7.14.7.3 Caller ID on the IP Side

7.14.7.3.1 Overview
Caller ID is provided by the From header containing the caller's name and "number", for
example:
From: "David" <SIP:101@10.33.2.2>;tag=35dfsgasd45dg
If Caller ID is restricted (received from Tel or configured in the gateway), the From header
is set to:
From: "anonymous" <anonymous@anonymous.invalid>; tag=35dfsgasd45dg
The P-asserted (or P-preferred) headers are used to present the originating party's caller
ID even when the caller ID is restricted. These headers are used together with the Privacy
header.
If Caller ID is restricted:
•
The From header is set to "anonymous" <anonymous@anonymous.invalid>
•
The 'Privacy: id' header is included
•
The P-Asserted-Identity (or P-preferred-Identity) header shows the caller ID
If Caller ID is allowed:
•
The From header shows the caller ID
•
The 'Privacy: none' header is included
•
The P-Asserted-Identity (or P-preferred-Identity) header shows the caller ID
In addition, the caller ID (and presentation) can be displayed in the Calling Remote-Party-
ID header.
