If the device receives a SIP 503 response to an INVITE, it also
marks that the proxy is out of service for the defined "Retry-After"
period.
Determines the device usage of the P-Associated-URI header. This
header can be received in 200 OK responses to REGISTER
requests. When enabled, the first URI in the P-Associated-URI
header is used in subsequent requests as the From/P-Asserted-
Identity headers value.
■ [0] Disable (default)
■ [1] Enable
Note: P-Associated-URIs in registration responses is handled only if
the device is registered per endpoint (using the User Information
file).
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-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:
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-Asser-
ted-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 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)
