Abstract:
In many SIP deployments, SIP entities exist in the SIP signaling path
between the originating and final terminating endpoints, which go
beyond the definition of a SIP 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 SIP User Agent Server
(UAS) and User Agent Client (UAC).
There are numerous types of SIP Back-to-Back User Agents, performing
different roles in different ways. For Example IP-PBXs, Session
Border Controllers (SBC) [RFC5853] and Application Servers (AS).
This document identifies several common Back-to-Back User Agent
roles, in order to provide taxonomy other documents can use and
reference.
