摘要： Techniques for providing a bulk refresh of sessions in a network are provided. A plurality of session identifiers for sessions that were created are determined. These session identifiers may be included in a bulk refresh message. The bulk refresh message is sent to a device configured to determine if sessions associated with the plurality of session identifiers are active or inactive. The device then sends a response to the refresh requestor. The response can be used to determine which sessions are active or inactive. After the determination, actions can be taken in order to clear the hanging session. For example, the session may be torn down or a BYE message may be sent to end the session on a peer device.

摘要： In one embodiment, a signaling message is received from an endpoint. It is determined from the signaling message whether, prior to sending the signaling message, the endpoint performed network address translation on the body of the signaling message. If it is determined from the signaling message that, prior to sending the signaling message, the endpoint did not perform network address translation on the body of the signaling message, application layer gateway functionality is applied to the body of the signaling message such that a modified signaling message is generated.

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： Disclosed are apparatus and methods for managing session data in a session border controller (SBC), where the session data is sent from a first node, such as a first phone, to a second node, such as a registrar or second phone. In one example embodiment, the following operations are performed in a first intermediary node that is configured to provide network address translation (NAT) for both a header and payload of a session packet and has an inside interface coupled with a second intermediary node that is configured to perform NAT for only a header of session packets. It is determined whether an end node is sending session packets that are not used to set up a session and that result in a binding that was formed by the second intermediary node being retained. The binding associates inside and outside addresses of the end node, and an end node is defined as a node that originates a session packet. It is determined whether to inhibit a registration throttling process from being performed by the first intermediary node, that results in the binding being retained, based on whether it is determined that the end node is sending session packets that are not used to set up a session and that result in the binding being retained.

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.
