What is the correct way to dial a phone number from a Cisco phone

Resolution

1. For calls to other VoIP phones:

   1. Dial 9-1-(area code) and the seven-digit phone number
   • Examples
     • Local: 9-1-605-677-1234
     • Long Distance: 9-1-212-222-1234
     • Toll-Free: 9-1-800-444-4444
3. For International Calls
   1. Dial 9-011 and the phone number
   • Example
     • Disneyland Paris: 9-011-33-825-30-05-00
