Enhancing anonymity in the Session Initiation Protocol (SIP) is much more than sealing participants' identities. It requires methods to unlink the communication parties and relax their proximity identification. These requirements should be fulfilled under several prerequisites, such as time limitation for session establishment, involvement of several functional entities for session management, inter-domain communications and support of streaming services when the session is established. In this paper we propose the usage of a privacy enhancement framework, called Mist, as a solution to the anonymity issue in SIP. For achieving anonymity, the original Mist architecture was modified to be adapted in the SIP framework. We evaluate the adapted Mist framework to SIP and measure how efficiently it supports anonymity features.
