Hi Jeff.  What exactly do you mean by the 'inbound piece'?  I've spent
quite a lot of time with the folks at TILTX understanding the framework;
but I am not exactly sure what you mean by the 'inbound piece.

Greg/Doug, like many folks here, we use LCR.  So, the terminating carrier
is not necessarily the one that issued us the telephone numbers.  So, they
will not sign it or simply cannot sign it.  Remember that a very limited
number of companies can actually sign the calls; the rest have to buy it
from these 'Service Providers'.

And there is another situation - the company you purchase your numbers from
and the company you place your calls through may be different and both may
not be able to sign your calls.  Again, a very limited number of service
providers that can actually sign your calls.  So what do you do in that
scenario?  You have to find a Service Provider that can:

1.  Verify you own that telephone number(s).
2.  Sign your calls.
3.  Provide you with the technical means to do so.

So, that's that...  I hope this makes sense.
