摘要： 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.

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 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.
