with disa just make sure that calls allowed are local only and no one will misuse it.. passwords can be shorter that way. stealing ld is not the threat it used to be but it still happens.. 90 percent of toll fraud back in the 80's and 90's was drug deals between here and south america.. they didn't steal toll for the price, they just didn't want 1,000's of calls to be monitored or traced back to them.. now with through away cell phone designed with crooks in mind, they don't worry about cost or law enforcement.
