CONFIGURATION ELEMENTS N-Z SESSION-AGENT
sustain-rate-window—Enter the sustained window period in seconds used to
measure the sustained rate. The term “window” refers to the period of time over
which the sustained rate is computed.
Default 0
Values Min: 0 / Max: 2
32
-1
req-uri-carrier-mode—Select how a carrier determined by the local policy
element should be added to the outgoing message
Default None
Values • None—Carrier information will not be added to the outgoing message
• uri-param—Adds a parameter to the Request-URI (e.g., cic-XXX)
• prefix—Adds the carrier code as a prefix to the telephone number in
the Request-URI (in the same manner as is done in the PSTN)
proxy-mode—Select how SIP proxy forwards requests coming from the session
agent. If this parameter is empty, its value is set to the value of the proxy-mode
parameter in the sip-interface element by default. If the proxy-mode field in the
element is also empty, the default is proxy.
Values • proxy—If the Net-Net SBC is an SR, the system will proxy the request
coming from the session agent and maintain the session and dialog
state. If the Net-Net SBC is a Net-Net SBC, system will behave as a
B2BUA when forwarding the request.
• redirect—System will send a SIP 3xx reDIRECT response with contacts
(found in the local-policy) to the previous hop
• record-route—The Net-Net SBC forwards requests with a record-
route
redirect-action—Select the action the SIP proxy takes when it receives a Redirect
(3xx) response from the session agent. If the response comes from a session agent
and this field is empty, the redirect action value will be recurse.
Values • proxy—SIP proxy passes the response back to the previous hop. The
response will be sent based on the proxy-mode of the original request.
• recurse—SIP proxy sends the original request to the list of contacts in
the Contact header of the response, serially (in the order in which the
contacts are listed in the response)
loose-routing—Enable or disable loose routing
Default enabled
Values enabled | disabled
send-media-session—Enable or disable the inclusion of a media session
description in the INVITE sent by the Net-Net SBC. The only instance in which this
field should be set to disabled is for a session agent that always redirects requests,
meaning that it returns an error or 3xx response instead of forwarding an INVITE
message. Setting this field to disabled prevents the Net-Net SBC from establishing
flows for that INVITE message until it recurses the 3xx response.
Default enabled
Values enabled | disabled
