Parameter Description
[SourceNumberPreference]
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.

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).

[ZeroSDPHandling]

IP address of 0.0.0.0 in the SDP's Connection Information field (i.e.,
