A question was posed about how to set an offnet resource to match more than one regex pattern match in the rules[ ] array. There are 2 methods to achieve this behavior. Both (as far as I know) are acceptable, and vary only in readability. When viewing a carrier document in the offnet database in couch, you'll notice there is an array element for "rules". In the world of regular expressions, capture groups are separated by a pipe "|". So if you're looking for one regular expression to match more than one string, you can use the method listed below. In my example, I want this carrier to match a specific number in Italy, and also any calls to the Netherlands, country code 31. In order to match, the number must be exactly "+390805345208", OR +31 followed by at least 9 digits. "rules": [ "^\\+(390805345208)$|^\\+((31)\\d{9,})$" ] Looking above, this may be hard for some people to read, so it can also be written as 2 individual expressions because the rules element is an array: "rules": [ "^\\+(390805345208)$", "^\\+((31)\\d{9,})$" ]
