Abstract:
A method for providing an alternate signaling connection, comprising the following steps:receiving a first signaling message in a first protocol on a first signaling device on a first network from a second network to create a connection between a first network device on the first network and the second network;converting the first signaling message into a second signaling message in a second protocol on the first signaling device;determining from the first signaling device that a first signaling connection between the first signaling device and the first network has failed;sending the second signaling message from a second network device associated with the first signaling device to a third network device on the second network over a second connection;sending the second signaling message from the third network device on the second network to a fourth network device on the first network over a third connection;sending the second signaling message from the fourth network device to the first network device on the first network over a fourth connection, thereby providing an alternate signaling connection to the first network device on the first network from the first signaling device.
