The Session Initiation Protocol (SIP) supports the capability to
provide a reference to the alternative ringback tone (RBT) for
caller, or ring tone (RT) for callee using the Alert-Info header.
However, the reference addresses only the network resources with
specific rendering properties. There is currently no support for
predefined standard identifiers for ringback tones or semantic
indications without tied rendering. To overcome this limitations and
support new applications a family of the URNs is defined in this
specification.
