  v: Example 1: A Work fax number ^WPN^FX^^^734^6777777 Example 2: Telephone number with extension ^WPN^PH^^^734^6777777^1 Example 2: Telephone number with internal code. In this example, assume that a corporation's telephone system supports a full external telephone number (area code and telephone number). It also supports internal dialing standards that assign a code to each facility and an extension to each telephone (which happens to be the last 4 digits of the external telephone number, by convention). So, if the Los Angeles facility were assigned code 333, and if the "outside" telephone number at the LA office is (626) 555-1234, the components would be: Component Value area/city code 626 phone number 555-1234 extension 1234 extension prefix 333 The field would be transmitted as follows: ^WPN^PH^^^626^5551234^1234^333 Example 3: speed dial. In this example, assume that a corporation's telephone system supports speed dialing numbers. For example, suppose that a corporation has a contract with a travel agency, whose external number is 1-610-555-1234. Since it is so frequently dialed, the company assigns a speed code: #6098. The components would be: Component Value Area/city code 610 Phone number 555-1234 Speed Dial #6098 The field would be transmitted as follows: ^WPN^PH^^^610^5551234^^^#6098 Example 4: home e-mail address. In this example, assume that a person has a primary home e-mail address such as someone@somewhere.com. The components would be: Component Value Telecommunication Use Code PRN Telecommunication Equipment Type Internet Communication Address someone@somewhere.com The field would be transmitted as follows: ^PRN^Internet^someone@somewhere.com Example 5: work e-mail address. In this example, assume that a person has a work e-mail address such as someone@somewhere.com. The components would be: Component Value Telecommunication Use Code WPN Telecommunication Equipment Type Internet Communication Address someone@somewhere.com The field would be transmitted …
