Use the Header window to specify the filtering settings for individual types of SIP headers within a selected SIP Filter profile. Refer to Signaling - SIP Filter Profile for more information. By default the setting for all headers is Disabled, which means they are subject to parsing by the SBC when received in an ingress message.

ParameterDescription
Header

The name of the header under a SIP Filter Profile. For a list of permissible headers, see Permissible SIP Headers.

To enable filtering for a header, configure the setting to Enabled.

  • Disabled (default)
  • Enabled

If a header is known and the filter setting for the header is set to Disabled (default), the header is parsed by the SBC. In case of any parsing error, the SBC terminates a call. However, if the filter setting for a known header is set to Enabled, the SBC does not parses the header, even if parsing for the header is supported by the SBC. Additionally, all known filtered headers and unknown headers can be transparently relayed without parsing, if the unknown header transparency is Enabled in IP signaling profile..
