Remarks
This value will be used in the outgoing invite request to set the Referred-By header. If this property is not set, Referred-By header will not be added by the platform. If a server platform and application endpoint are configured to use MTLS, Referred-By header will be signed to ensure that it is not altered by anyone else. The platform will not sign the header if added explicitly by the application.
It is important for applications to verify the accuracy of the information given in this property and not simply copy from another source. This may be accomplished by PIN code, logon credentials, or by verifying against a database.
