How do you call phone numbers with extensions?
|Knowledge Article Number||000212806|
|Description||If you have the phone field with an extension in it you cannot use the CTI soft phone, Salesforce1, or Salesforce Classic, as it is not a valid phone number.|
|Resolution||To workaround this, you can create a custom number or text field for the phone extension. The only difference is, you would need to manually input the extension number after you make the call.|
