P-Sig-Info is a  Sonus proprietary header used to transport various signaling parameters like SGD (Super Generic Digits), UUI (User-to-User Information), Contractor Number, etc. in SIP-I to SIP interworking cases.

The interworking of SGD parameter and SIP P-Sig-Info header is not applicable when the SBC is configured for ERE mode.

The CLI syntax to map various signaling parameters to the P-Sig-Info header is shown below:

  • Map the UUI parameter into the SIP P-Sig-Info header.

    % set profiles signaling ipSignalingProfile <SIP profile name> commonIpAttributes flags mapUuiInPSigInfoHeade enable

  • Map the Contractor Number parameter into the outgoing SIP P-Sig-Info header.

    % set profiles signaling ipSignalingProfile <SIP profile name> egressIpAttributes flags mapContractorNumberInPSigInfoHeader enable

  • Map Called Party Category parameter to outgoing SIP P-Sig-Info header.

    % set profiles signaling ipSignalingProfile <SIP profile name> ingressIpAttributes flags mapCalledPartyCategoryInPSigInfoHeader enable
