This specification creates a new IANA registry, "SIP Feature Cap
Registry", which is used to register indicators, "SIP feature caps",
used by SIP entities to indicate support of features and
capabilities, in cases where the Contact header field contains a URI
that does not represent the SIP entity that wants to indicate support
of its features and capabilities.
This specification also defines a new SIP header field, Feature-Caps,
that can be used by SIP entities to convey information about
supported features and capabilities, using SIP feature caps.
