Using the Telephones on Mount Hamilton
Most of the mountain phones are UCSC campus extensions. To call any campus numbers (459 prefix)--on the mountain or in Santa Cruz--dial 9 followed by the four-digit extension. To get an outside line, dial 6 (you will hear no dial tone following the 6).

Campus extensions on the mounatin are technically within the Santa Cruz area code (831), however, from them one can call many prefixes within the San Jose area (408) toll-free. Nevertheless, when making calls to either of these area codes, one must dial dial 1-831 or 1-408 first. Clipboards are kept near each mountain phone, and include a list of the toll-free prefixes in the 831 and 408 area codes.

Long distance calls should be charged to your credit card. Dial 6 followed by the usual sequence of digits you'd use for making a credit card call. If you make a long distance or toll call and cannot charge it, be sure to record it one of the phonelogs attached to the clipboards kept near all mountain phones. Local and other toll-free calls need not be recorded.
