VoIP, along with text-based systems such as instant messaging, is likely to gradually replace the circuit-switched telephone system. VoIP offers the promise of global and low-cost communications. However, these attributes also make VoIP a promising target purveyors of unsolicited bulk communications. Unsolicited phone calls, sometimes referred to as "spit" (Spam over Internet Telephony) can be even more annoying and disruptive than email spam. For example, such phone calls may arrive in the middle of the night or may disrupt a business meeting. Such calls may be used for advertising or for soliciting private information by social engineering, extending the threat of phishing into a new realm.The social meaning of trust, reputation, and nuisance are quite different for interactive voice communication compared to e-mails.This proposal describes a comprehensive call admission control framework for accepting, rejecting or forwarding incoming calls to a voice mail system. We will be formalizing notions of trust and reputation for voice communications. One such mechanism is the notion of trust paths that reflect previous communication relationships between users and domains. We plan to devise methods for integrating several social-technical methods for minimizing false rejections.The methods will be tested in a VoIP security testbed being developed by four universities (UNT, Columbia, Purdue and UC Davis). Results will be fed back into on-going standardization activities in the IETF and elsewhere.

VoIP以及基于文本的系统（例如即时消息传递）可能会逐渐替换电路开关的电话系统。 VoIP提供了全球和低成本通信的希望。 但是，这些属性也使VoIP成为未经请求的批量通信的有希望的目标供应商。 与电子邮件垃圾邮件相比，未经请求的电话，有时被称为“ Spit”（互联网电话垃圾邮件）可能更令人讨厌和破坏。 例如，此类电话可能会在深夜到达，或者可能会破坏商务会议。 这种呼叫可用于广告或通过社会工程来征求私人信息，将网络钓鱼的威胁扩展到新的现实中。与电子邮件相比，交互式语音交流的信任，声誉和滋扰的社会含义大不相同。本提案描述了一个全面的呼叫招生控制框架，拒绝或转发了语音邮件系统的拒绝或转发呼叫。 我们将正式化语音通信的信任和声誉的概念。 一种这样的机制是信任路径的概念，反映了用户和域之间以前的通信关系。 我们计划设计用于整合几种社会技术方法，以最大程度地减少错误拒绝的方法。该方法将在由四所大学（UNT，哥伦比亚，普渡大学和UC Davis）开发的VoIP安全测试中进行测试。 结果将被反馈到IETF和其他地方正在进行的标准化活动中。
