Abstract
Methods, systems, and computer readable media for verifying the availability of an IP media router during a call setup are described. In one embodiment, the method comprises receiving, from a first endpoint device, a call setup signaling message requesting to establish a call session with a second endpoint device. The method also includes selecting a first media router to establish a first call leg of the call session, performing a route query and MAC address resolution to determine if the first media router is available, and if the first media router is determined to be available, creating a first redirect stream to communicate media packets received from the second endpoint device to the first endpoint device via the first call leg.
