Parameter Description
'Source Number

settings > src-nb-
preference
[SourceNumberPreferenc
e]
Defines the SIP header from which 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-Asser-
ted-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:
e. If a P-Preferred-Identity header is present, the number is
obtained from it.
f. 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.
g. If only one P-Asserted-Identity header is present, the call-
ing 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.
