sip-interface

The sip-interface element allows you to configure a SIP interface for your Oracle Communications Session Border Controller.

Parameters

state
Enable or disable the SIP interface
  • Default: enabled
  • Values: enabled | disabled

Note:

Oracle does not recommend disabling and re-enabling a sip-interface operating with TCP ports. Depending on conditions and circumstances, you may not be able to re-enable this sip-interface without rebooting the system. If you need to disable, then re-enable a sip-interface, ensure that:
  • There are no ESTABLISHED in-bound sockets
  • The access-control-trust-level of the realm must not be configured to low or medium
realm-id
Enter the name of the realm to which the SIP interface applies
description
Provide a brief description of the sip-interface configuration element
sip-ports
Access the sip-ports subelement

initial-inv-trans-expire
Transaction expiration time <TIMER_B> for initial INVITE.
  • Default: 0
  • Values: 0 - 2147473
invite-expire
Set the INVITE transaction expiration timer in seconds
  • Default: 0
  • Values: Min: 0 | Max: 2147473
max-redirect-contacts
Enter the maximum number of contact and route attempts in case of a redirect
  • Default: 0
  • Values: Min: 0 | Max: 10

    • proxy—Forward all SIP requests to other session agents
    • redirect—Send a SIP 3xx redirect response with contacts (found in the local policy) to the previous hop
    • record-route—Forward requests with Record-Route (for stateless and transaction and operation modes only)
redirect-action
Set handling of Redirect (3xx) response messages from a session agent.
  • Default: Empty
  • Values:
    • Proxy—Send the response back to the previous hop
    • Recurse—Recurse on the contacts in the response

      Note:

      The nat-traversal parameter can establish an important media handling behavior. If you set nat-traversal on a sip-interface to always, this setting supersedes any multi-media configuration that would otherwise release the media. Instead, the SBC recognizes when a flow's leg is behind a NAT during the signaling, and ignores any configuration that would release the media. The SBC then sets up the end to end media flow in MBCD and performs its HNT function for that flow.

    • insert—Inserts the P-Charging-Function-Address header in an incoming SIP message that does not contain the P-Charging-Function-Address header. If the incoming message contains the P-Charging-Function-Address header, the Oracle Communications Session Border Controller will prepend its configured values to the header.
    • insert-reg-cache—To be configured on the SIP interface facing the UE, configures the Oracle Communications Session Border Controller to replace the PCFA with the most recently cached values rather than the ccf-address you set to be static in your configuration. The cached values come from one of the following that the Oracle Communications Session Border Controller has received most recently: request, response, registration, or local configuration.
    • delete-and-respond—To be configured on the SIP interface facing the S-CPCF, configures the Oracle Communications Session Border Controller to strip out the latest cached PCFA.
    • conditional-insert—Inserts the P-Charging-Function-Address header in an incoming SIP message that does not contain the P-Charging-Vector header. If the incoming message contains the P-Charging-Function-Address header, the Oracle Communications Session Border Controller passes the P-Charging-Function-Address header untouched as the message is forwarded, extracting RADIUS information.

    Note:

    Note that the default setting for the charging-function-address-mode is pass for new SIP interface configurations. If you are upgrading and there are pre-existing SIP interfaces in your (upgraded) configuration, the default becomes none.
