Abstract: A provisioning client obtains an identifier from a public server and a one-time password from a trusted server. The provisioning client combines the one-time password with the identifier to create an activation code for a client device and presents the activation code to the client device. The activation code enables the client device to download trusted cryptographic information from the trusted server in a communication session that is secured using the one-time password.

Abstract: A trusted server receives a request for an activation code, which includes an identifier associated with the trusted server and a one-time password, for a client device. The trusted server obtains the identifier from a public server, generates the one-time password, and combines the one-time password with the identifier to create the activation code. The trusted server provides the activation code to a provisioning client, which presents the activation code to the client device. The trusted server and client device secure a communication session using the one-time password as a shared secret. The trusted server downloads trusted cryptographic information to the client device over the secure communication session.

Abstract: A client device bootstraps against a trusted server by obtaining an activation code that includes an identifier and a one time password. The client device sends a message to a public server requesting an address of a trusted server associated with the identifier. The client device receives the address of the trusted server from the public server and initiates a communication session with the trusted server at the address provided by the public server. The one time password is used as a shared secret to secure the communication session. The client device downloads cryptographic information from the trusted server.

Abstract: Multicast media notifications are provided when unicast media encoders are unavailable to serve endpoints that send a communication session request to a call control device. When the call control device receives a communication session request from an endpoint, a determination is made as to whether any one of a plurality of unicast media encoders is available for the communication session request. When it is determined that none of the plurality of unicast media encoders is available, the endpoint is connected to a multicast media encoder that presents a multicast media notification to the endpoint. The multicast media encoder generates a video keyframe associated with the multicast media notification, synchronizes the video keyframe to a starting point of audio, and outputs the synchronized video keyframe.

Abstract translation: 当单播媒体编码器不可用于向呼叫控制设备发送通信会话请求的端点时，提供组播媒体通知。 当呼叫控制设备从端点接收通信会话请求时，确定多个单播媒体编码器中的任一个是否可用于通信会话请求。 当确定多个单播媒体编码器中没有一个可用时，该端点连接到向端点呈现组播媒体通知的多播媒体编码器。 多媒体媒体编码器生成与组播媒体通知相关联的视频关键帧，将视频关键帧同步到音频起点，并输出同步的视频关键帧。
