SIP Security Status Quo and Future Issues
Today, the session initiation protocol (SIP) is the predominant protocol for Voice-over-IP (VoIP) signalling. The intention of this paper is to present an overview of VoIP security issues both current and future – focusing on SIP. We start by presenting some fundamental differences between VoIP and the public switched telephone network (PSTN). We then look at specific problems for SIP signallin...
متن کاملSip Security the Session Inititation Protocol (sip)
Ubiquitous worldwide broadband Internet access as well the coming of age of VoIP technology have made Voice-over-IP an increasingly attractive and useful network application. Currently the “human-readable” Session Initiation Protocol (SIP) which is based on a simple HTTP-like request/response exchange is steadily gaining headway against the considerably more complex ASN.1 encoded H.323 Multimed...

متن کاملUser authentication in SIP
Today Voice over Internet Protocol (VoIP) is used in large scale to deliver voice and multimedia over the packet data networks, such as the Internet. The Session Initiation Protocol (SIP) is widely used as a signalling protocol for VoIP. As SIP is being used more, the security of it is an important issue. In this paper, we concentrate on user authentication in SIP. We examine current solutions ...
متن کاملRFC 7200 SIP Load
This specification defines a load-control event package for the Session Initiation Protocol (SIP). It allows SIP entities to distribute load-filtering policies to other SIP entities in the network. The load-filtering policies contain rules to throttle calls from a specific user or based on their source or destination domain, telephone number prefix. The mechanism helps to prevent signaling over...
