Abstract:
This specification defines a new SIP header field, Feature-Caps, to
convey feature capability indicators, which are used by SIP entities
not represented by the URI of the Contact header field to indicate
support of features and capabilities, where media feature tags cannot
be used to indicate the support.
This specification also defines feature capability indicators, and
creates a new IANA registry, "Proxy-Feature Feature Capability
Indicator Trees", for registering feature capability indicators.
