IMPORTANT

Ribbon recommends using the Transparency Profile to configure transparency on the SBC Core for new deployments, as well as applying additional transparency configurations to existing deployments. Do not use IP Signaling Profile flags in these scenarios because the flags will be retired in upcoming releases.

Refer to the SBC SIP Transparency Implementation Guide for additional information.

This section lists the CLI to configure various SIP egress IP attributes involved in sending a call in the forward direction to the peer.

Parameter

Description

useIpSignalingPeerDomainInRequestUri 

Enable this flag to use IP Signaling Peer Domain in Request URI.

  • disable (default)

  • enable

useSipDomainInPAIHeader

Enable this flag to set the value of the host port of the PAI URI equivalent to the value of the SIP domain name configured on the ingress trunk group of the Policy Exchange Server (PSX).

  • disable (default)

  • enable

 useSipDomainNameInFromField

By default, the SBC uses its IP address as the host-port of the FROM URI in the outgoing INVITE message. Enable flag to use the originating gateway information returned in the policy response as the host-port of the FROM URI in the outgoing INVITE message.  

  • disable (default)
  • enable

When useSipDomainNameInFromField is enabled, the following flags are available:

  • preserveIngressFromDomainName – If a SIP domain is configured for the ingress trunk group and this flag is enabled, the default gateway associated with that SIP domain will be the originating gateway. Otherwise, the originating gateway will be the default gateway associated with the SIP domain associated with the Softswitch entity.
    • disable (default)

    • enable

  • useLowerCaseDomainNames – Set flag to allow lower case domain name.
    • disable (default)

    • enable

NOTE: The above two flags only apply when a Domain Name is configured for this zone (refer to Zone - CLI).

 useSipDomainNameInRequestUri

Use this flag to indicate how to treat SIP Domain name in outgoing SIP INVITE.

  • disable – The SBC includes the IP address in the host-port portion of the Request-URI in outgoing SIP INVITE messages.
  • enable – The SBC includes the trunk group domain associated with egress trunk group as destination domain name in outgoing SIP INVITE messages.

When useSipDomainNameInRequestUri is enabled, the following parameters are available:

  • preserveIngressRUriDomainName – Preserve Ingress R-URI Domain Name Flag. When enabled, the ERE/SBC uses domain name received in the Request-URI as destination domain name in outgoing SIP INVITE messages.

map3xxContactUrlToRouteHeader

When map3xxContactUrlToRouteHeader  flag is enabled,  SBX adds 3XX contact header as second route header in the outgoing INVITE message.

This flag is enabled on a IBCF TG because when a call is routed by ECSCF to IBCF, the 3xx contact URI need to be added as second route header for subsequent routing to IP-PSAP.

  • disable (default)
  • enable
map181Or182MessageTo183
Enable flag to allow SBC to map 181 or 182 response messages to 183. When disabled, the SBC handles 1xx response messages normally.

  • transparencyForDestinationTrunkGroupParameter – When enabled, if ERE receives both tgrp parameter and trunk-context in an ingress INVITE Request-URI, ERE as proxy transparently passes the tgrp parameter and trunk-context in the egress INVITE Request-URI. Values selected for the "Destination Trunk Group Option" are ignored.
    • disable (default)
    • enable
generateCallIdUsing

Use this parameter to control ingress and egress Call-ID behavior.

  • doNotUseIngressCallId – Generates egress Call-ID independent of ingress Call-ID.
  • useIngressCallIdByAddingStaticString – Generates egress Call-ID using ingress Call-ID and a static string (egressCallIdStaticString) configured in the SIP trunk group.
    Egress Call-ID is the aggregate of ingress Call-ID and static string.
  • useIngressCallIdByPrepending – Generates egress Call-ID using ingress Call-ID and locally generated string. Egress Call-ID is the aggregate of ingress Call-ID and locally generated string.
includeChargeInformation

Select the includePChargeInfo option to map charge information in a call setup message (i.e., the charge number parameter of an IAM) to egress P-Charge-Info header in INVITE message. If the ERE returns billing information in a policy response, the SBC ensures that the egress P-Charge-Info header in INVITE message is populated with the indicated data. If the SBC receives a SIP INVITE message for a call destined to the PSTN, the SBC populates the charge number parameter of the outgoing IAM based on the egress P-Charge-Info header in INVITE message.

  • includeNone (default)
  • includePChargeInfo
originatingTrunkGroupOptions

Use this parameter to specify originating trunk group options.

  • includeNone (default) – Do not include any trunk group information.
  • includeOtg – Include the originating trunk group parameter in SIP headers sent over the associated trunk group.
  • includeTgrpWithDomainName – Include the originating trunk group, and include the trunk context as domain name.
  • includeTgrpWithIpAddress – Include the originating trunk group, and include the trunk context as IP address
sessionExpiresRefresher

Controls whether the refresher parameter is sent in the Session-Expires header and is enabled when the Customized Session Timer Behavior flag is selected. Options include:

  • notSend (default) – The Session-Expires refresher parameter is not sent in the initial outgoing INVITE message, re-INVITE message, and UPDATE message.
  • Uac – When selected, the parameter refresher uac (User-Agent Client) is sent in the Session-Expires header.
  • Uas – When selected, the parameter refresher uas (User-Agent Server) is sent in the Session-Expires header.

sipToHeaderMapping

This parameter indicates which number is mapped and returned in the outgoing SIP To header. Options include:

  • calledNumber – The TO header is mapped using the called number.
  • gapDialedNumber – The TO header is mapped using the Generic Address Parameter from mime, if applicable.
  • none (default) – The TO header user part is mapped from the Original Called Number, if present. Otherwise, it is mapped from the Called Number. The Original Called Number may be taken from the Diversion or the History-Info header, if present, in a SIP Invite.
  • originalCalledNumberOcn – The TO header is mapped using the redirecting original Called number OCN parameter. This is filled from the SIP Invite using the Diversion or the History-Info header, if present.
