Abstract: In one embodiment, a first end device associated with a first user and a second end device associated with a second user may be participating in a call. During the call, the second user may wish to transfer the call to a third user. The second user has the choice of using a blind transfer or a consult transfer. In one embodiment, a gateway determines interworking information that is needed to interwork an H.450.2 message for the H.323 protocol to a SIP REFER message, and vice versa, to allow the call transfer.

Abstract: Embodiments of the present invention provide techniques for refreshing a session. A session is refreshed using a refresh message that is enhanced for a refresh. For example, the refresh message does not include an SDP or any other message body. The message includes only a reduced header. This reduces time spent building and parsing the refresh message. Also, less bandwidth is used in sending the refresh messages.

Abstract translation: 本发明的实施例提供了刷新会话的技术。 使用增强的刷新消息刷新会话。 例如，刷新消息不包括SDP或任何其他消息正文。 该消息仅包括缩减的报头。 这减少了构建和解析刷新消息的时间。 此外，在发送刷新消息时使用较少的带宽。

Abstract: Systems and techniques to determine that a VoIP call is an inactive media call. One or more counters may be used to determine information indicative of an elapsed time since the last valid media packet sent/received. When the elapsed time exceeds a threshold time, the call is determined to be an inactive media call. The call may be designated as inactive, may be terminated, or other action may be taken based on the determination that the call is an inactive media call.

Abstract translation: 确定VoIP呼叫是非活动媒体呼叫的系统和技术。 可以使用一个或多个计数器来确定指示自发送/接收的最后一个有效媒体分组以来经过的时间的信息。 当经过时间超过阈值时间时，呼叫被确定为不活动的媒体呼叫。 可以将呼叫指定为不活动，可以被终止，或者可以基于呼叫是非活动媒体呼叫的确定来采取其他动作。

Abstract: A system and method for consolidating media signaling to facilitate IP telephony includes receiving a first message exchange in a first protocol from a first endpoint to negotiate a media path with a second endpoint. It is determined to consolidate the first message exchange with additional message exchanges received from the first endpoint in the first protocol. A second message exchange is received in the first protocol from the first endpoint, and information derived from the first message exchange and the second message exchange is consolidated. A first message exchange in a second protocol is initiated to the second endpoint according to the information consolidated from the first and second message exchanges in the first protocol. One or more media flows is facilitated over the media path between the first and second endpoints according to the first and second message exchanges in the first protocol and the first message exchange in the second protocol.

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: In a particular embodiment, interworking between an H.323 protocol and SIP protocol for a call forward/redirection is provided. A first user may call a second user. The second user may have set preferences that cause a call redirection/forward to another end device. The end device may be associated with the second user or another user. Different preferences for the call forward/redirection may be provided. For example, a call may be forwarded all the time, when the second end device is busy, when there is no answer, etc. The redirection may then be performed using a gateway. When end devices communicate using SIP and H.323, the gateway provides interworking to provide the call forward/redirection. For example, the gateway maps a 3xx message in SIP to an H.450.3 message in the H.323 protocol, and vice versa, to provide the call forward/redirection.

Abstract translation: 在特定实施例中，提供用于呼叫转移/重定向的H.323协议和SIP协议之间的互通。 第一用户可以呼叫第二用户。 第二用户可能设置了使呼叫重定向/转发到另一个终端设备的首选项。 终端设备可以与第二用户或其他用户相关联。 可以提供用于呼叫转移/重定向的不同偏好。 例如，当第二终端设备忙时，当没有应答等时，呼叫可以一直转发。然后可以使用网关来执行重定向。 当终端设备使用SIP和H.323进行通信时，网关提供互通以提供呼叫转移/重定向。 例如，网关将SIP中的3xx消息映射到H.323协议中的H.450.3消息，反之亦然，以提供呼叫转移/重定向。

Abstract: In one embodiment, a first message for a video call is received from a first end point. The first end point may be communicating using a first protocol, such as H.323. The first message is for a second end point that communicates using a second protocol, such as SIP. The first message may be an early offer in SIP to start a video call. The first message includes media information that is needed to initiate the video call. The media information is stored and may be later used to initiate the video call with the second end point. The stored media information is mapped to one or more messages that are sent to the second end point to initiate the video call using a slow start initiation procedure in H.323.

Abstract translation: 在一个实施例中，从第一端点接收用于视频呼叫的第一消息。 第一个终点可以是使用诸如H.323之类的第一协议进行通信。 第一个消息是用于使用诸如SIP之类的第二协议进行通信的第二终点。 第一个消息可能是SIP中的早期提供，以启动视频呼叫。 第一个消息包括启动视频通话所需的媒体信息。 媒体信息被存储并且可以稍后用于发起具有第二终点的视频呼叫。 所存储的媒体信息被映射到发送到第二个终端的一个或多个消息，以在H.323中使用缓慢的起始启动过程来发起视频呼叫。
