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.
