The IESG has received a request from the Sip Traversal Required for
Applications to Work WG (straw) to consider the following document:
- 'A Taxonomy of Session Initiation Protocol (SIP) Back-to-Back User
   Agents'
  <draft-ietf-straw-b2bua-taxonomy-02.txt> as Informational RFC

The IESG plans to make a decision in the next few weeks, and solicits
final comments on this action. Please send substantive comments to the
ietf@ietf.org mailing lists by 2013-07-01. Exceptionally, comments may be

Abstract


   In many SIP deployments, SIP entities exist in the SIP signaling path
   between the originating UAC and final terminating UAS, which go
   beyond the definition of a Proxy, performing functions not defined in
   standards-track RFCs.  The only term for such devices provided in
   [RFC3261] is for a Back-to-Back User Agent (B2BUA), which is defined
   as the logical concatenation of a User Agent Server (UAS) and User
   Agent Client (UAC).

   There are numerous types of SIP Back-to-Back User Agents (B2BUAs),
   performing different roles in different ways.  For Example IP-PBXs,
   SBCs and Application Servers.  This document identifies several
   common B2BUA roles, in order to provide taxonomy other documents can
   use and reference.
