Abstract: In one embodiment, a method includes receiving at a protocol translator a first message from a first endpoint to a second endpoint. The first message includes a list of media capabilities of the first endpoint. The method also includes transmitting from the protocol translator a second message to the second endpoint including a media capabilities request header and receiving at the protocol translator a response message from the second endpoint. The response message includes a response header including a list of the media capabilities of the second endpoint.

Abstract: In a particular embodiment, a network device receives, from a first device, a first call request for a second device. The network device may then send the first call request to a redirect server, which can determine where to send the call. The network device receives a response from the redirect server indicating an address to redirect the call request to. The network device then determines a redirect ID for the redirect. The network device sends a message to the first device with the redirect ID where the message indicates that a redirection occurred to the third device. The network device then receives a second call request from the first device that includes the redirect ID. The network device determines if the call was part of a previous redirect. If so, the second call request is sent to the address associated with the redirect ID.

Abstract: Various embodiments provide methods and systems operable to provide access to real time control protocol (RTCP) information for improved media quality control. An example embodiment includes a message processor to receive a message, the message including information indicative of an RTP port identifier, and to add to the received message information indicative of an auxiliary RTCP port identifier; and a message communication component to communicate the information indicative of an auxiliary RTCP port identifier to a node.

Abstract translation: 在特定实施例中，网络设备从第一设备接收第二设备的第一呼叫请求。 然后，网络设备可以将第一呼叫请求发送到重定向服务器，该重定向服务器可以确定在哪里发送呼叫。 网络设备从重定向服务器接收指示将呼叫请求重定向到的地址的响应。 然后，网络设备确定重定向的重定向ID。 网络设备向具有重定向ID的第一设备发送消息，消息指示向第三设备发生重定向。 然后，网络设备从包含重定向ID的第一设备接收第二呼叫请求。 网络设备确定呼叫是否是先前重定向的一部分。 如果是，则将第二呼叫请求发送到与重定向ID相关联的地址。
