Hey Steven, When making an outbound call with Vapi, make sure the phone number is in E.164 format, which means including the **country code and a + s**ign at the beginning. For example, if you're calling a U.S. number, it should look like this:

+19201231234

Also, if you're passing the number in code, make sure it's wrapped in quotes so it's treated as a proper string: '+19201231234' Let me know if that helps!
