Configure SIP Headers for SIPREC Metadata
To get more detailed information about a recorded session, you can add more SIP headers within the SIPREC metadata by way of the Extension-Headers option. The default behavior stores only the Request-URI and realm-id.
You must configure the Extension-Headers option at the global level under spl-config because the session-agent, realm-config, and sip-interface configurations do not recognize the option. The first time you configure one or more extension headers, you need only to save and activate the configuration for the system to recognize the extension headers. When you modify the existing SPL extension header list you need to save and activate the configuration, and reboot the system for the changes to take effect. Real Time Configuration (RTC) does not apply to extension header options.
