Select the Signaling Profile to configure from the drop-down list. The Egress Flags window is displayed.


Use the following table when configuring the options and then click Save.


Egress - Egress Flags Parameters:

Parameter DefaultDescription
Add Prefix011For International CallsDisableEnable this flag to add the prefix 011 for international calls.
Add Prefix1For Inter Lata CallsDisableEnable this flag to add the prefix "1" for Inter LATA calls.
Add Prefix1For Intra Lata CallsDisableEnable this flag to add the prefix "1" for Intra LATA calls.
Annex ESupportDisableEnable this flag to support Annex E.
Apply Switch Type Cpc ProfileDisableEnable this flag to use the "CPC/OLI Parameter Mapping" feature on the associated Trunk Group(s).
Call Back When Free SupportDisableEnable this flag to use the "Call Back When Free" feature on the associated Trunk Group(s). The PSX includes the "Call Back When Free" attribute in the route structure when the Trunk Group is included in the route list.
Called Number7DigitsDisableEnable this flag to send the 7-digit called number in the outgoing signaling protocol.
Calling Number7DigitsDisableEnable this flag to send the 7-digit calling number in the outgoing signaling protocol.
Change Bearer Cap From3_1KHz To SpeechDisableEnable this flag to reset the 3.1 kHz bearer capability received from the ingress to speech for this outgoing Trunk Group.
Convert Numbers To E164FormatDisableEnable this flag to convert numbers to E.164 format.
Cpc MappingDisableEnable this flag to allow CPC mapping on the associated Trunk Group(s).
Dialed Number As Called NumberDisableEnable this flag for the PSX to populate the called number (associated with a returned route) with the dialed number.
Disable Charging Authority For Chosen CarrierDisable

When this option is enabled, the SBC does not delete the ISUP parameters from the ACM and CPG messages.

This allows the CHG message to transit when it is acting as the chosen carrier.

Discard Calling And Contract NumbersDisable

When this option is enabled, the SBC does not include the calling and contractor numbers in egress signaling when:

  • the calling number NOA is network-specific and the first digit of the calling number is not "0," or
  • the calling number screening is set to "User Provided," "Verified," and "Failed."
Discard GAPAddl Clg If Same As Clg Number And Ingress SIPDisableWhen this option is enabled, for SIP-to-ISUP calls, the SBC does not include the GAP additional calling number in the egress signaling if it is the same as the original calling number.
Discard Tns And Trunkgroup Owning Carrier MatchDisableEnable this flag to discard the TNS parameter when it matches the Owning Carrier assigned to the egress trunk group.
Dont Strip Clg Number For Restricted PresentationDisableWhen this option is enabled, the PSX does not strip (delete) the digits of the calling number for restricted presentation.
Forced Override Olip ValueDisableWhen this option is enabled and a value other than none in the Forced OLIP Value field exists in the ingress portion of the trunk group for this Signaling Profile, the value in that field is copied to the OLI parameter on the egress trunk and sent in the PSX policy response.
Generate Fe ParamDisableEnable this flag to generate the FE parameter.
Oli MappingDisableEnable this flag to support OLI Parameter mapping on the associated trunk group(s).
Overwrite Charge Information If Chosen IXCDisableEnable this flag for the SBC to modify parameters related to a charge indication if the value of the Carrier Type parameter determined by the PSX is "Chosen IXC."
Perform Called Party Member CheckDisableEnable this flag for the PSX to check the called party member status in the subscriber table for the JTI prefix.
Propagate Charge MessageDisableEnable this flag for the PSX to propagate the CRG messages received on the associated egress trunk group from succeeding exchanges to the originating exchange for billing purposes. 
Propagate Gd ParamDisableEnable this flag to propagate the Generic Digits parameter (switch ID/trunk group ID) in the forward direction in the egress IAM.
Propagate Ingress Channel InfoDisableEnable this flag to propagate the ingress PSTN channel information in the INVITE header sent by an SBC to a SIP Server (via the "chan" parameter in the From: field).
Reorder Trunk Based On ISUP PreferenceDisableEnable this flag for the PSX to order route lists appropriately for calls over ISUP trunks that terminate to a protocol converter for R2 signaling.
Replace Prefix0With Plus81For Translation Source NumberDisableWhen this option is enabled and the Translation Source Number has a prefix 0, the PSX replaces the prefix 0 with +81 for SIP signaling. The Translation Source Number without the +81 is recorded in the CDRs.
Reroute On Signaling CongestionDisableEnable this flag to reroute calls on the associated trunk group to an alternate route.
Reset Olip For Toll Free CallsEnableEnable this flag for the SBC to reset the OLIP for toll-free calls to the pay phone code.
Restore Calling Number If Derived From Billing NumberDisableEnable this flag to send the calling number that came in the policy request in the policy response.
Restore Calling Number If Derived From Redirecting NumberDisableWhen this option is enabled, the SBC does not delete the ISUP parameters from the ACM and CPG messages, allowing the CHG message to transit when acting as the chosen carrier.
Restore Calling Number If Derived From Trunk GrpDisableWhen this option is enabled and if the PSX derives the calling number from the default calling number associated with the ingress Trunk Group during call processing, the original calling number is restored before the call is sent in the egress Trunk Group.
Restore Fci International BitDisableEnable this flag for the PSX to copy the incoming FCI A-bit to the outgoing FCI A-bit.
Send Billing Number As Clg NumberDisableEnable this flag for the PSX to populate the contents of the billing number over to the calling party parameter.
Send Billing Number As Clg Number If Clg Number Not PresentDisableWhen this option is enabled and if the calling number doesn't exist or the calling number presentation is set to Restricted, the PSX populates the calling number field in the policy response with the billing number.
Send Calling Number When Not Derived From InputDisableWhen this option is enabled and if the calling number doesn't exist or the calling number presentation is set to Restricted, the PSX populates the calling number field in the policy response with the billing number.
Send Contract Number If Allowed By Ingress SIPDisableWhen this option is enabled ingress SIP signaling, the Contractor Number, if it exists, is sent in the egress signaling.
Send Toll Free Number In Gap ParamDisableEnable this flag to send the toll-free number in the Generic Address Parameter (GAP).
Send Toll Free Number In Ocn ParamEnableEnable this flag to send the toll-free number in the Original Called Number (OCN) parameter.
Strip Rep Area Code DigitsEnableEnable this flag to remove the RAC digits from the called party number.
Transit All Redirection Number NOADisableEnable this flag for the PSX to inform the SBC to forward the R-REL transparently to the previous switch, regardless of the NOA.
Undo LnpDisableEnable this flag for the SBC to cancel LNP on the associated Trunk Group(s).
Use Output ANIFor CDNISDisableEnable this flag to use the Automatic Number Identification (ANI) in the egress signaling for the ANI provisioned in the Custom DNIS DM rule on the associated egress Trunk Group.
