In this entry we will discuss International Calls. Within VoIP.MS we consider "International" calls that ends to numbers outside US48 and Canada.
When you try to reach an International Number, you must follow these instructions:
In your voip.ms account you will be able to choose from 2 different dialing modes (Customer Portal >> Main Menu >> Account Settings >> General.)
- North America (NANPA): You'll need to use the 00 or 011 prefix to call international numbers. - E164 : You dial numbers by using country code first, you don't need to send the 00 or 011 prefix to call international numbers.
- Please be sure International calls are enabled on your account, to enable them ( Go to your Customer Portal >> Main Menu >> Account Settings >> Account Restrictions).
- Please select the option "Yes - International Calls Enabled"
- If you want to place an International Call, make sure that you are properly dialing the number.
* International Call : 00 or 011 + Country Code + Area Code + Number
-011 - US exit code; must be dialed first for all international calls made from the USA or Canada - country code - area code - 2 - 3 digit area codes (if it's required) - phone number - 7 - 8 digits; area code + number total 10 digits
If your International Call does not connect, please trying doing this:
- Verify that you have Allowed the call to this country (Customer Portal >> Main Menu >> Account Settings >> Account Restrictions).
- Try reaching this number with our Value or Premium route ( Customer Portal >> Main Menu >> Account Settings >> Account Routing).

- Make sure you are sending a valid 10 digit CallerID number, for main account: ( Customer Portal >> Main Menu >> Account Settings >> General Tab, CallerID Number) for a sub account: ( Customer Portal >> Sub Accounts >> Manage Sub Accounts >> Edit, CallerID Number)
