Abstract:
1. A method comprising: receiving, with a first network device from a second network device, a signaling message to open a pinhole that, when open, allows a media flow originating from a source endpoint to pass through the first network device toward a destination endpoint, the signaling message comprising: a data field that identifies a source transport address of the source endpoint; a first indicator; and a second indicator; determining, with the first network device, that when the pinhole is open, to allow the media flow originating from the source endpoint to pass through toward the destination endpoint when the media flow identifies the source transport address of the source endpoint instead of a source transport address of the second network device that sent the signaling message in response to the first indicator indicating that the data field represents the source transport address of the source endpoint and the second indicator indicating that the first network device should determine a media flow source transport address for the media flow from the data field; receiving, with the first network device, the media flow identifying the source transport address of the source endpoint instead of the source transport address of the second network device; and when the pinhole is open, sending, with the first network device, the media flow identifying the source transport address of the source endpoint toward the destination endpoint.
