Dialing Tips

  • If you are in an office or building with a main switchboard or PBX, make sure you have a live outside line by dialing '9' or similar
  • Some mobile carriers provide shortcuts for making international calls - generally, by changing if or how an IDD is dialed. E.g., In Canada, t-mobile allows you to dial a '+' instead of an IDD when calling international numbers.
  • Most calling cards do not require an IDD - but generally do require dialing of additional access numbers and identifying codes
  • Most VoIP services do not require an IDD - but VoIP dialing procedures vary widely, so check dialing for your service carefully
  • Make sure you don't have an extra '1' in your number (see step #2)
