A Taxonomy of Session Initiation Protocol (SIP) Back-to-Back User Agents

چکیده

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 RFC 3261 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).

Security testing of session initiation protocol implementations

The mechanisms which enable the vast majority of computer attacks are based on design and programming errors in networked applications. The growing use of voice over IP (VOIP) phone technology makes these phone applications potential targets. We present a tool to perform security testing of VOIP applications to identify security vulnerabilities which can be exploited by an attacker. Session Ini...

RFC 7879 DTLS - SRTP Handling in SIP B 2 BUA

Session Initiation Protocol (SIP) Back-to-Back User Agents (B2BUAs) exist on the signaling and media paths between the endpoints. This document describes the behavior of B2BUAs when Secure Real-time Transport (SRTP) security context is set up with the Datagram Transport Layer Security (DTLS) protocol.

SIP CLF: A Common Log Format (CLF) for the Session Initiation Protocol (SIP)

Web servers such as Apache and web proxies like Squid support event logging using a common log format. The logs produced using these de-facto standard formats are invaluable to system administrators for trouble-shooting a server and tool writers to craft tools that mine the log files and produce reports and trends. The Session Initiation Protocol (SIP) does not have a common log format, and as ...

RFC 7584 STUN Handling in SIP B

Session Initiation Protocol (SIP) Back-to-Back User Agents (B2BUAs) are often designed to be on the media path rather than just intercepting signaling. This means that B2BUAs often act on the media path leading to separate media legs that the B2BUA correlates and bridges together. When acting on the media path, B2BUAs are likely to receive Session Traversal Utilities for NAT (STUN) packets as p...
