CHAPTER60 Configuration Parameters Reference
Mediant 4000 SBC | User's Manual
Parameter Description
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.
'P-Associated-URI
Header'
p-associated-
uri-hdr
[EnablePAssociatedU
RIHeader]
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).
'Source Number
Preference'
configure voip >
sip-definition
settings > src-
nb-preference
[SourceNumberPrefer
ence]
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.
'Reason Header'
configure voip >
sip-definition
settings >
reason-header
Enables the usage of the SIP Reason header.
■ [0] Disable
■ [1] Enable (default)
