Abstract: The subject disclosure describes solutions for graphically displaying hierarchical relationships between a network underlay and a network overlay. In some aspects, a method of the technology includes steps for aggregating associations between each of a plurality of physical network devices and one or more virtual network entities, displaying two or more pivot options that graphically represent the physical network devices and/or the virtual network entities, and receiving a pivot selection indicating at least one physical network device or virtual network entity for which hierarchy information is requested by a user. In some aspects, the method can further include steps for graphically displaying one or more layers of a network hierarchy based on the pivot selection. Systems and machine-readable media are also provided.

Abstract: 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.

Abstract: In one embodiment, interworking procedures between H.323 and SIP ensure that in-band tones and announcements, along with local and remote ringback, are properly played or generated.

Abstract: An apparatus and method for negotiating media capabilities is described. The method may comprise receiving an invite to establish a connection between a caller endpoint device and one of a plurality of callee endpoint devices of a shared line and identifying an initial common media capability between the caller endpoint device and the plurality of endpoint devices. Thereafter, the method may comprise negotiating a connection between the caller endpoint device and the callee endpoint device using the common media capability and determining if the caller endpoint device and the callee endpoint device have a common enhanced media capabilities. The connection may be re-negotiated using the enhanced media capability.

Abstract: Various embodiments provide a method and apparatus for providing secure blast calls. An example embodiment includes a secure blast call apparatus including a blast component to determine if a secure or a non-secure call connection is needed and to blast a call connection invite to a plurality of destination endpoints; and a connection component to determine if a responding destination endpoint is a secure or a non-secure destination endpoint, to establish a connection with a secure destination endpoint if a secure call connection is needed, and to establish a connection with a non-secure destination endpoint if a non-secure call connection is needed.
