Cell phones cannot dial DSN numbers. When dialing a DSN number from a United States installation to another United States installation, it is unnecessary to dial the DSN 312 area code. When dialing a DSN number to/from overseas locations, the DSN area code must be included. The operator can be reached at commercial (719) 567-1110.
