Abstract: Techniques are provided for sending from a client in a network device a request message configured to request configuration parameters to allow the network device to operate as a source or destination node for packet switched network telephony activity. In response to receiving the request message, sending the configuration parameters from a server configured to retrieve the configuration parameters from a call provisioning server. The configuration parameters are received at the client and passed to a call agent in the network device in order to configure the network device to operate as a source or destination node for packet switched network telephony activity.

Abstract: 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.

Abstract: 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.

Abstract: In one particular embodiment, the secure media includes information sent using secure real-time transfer protocol (sRTP). Supplementary services may include call transfers, forwards/redirects, call hold with music on hold (MOH), call hold with no MoH, call resume, call park, call pickup, call blast etc. In a call flow, a call request may be received from a first device for a second device. The call request may include at least one set of keys and be ready for establishment of an sRTP call. It is then determined that a supplementary service is needed for the call request. For example, a supplementary service may indicate that a call redirect to a third device is required. The gateway then facilitates a supplementary service call with the third device. This is facilitated without contacting the first device to generate a second key after receiving the initial call request.

Abstract: 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.

Abstract: In one embodiment, a session is refreshed using a message that is simplified for refresh purposes. The refresh message that is used is a message used for another purpose in a protocol (e.g., SIP). For example, a reINVITE message may be used as a refresh message. If the reINVITE message is used for its intended purpose, the reINVITE message may be used to change the characteristics of a session. This reINVITE message includes an SDP and full header such that the parameters can be properly changed. However, the reINVITE message may be used to refresh a session. This may be referred to as a simple refresh message. But, the simple refresh message does not include an SDP or any other message body. The simple refresh message includes only a reduced header. This reduces time spent building and parsing the simple refresh message.

Abstract translation: 在一个实施例中，使用简化为刷新目的的消息来刷新会话。 所使用的刷新消息是用于协议（例如SIP）中的另一目的的消息。 例如，reINVITE消息可以用作刷新消息。 如果reINVITE消息用于其预期目的，则reINVITE消息可用于改变会话的特性。 该reINVITE消息包括SDP和完整报头，使得可以适当地改变参数。 但是，reINVITE消息可用于刷新会话。 这可以被称为简单刷新消息。 但是，简单刷新消息不包括SDP或任何其他消息体。 简单刷新消息仅包括缩减的报头。 这减少了构建和解析简单刷新消息的时间。
