"Use a Verified Caller ID for Outbound Calls Using a Verified caller ID allows you to validate a non-Twilio phone number to be used as a caller ID when placing outbound calls from Twilio. This can be a good solution for placing calls that appear to be from a local number, even if we don't offer Twilio numbers locally. To make this work, all you need to do is verify a number that you own. You can then use this verified phone number as the “From” number when you make outbound voice calls from our platform."
