Configuring SIP extensions for caller identity and privacy
When a PSTN user originates a call to another PSTN user over a SIP network, the caller identity
presentation can be restricted at the called side or the caller identity can be transparently transmitted to
the called PSTN user by configuring the SIP extension header fields.
The SIP extensions for caller identity and privacy feature can be implemented by adding the
P-Preferred-Identity, P-Asserted-Identity, or Remote-Party-ID header fields.
• When the P-Preferred-Identity or P-Asserted-Identity header field is added, the Privacy header field
will be added. When the Privacy header field is set to none, the caller identity presentation is
allowed. When the Privacy header field is set to id, the caller identity presentation is restricted.
• Remote-Party-ID header field: privacy=off indicates the caller identity presentation and privacy=full
indicates the caller identity screening. The calling information can be transparently transmitted by
adding the Remote-Party-ID header field.
Configuration prerequisites
If a SIP server is used to forward calls, complete the configurations on the SIP server.

P-Preferred-Identity header field or the P-Asserted-Identity header field.
