The Session Initiation Protocol and Spam
RFC 5039, “The Session Initiation Protocol and Spam”, is an Informational document published in January 2008 by J. Rosenberg, C. Jennings. The canonical text is published by the RFC Editor.
Abstract
Spam, defined as the transmission of bulk unsolicited messages, has plagued Internet email. Unfortunately, spam is not limited to email. It can affect any system that enables user-to-user communications. The Session Initiation Protocol (SIP) defines a system for user-to- user multimedia communications. Therefore, it is susceptible to spam, just as email is. In this document, we analyze the problem of spam in SIP. We first identify the ways in which the problem is the same and the ways in which it is different from email. We then examine the various possible solutions that have been discussed for email and consider their applicability to SIP. This memo provides information for the Internet community.
