Media gateway device, and media path configuration method

A media path setting method executed by a media gateway device for relaying data on a media path set between terminals of a plurality of communication networks, wherein the media gateway device includes a first interface for connecting to a first network among the plurality of communication networks, a second interface for connecting to a second network among the plurality of communication networks, and a test command issuing unit including one or more processors, the media path setting method comprising

• by the test command issuing unit, establishing, when a mapping between the first interface and the second interface is set by first setting data for associating a media path ID in the first interface with a termination ID in the first interface and second setting data for associating a media path ID in the second interface with a termination ID in the second interface, a test call for a media path passing through the first interface and the second interface based on the mapping and testing, by assigning a resource to the media path that is established, whether data transmission and reception are possible on the media path that is established.

The media path setting method further comprises:

• changing, by the test command issuing unit, when data transmission and reception are unsuccessful on the first media path that is established, the mapping between the first interface and the second interface to another untested combination;
• and
• then, again, establishing, by the test command issuing unit, a test call for a second media path and tests, by assigning a resource to the second media path that is established, whether data transmission and reception are possible on the second media path that is established.
