Thank you for building this. It helped us verify that we are correctly
passing the Identity headers.

I've found that no one is universally passing the headers end to end to all
the test numbers. Some of our vendors will make it all the way to most but
not all. I also think that some of the inbound validation is failing
because of how the DID is routed to the end device. If a trunk is set to
deliver e164 with a + in the From but the Identity header doesn't contain
that, the validation match fails.

I've tested the ZipDX numbers, Sansay, and Voxbeam numbers from full LCR
and "OnNet" trunks via ANI, Bandwidth, Comcast, Intrado, Peerless, Sinch,
and Level3.

The closest to perfect is ANI's Toll Free passes validation to all 3 of
ZipDX's TF DIDs. Bandwidth OnNet passes validation to all the numbers that
are reachable via that route.
