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.
Configuration procedure
To configure the SIP extensions for caller identity and privacy feature:
Step
1. Enter system view.
2. Enter voice view.
3. Enter SIP client view.
4. Add the P-Asserted-Identity
header field or the
P-Preferred-Identity header
field.
5. Add the Remote-Party-ID
header field.
NOTE:
The Remote-Party-ID header field can be used together with the P-Preferred-Identity header field or
P-Asserted-Identity header field. If so, the Remote-Party-ID header field takes precedence over the
P-Preferred-Identity header field or the P-Asserted-Identity header field.
