Abstract:
1. A method for remote loopback testing across two or more networks with dissimilar transport technologies, wherein control of gateways at the edge of a first network is based upon a Media Gateway Control Protocol/Network-Based Call Signaling (MGCP/NCS) protocol, data is transported on the first network using a first traffic protocol, and data is transported on the second network using a second traffic protocol, and wherein an interface gateway provides an interface between the first network and the second network, the method comprising: receiving, at the interface gateway, a series of digits from a test probe on the first network, the digits comprising an address and a tag, the address identifying a remote endpoint on the second network, and the tag corresponding to a loopback mode; forwarding the digits from the interface gateway to a call agent on the second network, the call agent operable to map the address to the remote endpoint and to map the tag to the loopback mode, the call agent directing the remote endpoint to establish a connection in the loopback mode; receiving, at the interface gateway, a message from the call agent indicating that the remote endpoint is configured in the loopback mode; disabling synchronized source (SSRC) collision detection and echo cancellation on the interface gateway; sending, from the interface gateway to the test probe on the first network, a notification that a connection has been established with the remote endpoint; receiving, at the interface gateway, test data in the first traffic protocol from the test probe; converting the test data to the second traffic protocol at the interface gateway; sending the test data in the second traffic protocol to the remote endpoint; and receiving the test data, at the interface gateway, after being looped back from the remote endpoint.
