Example for IP Group Keep-Alive

This example uses a Message Condition rule based on IP Group connectivity status (param.ipg.<Name>.is-alive) to determine the destination of the call. The device routes the calls between IP Groups "ITSP" and "MainServer". "MainServer" is always accessible to the device, but it in turn routes calls to the "Cloud" IP Group, which may not always be accessible(for whatever reason). If "Cloud" is inaccessible (offline), the device routes the call to an alternative server ("AltServer").
