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.
Specifies the name of SIP header to transparently pass.
The flexible header transparency profile supported in earlier release, where transparency for a random header is achieved by adding its name to the profile. The functionality was limited to initial INVITE request, REGISTER request, and mid-dialog requests in an INVITE initiated dialog (excluding a mid-dialog SUBSCRIBE as it is not supported). Selective unknown headers can be passed transparently in REGISTER, initial INVITE, and in mid-dialog requests in an INVITE initiated dialog. Header transparency was not supported for out-of-dialog messages in earlier SBC release.
The SBC supports the following out-of-dialog functionality:
- To enable transparency for "all" the headers.
- To selectively ignore transparency of headers (useful with "all" transparency).
- To exclude the methods for which transparency of headers is not needed.
