Technical Summary

   This document specifies the use of SCTP (RFC 2960) as the
   transport for SIP (RFC 3261).  SCTP was designed for the
   transport of SS7 signaling messages, and a number of the features
   it supports might be useful in SIP implementations.

   Note that this is not a proposal that SCTP be adopted as the primary
   or preferred transport for SIP, rather it just describes how to
   add SCTP and SCTP/TLS to SIP's available transports.

Working Group Summary

 The working group had consensus to advance the draft to Proposed
 Standard.

Protocol Quality

 An implementation of SIP over SCTP in Linux has been
 developed.  

 Review of this specification for the IESG was by Allison Mankin.
