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: Disclosed are a method, apparatus and system for interworking between H.320 or H.324 and SIP. The method comprises receiving a SIP message indicative of capabilities supported by a first endpoint device and deferring responding to the SIP message. The method further comprises receiving from a second endpoint device an H.320 or H.324 message indicative of the capabilities supported by the second endpoint device in response thereto responding to the SIP message thereby to establish a media communication channel between the first and second endpoint devices based on their respective capabilities.

Abstract translation: 公开了用于在H.320或H.324与SIP之间进行互通的方法，装置和系统。 所述方法包括接收指示由第一端点设备支持的能力并推迟响应于所述SIP消息的SIP消息。 该方法还包括从第二端点设备接收指示第二端点设备支持的能力响应于该SIP消息的H.320或H.324消息，由此建立第一和第二端点之间的媒体通信信道 设备基于各自的功能。

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。
