Can anyone confirm if there is a limit of 250 prefixes/exchanges in Windows XP Area Code Rules? (CONTROL PANEL, PHONE AND MODEM OPTIONS, DIALING RULES)
I've added a location, then manually added 250 different prefixes/exchanges in the list. The list allows you to enter as many as you want, but once you click OK and go back, it only lists the first 250 of them.
I believe this is a bug in Windows XP but I cannot find any confirmation from Microsoft regarding this.
Some area codes have over 300 different exchanges/prefixes, so this is a problem.
