I added the # to my domain ANI field and did a test. This is the response I got from provider:
Yousent this:
P-Asserted-Identity: "Fidelity" <sip:client-pns@cproxy.sip.voipprovidor.com>P-Charging-Vector:
icid-value=9378916000;icid-generated-at=207.58.218.172;orig-ioi=localhost
That's still not right. But, the From header does reflect the correct data:
From: "Intern Program 2" <sip:9378916000@cproxy.sip.voipprovidor.com;user=phone>;tag=51186
P-Asserted-Identity is preferred, and Remote-Party-Id is the second option. The third option if neither of those work is to not send either and my switch will operate from the From header. But, it is more difficult to signal a blocked call this way.
I suspect there is something else I should be changing to send out a more standard identity.
