Edit Phone Number

When you specify phone numbers, use the International Number Format. Enter the country/region code, followed by the local number. Phone numbers should contain only the digits 0123456789. Microsoft Lync 2010 Attendant strips parentheses and additional characters entered. Do not include the international dialing prefix, for example 011 (in the United States) and 00 (European Union, Latin America).
