Add forwarding number to the Twilio number programmatically

Question

How to forward the call to an US local Twilio number from any mobile to any US number?

Its seems to me that I will have to use TwiML to achieve that. Moreover, the supporting doc in https://support.twilio.com/hc/en-us/articles/223179908-Setting-up-call-forwarding#devs is not seeming to show the TwiML correctly. And also with that way I will have to use verb.

Can I not directly call from the number pad of my mobile to the Twilio number so that the call can be received from the forwarding number?

Can I not set a forwarding number to the purchased number programmatically?

Answer 1

Twilio evangelist here.

To forward a call made from your mobile device to a Twilio number to another US phone number you can use the <Dial> verb:

<Response>
    <Dial callerId="[your_twilio_phone_number]">[target_phone_number]</Dial>
</Response>

This part of the Voice Quickstart for PHP shows this and might be useful for you:

Hope that helps.

Answer 2

This was what I went with before getting the answer from Twilio support but after the answer from @Devin Rader and from my client.

here is a great tutorial doing call forwarding programmatically, https://www.twilio.com/docs/tutorials/walkthrough/call-tracking/php/laravel. Yes, you can definitely set the TwiML programmatically on the numbers, take a look at the documentation on provisioning phone numbers, https://www.twilio.com/docs/api/rest/incoming-phone-numbers. You can also set the number so that Twilio makes a call to your application and your application delivers TwiML dynamically.
