
[1] Enable
Note: P-Associated-URIs in registration responses is handled only if the
device is registered per endpoint (using the User Information file).
Determines from which SIP header the source (calling) number is
obtained in incoming INVITE messages.

If not configured or if any string other than "From" or "Pai2" is
configured, the calling number is obtained from a specific header using
the following logic:
a. P-Preferred-Identity header.
b. If the above header is not present, then the first P-Asserted-
Identity header is used.
c. If the above header is not present, then the Remote-Party-ID
header is used.
d. If the above header is not present, then the From header is used.

"From" = The calling number is obtained from the From header.

"Pai2" = The calling number is obtained using the following logic:
a. If a P-Preferred-Identity header is present, the number is obtained
from it.
b. If no P-Preferred-Identity header is present and two P-Asserted-
Identity headers are present, the number is obtained from the
second P-Asserted-Identity header.
c. If only one P-Asserted-Identity header is present, the calling
number is obtained from it.
Note:

The "From" and "Pai2" values are not case-sensitive.

Once a URL is selected, all the calling party parameters are set from
this header. If P-Asserted-Identity is selected and the Privacy header is
set to 'id', the calling number is assumed restricted.
Enables the usage of the SIP Reason header.

[0] Disable

[1] Enable (default)
Defines a name for the device (e.g., device123.com). This name is used
as the host part of the SIP URI in the From header. If not specified, the
device's IP address is used instead (default).
Note:

Ensure that the parameter value is the one with which the Proxy has
been configured with to identify the device.

The parameter can also be configured for an IP Group (in the IP
Groups table).
Determines the device's response to an incoming SDP that includes an IP
address of 0.0.0.0 in the SDP's Connection Information field (i.e., "c=IN
IP4 0.0.0.0").

[0] = (Default) Sets the IP address of the outgoing SDP's c= field to
0.0.0.0.

[1] = Sets the IP address of the outgoing SDP c= field to the IP
address of the device. If the incoming SDP doesn't contain the
"a=inactive" line, the returned SDP contains the "a=recvonly" line.
