Can I Call Traditional Phone Numbers Using the Twilio Voice JavaScript and Mobile SDKs?

Yes you can. Apps created using the Twilio Voice SDKs for JavaScript, Android, and iOS act like any other phone that works with Twilio. Users can connect with these apps to existing phones or other devices using the same simple TwiML commands you're already familiar with.

For full details, see Twilio Voice SDKs.
