To call a DSN (Defense Switched Network) phone from a cell phone, you need to use a specific dialing format. Typically, you'll dial a DSN prefix followed by the DSN number, often including an area code or country code. If calling from outside a military base, you may also need to use an international access code. It's important to check with your military communication guidelines for the correct dialing procedure.
To dial to the United States from an overseas military DSN (Defense Switched Network), you typically start by dialing the DSN access code (usually "DSN" or a specific prefix) followed by the area code and the local number.

The Defense Switched Network (DSN) is the internal telephone network for the United States military. A DSN number has the same structure and appearance as a regular U.S. phone number; for example, the DSN operator can be reached on DSN 312-560-1110. However, the area codes and prefixes do not correspond to numbers on the public telephone network, although the last four digits are often the same. You can only dial a DSN number from a telephone at a U.S. Department of Defense facility, including military bases and other facilities, or certain other U.S. government facilities. The commercial (PSTN) number for the DSN operator is +1 719 567 1110. DSN area code 312 covers the entire Continental United States, including regular area code 336 in North Carolina. However, the DISA DSN directory does not include any DSN numbers with public phone numbers in area code 336, and there is no DSN area code 336.
