Abstract: A communication system, method, and components are described. Specifically, a communication system having the ability to carry a transitive context and communicate the transitive context to new participant user agents for continuity through all related call dialogs is disclosed. The transitive context communication is possible through the use of a newly created SIP dialog using a REFER message and/or an INVITE message for all call flows and topology change operations.

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.

Abstract: To deal with ANAT/IP version incompatibility, a communication endpoint registers with a communication system using a SIP REGISTER message. For example, the communication endpoint registers when it boots up. The SIP REGISTER message indicates that the communication endpoint: does not support the Alternative Network Address Type (ANAT) protocol or is one of IPV4 intolerant or IPV6 intolerant. When a SIP INVITE message is received with a Session Description Protocol (SDP) offer that comprises the ANAT protocol or an IP address that is opposite of the IP version intolerance of the communication endpoint, a 4XX SIP response message is sent to the sender of the SIP INVITE to indicate the incompatibility. In response, to receiving the 4XX SIP response message, the SIP INVITE is modified to be compatible with the capabilities of the communication endpoint.

Abstract: The concept of a centralized communication log is provided. Anchor points, and specifically Session Initiation Protocol (SIP) anchor points, serve as a media and call control point that is established on a per-user basis which can then be leveraged by a communication log application. Such a communication log application is able to determine accurate and real-time communicant information for a communication session and populate a centralized communication log with the same. Such a communication log is, therefore, accurate with respect to multiple users in a system, highly available, and scaled horizontally.

Abstract translation: 提供集中通信日志的概念。 锚定点，特别是会话发起协议（SIP）锚点，用作基于每个用户建立的媒体和呼叫控制点，然后可以由通信日志应用来利用。 这样的通信日志应用程序能够确定用于通信会话的准确和实时的通信者信息，并且填充具有该通信日志的集中通信日志。 因此，这样的通信日志对于系统中的多个用户是准确的，高度可用的并且水平地缩放。

Abstract: Systems and methods are described for selecting applications for incorporation into an application sequence. The selected applications provide one or more features to a communication session and the order of applications selected for the application sequence depends, at least in part, on one or more dynamic parameters. The consideration of dynamic parameters for application sequencing provides a more flexible alternative to traditional application sequencing based on static parameters, like user identities.

Abstract translation: 描述了用于选择并入到应用程序序列中的应用的系统和方法。 所选择的应用向通信会话提供一个或多个特征，并且为应用序列选择的应用顺序至少部分取决于一个或多个动态参数。 用于应用程序排序的动态参数的考虑为基于静态参数（如用户身份）的传统应用程序排序提供了更为灵活的替代方案。

Abstract: System and method to perform a directive by a first SIP User Agent (UA) engaged in a peer-to-peer communication session with a second SIP User Agent (UA), the method including: arming the first SIP User Agent (UA) to define the directive; setting a trigger condition in the first SIP User Agent (UA) to perform the directive if the trigger condition becomes true; monitoring, by use of a processor within the first SIP User Agent (UA), for the trigger condition in the communication session; and if the trigger condition becomes true, performing by use of a processor the directive without usage of a back-to-back user agent.

Abstract: An initial request is received to establish a communication session. The initial request contains a communication address of a first communication device. A communication server detects that the communication session cannot be established across a primary network. In response, the initial request is repurposed by changing the first communication address to a second communication address. The changed request is sent to a communication system, which adds a field to the changed request that indicates that the changed request is to be sent via a secondary network. The changed request is sent with the field to the communication server. The changed request with the second communication address is sent to a gateway to establish the communication session across a secondary network. A portion of the communication session is established using the second communication address. The first communication address is sent in the portion of the communication session using Dual-Tone-Multi-Frequency (DTMF).

Abstract translation: 接收初始请求以建立通信会话。 初始请求包含第一通信设备的通信地址。 通信服务器检测到无法通过主网络建立通信会话。 作为响应，通过将第一通信地址改变为第二通信地址来重新初始化请求。 改变的请求被发送到通信系统，该通信系统向改变的请求添加一个字段，指示改变的请求将通过辅助网络发送。 更改的请求将与该字段一起发送到通信服务器。 具有第二通信地址的改变的请求被发送到网关以建立跨越次级网络的通信会话。 使用第二通信地址建立通信会话的一部分。 第一通信地址在通信会话的部分使用双音多频（DTMF）发送。

Abstract: An initial SIP message is sent to establish a first SIP communication session from a first SIP device. The initial SIP message is sent via a first of a plurality of session managers to a second SIP device. After receiving the initial SIP message at the second SIP device and before ending the first SIP communication session, either the first or second SIP device sends a second SIP message. The second SIP message is sent to the first of the plurality of session managers. Either the first or second SIP devices detects that a response SIP message to the sent second SIP message was not received within a defined time period. In response to detecting that the SIP response message was not received within the defined time period, either the first or second SIP device resends the second SIP message to a second one of the plurality of session managers.

Abstract translation: 发送初始SIP消息以从第一SIP设备建立第一SIP通信会话。 初始SIP消息经由多个会话管理器中的第一个发送到第二SIP设备。 在第二SIP设备接收到初始SIP消息并且在结束第一SIP通信会话之前，第一或第二SIP设备发送第二SIP消息。 第二SIP消息被发送到多个会话管理器中的第一个。 第一或第二SIP设备检测到在定义的时间段内没有接收到发送的第二SIP消息的响应SIP消息。 响应于检测到在所定义的时间段内没有接收到SIP响应消息，第一或第二SIP设备将第二SIP消息重新发送到多个会话管理器中的第二SIP消息。
