Supported Privacy Types
SIP peers can be configured with the following privacy types:
- P_ASSERTED (default option)
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. Privacy types are used as follows:
- If P_ASSERTED is the selected privacy type, Bandwidth will pull the TN from the ' P-Asserted-Identify' field only.
- If there is no TN information populated in 'P-Asserted-Identify', the value in the 'Remote-Party-ID' field will then be used.
- If no TN information is populated in 'Remote-Party-ID', the TN in the ‘From’ header will be used.
- If REMOTE_PARTY_ID is the privacy type, the value in the 'Remote-Party-ID' header will then be used as the ANI.
- If the Remote-Party-ID header is empty, the TN populated in the ‘From’ header will be used.
- If P_CHARGE_INFO is the privacy type, the value in the 'P-Charge-Info' header will be used as the ANI.
- If there is no TN information populated in 'P-Charge-Info', the value in the 'Remote-Party-ID' header will then be used.
- If no TN information is populated in 'Remote-Party-ID', the TN populated in the 'P-Asserted-Identify' header will be used.
- Finally, if there is no value in 'P-Asserted-Identify', the TN in the ‘From’ header is 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 ECC (Emergency Call Center) for processing, unless you have requested that unprovisioned calls be denied.
Populating values in all privacy headers (P-Asserted-Identity, Remote-Party-ID, and P-Charge-Info) is not recommended.
