摘要： Combining signals includes receiving signals from communication devices, where each signal is associated with a content describing the signal. The following is repeated for each signal: the content associated with a signal is examined, whether the signal is a voice signal is determined in accordance with the content, and the signals are sent to a signal combiner in accordance with the determination of whether the signal is a voice signal. The signals are combined at the signal combiner.

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： A system may provide trust relationship information for a telephone number, where the trust relationship information may indicate whether one or more nodes consider a target node as including or as being associated with a VoIP call agent for the telephone number based on demonstrated knowledge of a PSTN call. The system may determine a target trust relationship to the target node based on the trust relationship information, where the target trust relationship indicates a level of trust a validating node has in the target node being associated with or including the VoIP call agent for the telephone number, and where validating node and the one or more nodes may be in different respective administrative domains of a network.

摘要： A method for establishing a communication session between two endpoints that do not both support secure media includes receiving a registration from a first endpoint. The registration indicating the first endpoint supports secure media and non-secure media. The method also includes receiving a registration from a second endpoint. The registration indicating the second endpoint supports non-secure media. The method also includes receiving a request to establish a communication session between the first endpoint and the second endpoint using secure media. The method further includes establishing the communication session between the first endpoint and the second endpoint via the communications platform using non-secure media.

摘要： A system and a method are disclosed for authenticating a subsequent callback from a public safety answering point (PSAP) in response to a user agent's initial emergency call. In one embodiment, the user agent forwards a token to the PSAP during the initial call, and the PSAP returns the token during callback. The PSAP is authenticated when the forwarded and returned tokens match. In another embodiment, the user agent encrypts a token using a Public Key Infrastructure and forwards the encrypted token to the PSAP. The PSAP decrypts the token and, upon callback, includes a signed digital certificate based on the token. The user agent authenticates the PSAP when the decrypted digital certificate matches the originally sent token. In yet another embodiment, the user agent forwards a first token to the PSAP. Upon callback, the user agent forwards a second token to the PSAP. The PSAP performs a function on the pair of received tokens and forward the result to the user agent. The user agent performs the same function on the same tokens to obtain a local result. The user agent authenticates the PSAP when the local and forwarded results match.

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 may generate from a first value, based on rounding information, a first security key that matches a second security key whenever the first value and a second value from which the second security key is generated differ by less than a non-zero predetermined amount. The second security key may be generated from the second value rounded to a multiple of a rounding interval that is nearest to the second value. The rounding information may include a rounding direction indication. The rounding direction indication may indicate the direction in which the second value is rounded to the multiple of the rounding interval nearest to the second value.
