This document extends SIP with two header fields and associated
option tags that can be used in INVITE requests to convey the
requester's preference for user-interface handling related to
answering of that request. The first header, "Answer-Mode",
expresses a preference as to whether the target node's user interface
waits for user input before accepting the request or, instead,
accepts the request without waiting on user input. The second
header, "Priv-Answer-Mode", is similar to the first, except that it
requests administrative-level access and has consequent additional
authentication and authorization requirements. These behaviors have
applicability to applications such as push-to-talk and to diagnostics
like loop-back. Usage of each header field in a response to indicate
how the request was handled is also defined. [STANDARDS TRACK]
