Abstract: A Session Initiation Protocol (SIP) session dialog is established between a first user agent and a second user agent. The SIP server receives an in-dialog message for the SIP session dialog. At this point, the SIP server is no longer aware of the SIP session dialog, for example, because the SIP server was rebooted. In response to receiving the in-dialog message, the SIP server sends a request not found message to the first user agent that comprises a server accessible value. The SIP server receives an out-of-dialog SIP REFER message. The out-of-dialog SIP REFER message comprises call state information for the SIP session dialog and is sent based on the server accessible value. The SIP server sends the out-of-dialog SIP REFER message to the second user agent. The SIP session dialog is reestablished. The SIP server can be a SIP proxy server or a Back-to-Back User Agent.
Abstract translation: 在第一用户代理和第二用户代理之间建立会话发起协议（SIP）会话对话。 SIP服务器接收SIP会话对话的对话消息。 此时，SIP服务器不再意识到SIP会话对话，例如，因为SIP服务器已重启。 响应于接收到对话内消息，SIP服务器向包括服务器可访问值的第一用户代理发送请求未找到的消息。 SIP服务器收到对话SIP REFER消息。 不对话SIP REFER消息包括用于SIP会话对话的呼叫状态信息，并且基于服务器可访问值发送。 SIP服务器向对方的SIP REFER消息发送第二个用户代理。 SIP会话对话框重新建立。 SIP服务器可以是SIP代理服务器或背靠背用户代理。

Abstract: During a Session Initiation Protocol dialog setup, the user agent sends an INVITE message with an SDP offer to the conference controller, and the conference controller provides to a media gateway a unique session identifier, a unique conference identifier, and optionally at least one of feature information and/or policy information. If the conference controller restarts, the media gateway may provide the conference controller the unique session identifier, the unique conference identifier, and the optional feature and/or policy information. The conference controller may then generate an out-of-dialog SIP REFER message that includes the unique session identifier and the unique conference identifier and provide the message to the user agent. The user agent, upon receiving the REFER message, may identify a dialog needing replacing, and may provide the conference controller a new INVITE message that allows the conference controller to reconstruct the SIP dialog and optional feature and/or policy information if needed.
Abstract translation: 在会话发起协议对话设置期间，用户代理向会议控制器发送具有SDP提议的INVITE消息，并且会议控制器向媒体网关提供唯一的会话标识符，唯一的会议标识符以及可选地至少一个特征 信息和/或策略信息。 如果会议控制器重新启动，则媒体网关可以向会议控制器提供唯一的会话标识符，唯一会议标识符以及可选特征和/或策略信息。 然后，会议控制器可以生成包括唯一会话标识符和唯一会议标识符的对外SIP REFER消息，并向用户代理提供消息。 用户代理在接收到REFER消息时可以识别需要替换的对话，并且可以向会议控制器提供新的INVITE消息，其允许会议控制器在需要时重构SIP对话和可选的特征和/或策略信息。

Abstract: Embodiments of the disclosure are directed to a call reconstruction server. This server can act as a signaling anchor for various SIP UAs involved in the session and can be included in the signaling path between UAs. More specifically, the reconstruction server can insert an identifier such as a Uniform Resource Identifier (URI) into the headers of SIP signaling messages exchanged between UAs during initiation of a session such as a call or conference. These identifiers can be used to insert the reconstruction servers into the path of the session in a way that “bookends” the other servers and/or processes in the session between the UAs. When one of these servers and/or processes restarts, the reconstruction servers can initiate a reconstruction process that rebuilds the session without relying on specially adapted UAs.

Abstract: A communication session is established between a first communication device and a second communication device. The communication session comprises a first dialog between an application server and the first communication device. The first communication device uses a first network address in the first dialog. In response to an event, such as a first network interface failing, a SIP INVITE with replaces header message is received by the application server with a second address of the first communication device. In response to receiving the SIP INVITE with replaces header message from the first communication device with a second address of the first communication device, the first dialog between the application server and the first device is reestablished using the second network address.
