The Session Initiation Protocol (SIP) "Caller Preferences" extension,
defined in RFC 3840, provides a mechanism that allows a SIP message
to convey information relating to the originator's features and
capabilities. This document defines a new SIP header field, Feature-
Caps, that can be used by entities to indicate support of features
and capabilities, in case they cannot use the Contact header field
for that purpose.
