\maketitle
\begin{abstract}
This document defines two new SIP header fields for communications
resource priority, namely ``\header{Resource-Priority}'' and
``\header{Accept-Resource-Priority}''.  The \header{Resource-Priority}
header field can influence the behavior of SIP UAs, such as GSTN
gateways, and SIP proxies.  It does not directly influence the forwarding
behavior of IP routers.
