Info

The Transparency Profile is the recommended method of configuring transparency on the SBC Core for new deployments as well as when applying additional transparency configurations to existing deployments. Do not use IPSP 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 CLI commands to configure various SIP egress IP attributes involved in sending a call in the forward direction to the peer.

BCI

Command Syntax

% set profiles signaling ipSignalingProfile <SIP profile name> egressIpAttributes bci 
	bciInterworkEncountered <disable | enable> 
	bciIsdnAddess <disable | enable> 

Command Parameters

Table : BCI Parameters

 

ParameterDescription

bci

Use this object to configure Backward Call Indicator (BCI) for Egress IP attributes.

  • bciInterworkEncountered – Enable flag to indicate that ISUP is interworking with a network which is not capable of providing as many services as ISUP does. ISUP networks will therefore not employ certain features they otherwise normally would, including potentially the use of ISDN cause codes in failure conditions .
    • disable (default)
    • enable
  • bciIsdnAddess – Enable flag to enable ISDN Address in the BCI parameter of backward SS7 messages (e.g. ACM or ANM).
    • disable (default)
    • enable

 

Domain Name

Use this object to specify use of domain names. 

Command Syntax

% set profiles signaling ipSignalingProfile <SIP profile name> egressIpAttributes domainName 
	useIpSignalingPeerDomainInRequestUri <disable | enable> 
	useSipDomainNameInFromField <disable | enable> 
		preserveIngressFromDomainName <disable | enable> 
		useLowerCaseDomainNames <disable | enable> 
	useSipDomainNameInRequestUri <disable | enable> 
		preserveIngressRUriDomainName <disable | enable> 
		useLowerCaseDomainNames <disable | enable>

	useZoneLevelDomainNameInPathHdr <disable | enable>

Command Parameters

Table : Domain Name Parameters

 

Parameter

Description

useIpSignalingPeerDomainInRequestUri 

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

  • disable (default)
  • enable

 useSipDomainNameInFromField

By default, 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 parameters 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

The above two flags only apply when a domainName is configured for this zone (see Zone - CLI page).


 useSipDomainNameInRequestUri

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

  • disable – SBC includes the IP address in the host-port portion of the Request-URI in outgoing SIP INVITE messages.
  • enable –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. Normally, outgoing SIP INVITE messages contain the trunk group domain assigned to egress trunk group.
    • disable (default)
    • enable
  • useLowerCaseDomainNames – Set flag to allow lower case domain names.
    • disable (default)
    • enable

useZoneLevelDomainNameInContact

Enable flag to use Zone level domain name in the Contact header.

  • disable (default) 
  • enable
useZoneLevelDomainNameInPathHdr

Enable flag to send the Domain Name configured at the Zone level in the Path Header of the outgoing REGISTER message.

  • disable (default) 
  • enable

  • disable (default)
  • enable
bgcfTargetSchemeTransparencyEnable flag to preserve the scheme used by the SIP INVITE Request-URI when the INVITE is routed by the SBC, acting as a BGCF supporting Tel-URL. When disabled, the SBC changes the scheme used by the Request-URI parameter to SIP in the egress INVITE message.
  • disable (default)
  • enable
convertInactiveToSendrecvEnable flag to control the a-line in the SDP of an egress SIP INVITE message by converting a=inactive to a=sendrecv. When disabled, the SBC continues to use a=inactive, when appropriate, in the egress INVITE message.
  • disable (default)
  • enable
disable2806Compliance

If enabled, the 2806 Compliance Code is disabled and no phone context or user=phone parameters are signaled in egress messages.

  • disable (default)
  • enable
disableOptionalRegisterParametersEnable flag to prevent SBCfrom sending the DTG (Destination Trunk Group) parameter in the Contact header of egress REGISTER messages.
  • disable (default)
  • enable
ignoreSdpAfterOfferAnswerCompletedEnable flag to allow the SBC to ignore the new SDP at the egress leg in subsequent 1xx-rel or final 200 OK messages after the Offer Answer for the initial Invite dialog was completed by an earlier 1xx-rel (and does not trigger a new offer or answer).
  • disable (default)
  • enable
includeEnumParametersUse this flag to specify how to handle ENUM parameters in outgoing INVITE.
  • disabled (default) – SBC drops ENUM parameters received from ENUM server.
  • enabled – SBC sends ENUM parameters in the outgoing INVITE
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
map181Or182MessageTo183Enable flag to allow SBCto map 181 or 182 response messages to 183. When disabled, the SBC handles 1xx response messages normally.
  • disable (default)
  • enable
mapContractorNumberInPSigInfoHeaderEnable flag to map the Contractor Number parameter into the outgoing SIP P-Sig-Info header. The P-Sig-Info header is a customer-specific SIP header used to convey ISUP information in SIP messages.
  • disable (default)
  • enable 
qosBasedRouting

Enable flag to allow QoS-based routing.

  • disable (default)
  • enable
sameCallIdForRequiredAuthorization

Enable this flag to support sending an INVITE with credentials on receiving a 401 (Unauthorized) or 407 (Proxy Authentication Required) response to initial INVITE with the same call ID as in the original INVITE.

  • disable (default)
  • enable

Note

To view and configure this flag, you must first enable both 'authCodeHeaders' transparency flag and 'statusCode4xx6xx' relay flag. See Transparency Flags - CLI and Relay Flags - CLI for additional details.


suppressUnregister

Enable flag to prevent SBC from sending an unregister message (Register=0) to the registrar upon expiration of a SIP UA registration. When disabled, the SBC generates unregister messages on the egress leg if the UA does not refresh the registration on time.

  • disable (default)
  • enable 

transitPAIFromUnregisteredPeer

Enable flag to transparently pass the received PAI to the INVITE if the default PUI procedure cannot add a PAI header.

  • disable (default)
  • enable 

To use this flag, you must enable the enableDefaultPUIProcedures flag and disable the 'privacy transparency' flag (See Privacy section below).


ttcIsupMappingWhen enabled, and when the IP protocol type of the IP signaling profile entry is SIP or SIP-I, the application that receives the SBC policy response (which can be either the SIP signaling gateway application on the SBC or the SIP core proxy on the SBC) applies the mapping necessary for TTC-ISUP signaling.
  • disable (default)
  • enable 
 useCalledPartyInRequestUri When enabled, the SBC copies the username selected for the "To" header to the Request URI instead of the registered username. When disabled, the SBC includes the registered username in the Request URI. This flag is used when interoperating with IP-PBXs that require the real end station number in the Request URI in order to do proper routing of calls terminating on them.
  • disable (default)
  • enable
useColonInSdpMediaTypeParameter

When enabled, a colon (:) is used as the separator between the SDP Media Type parameter key and value. When disabled, an equal sign (=) is used as the separator between the SDP Media Type parameter key and value.

  • disable (default)

  • 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.
