    Abstract: In accordance with at least one embodiment of the present invention, a communication apparatus includes a communication unit configured to send and receive messages on a network. Each message has a message header configured to include a plurality of header fields, where the message header includes a suppression header field that indicates a request to suppress at least one header field in at least one subsequently sent or received message. The communication apparatus is configured to establish a suppressed header field message exchange session with a peer on the network so that at least one subsequent message exchanged between the communication apparatus and the peer is free of at least one suppressible header field.

    Abstract translation: 根据本发明的至少一个实施例，通信设备包括被配置为在网络上发送和接收消息的通信单元。 每个消息具有被配置为包括多个报头字段的消息报头，其中消息报头包括指示在至少一个随后发送或接收的消息中抑制至少一个报头字段的请求的抑制报头字段。 通信装置被配置为与网络上的对等体建立抑制的报头字段消息交换会话，使得在通信装置和对等体之间交换的至少一个后续消息没有至少一个可抑制的报头字段。

    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 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。
