Unit – International Dialing

This unit explains how Fastcall (via Twilio) handles calls to phone numbers outside the US and Canada, and how to best record phone numbers.

Fastcall and international numbers

You’ll find it easier to always record phone numbers in Salesforce with the correct international dialing prefix, as this will make the behaviour of all phone applications more predictable.

Fastcall will handle all phone numbers as follows:

  1. If the phone number begins with a ‘+’, it will be dialed as-is; OR
  2. If the phone number does not being with a ‘+’:
    1. If the phone number begins with a ‘0’, the 0 will be stripped; AND
    2. The default country code set in Salesforce for the org or user will be prepended to the phone number

Examples with default country code set to +1

See the training unit on regional settings for information on how to change your org and user default country codes.
