摘要： A method for interworking supplementary call services between different VOIP protocols is provided. The method comprises receiving, during a call between a first end device and a second end device, a first message in a first protocol format for the second end device to transfer the call to a third end device; determining interworking information to interwork the first message to a second message in a second protocol format; generating the second message based on the interworking information, such that the second message initiates the call transfer to the third end device.

摘要： A method and apparatus is described to convert DTMF packets at a network node in an IP network. The method may comprise receiving an Internet Protocol (IP) packet at the network node connected via a first IP network link to a first network device, and connected via a second IP network link to a second network device. The method may determine a first DTMF packet format for the first IP network link and a second DTMF packet format for the second IP network link and detect that only one of the first or second DTMF packet formats is in-band voice DTMF. Thereafter, the method may convert the received IP packet from the first DTMF packet format to the second DTMF packet format.

摘要： 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.
摘要翻译：在一个实施例中，与第一用户相关联的第一终端设备和与第二用户相关联的第二终端设备可以参与呼叫。在通话期间，第二用户可能希望将呼叫转移到第三用户。第二个用户可以选择使用盲转或咨询转帐。在一个实施例中，网关确定将H.323协议的H.450.2消息互通到SIP REFER消息所需的互通信息，反之亦然，以允许呼叫转移。

摘要： 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.
摘要翻译：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。

摘要： 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.

摘要： In one implementation, an intermediary receives a message from an endpoint, includes a flow around address and a flow through address to a second network device listed in the first message. The intermediary requests another endpoint to perform a connectivity test to determine the reachability of the originating endpoint. The connectivity test may be performed using methods such as ping, probe, interactive connectivity establishment (ICE), or session traversal utilities for network address translation (STUN). The intermediary may request originating endpoint a similar connectivity check and establish a media stream based on results of the connectivity tests. The media stream may be a voice over internet protocol (VoIP) call.

摘要： We describe a system embodiment comprising generating a Secure Real-Time Transport Protocol (SRTP) encapsulated packet and including a secure media indicator into the SRTP encapsulated packet. The method further comprises inserting the SRTP encapsulated packet into an SRTP voice stream associated with an active call between a source and a destination endpoint and indicating an end-to-end secure call between the source and destination endpoints responsive to the secure media indicator.And we describe a method embodiment comprising transmitting a request message from a source endpoint to a destination endpoint participating in an active call and setting a secure media flag in the request message at each node in a signaling path associated with the active call. The method further comprises returning a response message from the destination endpoint to the source endpoint responsive to the request and indicating an end-to-end secure call between the two endpoints.
