“…This kind of voice-based Turing test can be used by using the SIP application interaction framework (Rosenberg, 2009). This framework provides information about the capabilities of the devices involved in the call so that an appropriate challenge can be given.…”

Voice over IP telephony reduces communications costs, but it is also subject to spam, i.e. unwanted, unsolicited calls. This paper discusses the problem of spam over IP telephony and reviews published techniques to reject likely nuisance callers. The techniques investigated include content filtering, black lists, white lists, gray lists, call rate monitoring, IP/domain correlation, reputation systems, consent-based communications, address obfuscation, limited-use addresses, computational puzzles, Turing tests, payments at risk, legislation, centralized SIP providers, circles of trust and authenticated identity. The advantages and disadvantages of each are analyzed. It is concluded that no single technique is sufficient and that a framework of multiple techniques is required. One proposed framework is analyzed and it is found that it has limited support for voicemail spam and contact request spam.

“…HTTP is the protocol for web service, and it has no special mechanism for application interaction between the UI client and the UI server. Ref [5] defines a stimulus framework for application interaction in SIP [8]. The framework provides a model for how users interact with applications through user interfaces, and how user interfaces and applications can be distributed throughout a network.…”

“…The framework provides a model for how users interact with applications through user interfaces, and how user interfaces and applications can be distributed throughout a network. For the traditional dual tone multi frequency (DTMF) signals, ref [6] has specified a SIP Event Notification Package for the application interaction, and the event package is consistent with the principles defined in [5]. Except DTMF, a UE with the presentation capable UI [5] have more powerful capabilities, such PC, PDA, so the client-local User interface may be used instead of the client remote UI.…”

The user interaction (UI) function is enhanced to the IMS service architecture by defining the data model between the UI client and the UI server, introducing the user behavior trace function (UBTF), enhancing the interface between a CSCF and a PDFE. Unlike traditional services such as Call Forwarding, Ring Back Tone, etc., which are based on an end user status and/or a pre-provisioned user profile, the services built on this extended architecture enables end users to actively and instantly intervene in session control. The user preferences will be statistically collected into the network by the UBTF based on historical user behavior, and used for future sessions. And the UBTF can also improve the user experience by changing the UI function of a service and cut down the network resource usage.
