SIP Back-to-Back User Agents (B2BUAs) can cause unending SIP request
routing loops because, as User Agent Clients, they can generate SIP
requests with new Max-Forwards values.  This document discusses the
difficulties associated with loop detection for B2BUAs and the
requirements for them to prevent infinite loops.

This document is a product of the Sip Traversal Required for Applications to Work Working Group of the IETF.

This is now a Proposed Standard.
