level 3 is a big wholesale route for a lot of smaller IXC carriers and
VoIP providers, so when they fix it, you'll probably see immense
improvement.

I'm really hoping Level3 is having a routing issue with our code. Some
tried a call on level3 to us which failed. Odd things is that Level3 is
directly connected to the Tandem we subtend. I wouldn't think Level3
would send it off their network???

What's worse really is not that you have to look at ILEC tandems out of
area - they don't perform any route filtering, if the originating caller
is calling out of area, it gets sent to their PIC/LPIC LD carrier.
So what you really need is every IXC in the country to make sure they
have a route to you either directly, through whatever tandem homing
arrangements you have, or via another IXC (really common especially in
rural areas to see a Level 3/Global Crossing hand off to
Qwest/AT&T/Verizon for the final termination.).

So, at the very least, I need to start looking at each of the ILEC's
tandems in a specific LATA?

Take Kidd's call from Verizon in Colorado. If there isn't our
exchange in their local switch, do they forward the call on to
another switch in hopes that it will know where to send it? Similar
to a default gateway in IP world?
It would get kicked up to an ILEC tandem inside that LATA. There is
really no default gateway beyond that; at that point, you've already
exited into what the IP world would call "default route-free" or "Tier
1" routing space.
