Supported privacy types for 911 services

SIP peers can be configured with the following privacy types:

• P_ASSERTED (default option)
• REMOTE_PARTY_ID
• P_CHARGE_INFO

Bandwidth will pull the address information associated with the TN populated in either P-Asserted-Identity, Remote-Party-ID, or P-Charge-Info headers, based on what is selected in the peer configuration.

P_ASSERTED

1. If P_ASSERTED is the selected privacy type, Bandwidth will pull the TN from the P-Asserted-Identity field only.
2. If there's no TN information populated in P-Asserted-Identity, the value in the Remote-Party-ID field will then be used.
3. If no TN information is populated in Remote-Party-ID, the TN in the From header will be used.

REMOTE_PARTY_ID

1. If REMOTE_PARTY_ID is the privacy type, the value in the Remote-Party-ID header will then be used as the ANI.
2. If the Remote-Party-ID header is empty, the TN populated in the From header will be used.

P_CHARGE_INFO

1. If P_CHARGE_INFO is the privacy type, the value in the P-Charge-Info header will be used as the ANI.
2. If there's no TN information populated in P-Charge-Info, the value in the Remote-Party-ID header will then be used.
3. If no TN information is populated in Remote-Party-ID, the TN populated in the P-Asserted-Identity header will be used.
4. Finally, if there's no value in P-Asserted-Identity, the TN in the From header will be used.

If no information is populated in any of the above fields, the call will receive a generic ANI and will be passed to the Emergency Call Center (ECC) for processing, unless you've requested that unprovisioned calls be denied.

Note: We don't recommend populating values in all privacy headers (P-Asserted-Identity, Remote-Party-ID, and P-Charge-Info).
