摘要： A system for verifying caller ID information in received VoIP calls. In particular implementations, a method includes receiving a caller identification (ID) identifying a calling party telephone number in a call initiation message transmitted from a VoIP call agent; determining the identity of the VoIP call agent; verifying that a public switched telephone network (PSTN) call to the calling party telephone number would arrive at a VoIP call agent having the determined identity; and applying, responsive to the call initiation message, one or more rules based at least in part on the verifying step.

摘要： A system for verifying VoIP call routing information. In particular implementations, a method includes verifying one or more Voice-over-Internet-Protocol (VoIP) call agents for respective destination telephone numbers based on demonstrated knowledge of previous public switched telephone network (PSTN) calls to the respective destination telephone numbers; receiving a call initiation message identifying a destination telephone number; and conditionally initiating a call over a VoIP network to a target VoIP call agent, or over a circuit switched network, based on whether the target VoIP call agent has been verified for the destination telephone number identified in the call initiation message.
摘要翻译： 一种用于验证VoIP呼叫路由信息的系统。 在特定实施方式中，一种方法包括基于对先前公共交换电话网（PSTN）对各个目的地电话号码的呼叫的证明知识来验证用于各个目的地电话号码的一个或多个因特网协议（VoIP）呼叫代理; 接收标识目的地电话号码的呼叫发起消息; 并且基于目标VoIP呼叫代理是否已经被验证为在呼叫发起消息中标识的目的地电话号码，有条件地通过VoIP网络向目标VoIP呼叫代理或电路交换网络发起呼叫。

摘要： An authentication agent may cryptographically identify a remote endpoint that sent a media initialization message even though intermediate devices may modify certain fields in the message after a signature is inserted. The originating endpoint's agent may create the signature over some fields of the message using an enterprise network's private key. The agent may insert the signature into the message and send the message to a recipient endpoint's authentication agent. The recipient agent may verify the signature, receive a certificate including a second public key, and challenge the identity of the originating endpoint in order to confirm that identity. This challenge may request a confirmation that the originating endpoint knows the private key corresponding to the second public key and may occur while running encrypted media at the endpoints. After the originating endpoint is authenticated, the endpoints may exchange encrypted and/or unencrypted media.
摘要翻译： 认证代理可以密码地标识发送媒体初始化消息的远程端点，即使中间设备可以在签名被插入之后修改消息中的某些字段。 始发端点的代理可以使用企业网络的私钥在消息的某些字段上创建签名。 代理可以将签名插入消息中，并将消息发送到接收方端点的认证代理。 接收方代理可以验证签名，接收包括第二公钥的证书，并且对发起端点的身份进行质询以便确认该身份。 该挑战可以请求确认始发端点知道与第二公钥相对应的私钥，并且可能在端点处运行加密媒体时发生。 在始发端点被认证之后，端点可以交换加密和/或未加密的媒体。

摘要： Techniques are described for the use of a cryptographic token to authorize a firewall to open a pinhole which permits certain network traffic to traverse firewalls. An initiating endpoint requests a token from a call controller, which authorizes a pinhole though the firewall. In response, the call controller may generate a cryptographic authorization token (CAT) sent towards the destination endpoint. The call controller may generate the token based on an authorization ID associated with the call controller, a shared secret known to both the call controller and the firewall, and data specific to the media flow for which authorization is requested.
