Caller ID Parameters
Parameter Description
Web: Asserted Identity
Mode
EMS: Asserted ID Mode
[AssertedIdMode]
Determines whether the SIP header P-Asserted-Identity or P-
Preferred-Identity is used in the generated SIP INVITE, 200 OK, or
UPDATE request for Caller ID (or privacy). These headers are used to
present the originating party's Caller ID. The Caller ID is composed of
a Calling Number and a Calling Name (optional).
 [0] Disabled = (Default) P-Asserted-Identity nor P-Preferred-Identity
headers are not added.
 [1] Add P-Asserted-Identity
 [2] Add P-Preferred-Identity
The header used also depends on the calling Privacy (allowed or
restricted). These headers are used together with the Privacy header.
If Caller ID is restricted (i.e., P-Asserted-Identity is not sent), the
Privacy header includes the value 'id' ('Privacy: id'). Otherwise, for
allowed Caller ID, 'Privacy: none' is used. If Caller ID is restricted
(received from PSTN / Tel or configured in the device), the From
header is set to <anonymous@anonymous.invalid>.
The 200 OK response can contain the connected party CallerID -
Connected Number and Connected Name. For example, if the call is
answered by the device, the 200 OK response includes the P-
Asserted-Identity with Caller ID. The device interworks (in some ISDN
variants), the Connected Party number and name from Q.931 Connect
message to SIP 200 OK with the P-Asserted-Identity header. In the
opposite direction, if the ISDN device receives a 200 OK with P-
Asserted-Identity header, it interworks it to the Connected party
