I have a situation where local calling is available across more than one area code. Only some exchanges in the neighboring area code are local while others are not. I know how to create a route patterns for each individual exchange but I would like to create a pattern that would match a set of exchanges if possible. The problem is the exchanges are not sequential and do not follow a pattern that lends itself easily to wild cards. Is it possible to create set to compare against..eg [303,567,498,613] ?
