Important: The order of phone usage records in Voice policies is significant because, when matching users to routes, the server compares phone usage records from top to bottom. If the first phone usage record matches the call route, the server quits looking and routes the call to the corresponding gateway. The remaining phone usages provide backup in the event of route congestion or call failure. To expedite call routing, the order of phone usage records should typically proceed from general to specific.
