"... bandwidth.com uses the FROM field to represent the Caller ID Name
and Number & call rating. If a Remote-Party ID field (RPID) is
included in the SIP INVITE message, the RPID will be used for caller
ID and for call rating. The from field and the RPID must be in a
10-digit format."

OK, so in CUCM I set the Calling Line ID and Name Presentation to "Restricted".

In CUBE, I configured "privacy id" under voice service voip along with
"privacy-policy passthru"

The call leg from CUCM is:

And what was sent to the provider:

Is there some combination of settings that will allow me to send the
"223928" part to the provider so that it shows up in their billing
system, but not send _anything_ to the person being called? I don't
want the called party to see "223928" on their phone, because that's
weird.
